In a practical application, the stone production line is mainly composed of feeding equipment, crushing equipment, screening equipment and conveying equipment.  And the general crushing equipment mainly includes primary crushing and secondary crushing crushers.  The customers can choose different modes of crushers according to different requirements of materials and granularity.
Now, let's introduce commonly used crushing equipment to you.  The rock crusher for sale as coarse crushing machine is generally used to crush hard or medium hardness raw materials, which is not suitable for crushing sticky ores.  Chinese cone crusher as medium and fine crushing machine is generally applied to crush hard or medium harness materials.  Impact crusher machine is suitable for coarse, medium and fine crushing, which has big crushing ratio and is suitable for crushing medium or under medium hardness materials.  Impact crushers make material crushing easy and convenient, which belongs to one of the best crushing machines of mineral.
Gyratory crusher is a kind of newly researched crushing machine, which can replace jaw crusher and cone crusher, which has broad market prospect in ore beneficiation industry.  Then, what makes gyratory crusher better than jaw crusher? There are mainly six factors:
1. Fine effect is especially good.
2. Processing capacity is bigger.
3. There is little working vibration.
4. Energy-saving effect is remarkable.
5. It has low costs and easy maintenance.
6. There is smaller steel consumption of lining board.
However, there are also disadvantages of gyratory crushers existing.  It has higher requirements on the wearing parts, which needs to be replaced frequently.
With the continuous development of modern science and technologies, the consumption of mineral resources is growing, so, the requirements on the comprehensive utilization rate of mineral resources are also increasing gradually.  The Environmental protection laws are being perfected gradually, which also promotes the green development of mining machinery industry.

To pay more attention to the energy-saving is not one trivial matter any more, which is tightly related to the development fate of one enterprise, and which can determine one tendency of one field.  The winner of the future market competitors is not only belonging to the large-scale enterprises any more, but belonging to those enterprises owning the leading performance characteristics of their crusher machine and lowering the energy consumption, so that is the reason why all of the enterprises should come up with some ways to quicken the speed of improving the energy-saving technology and to realize the energy-saving production in order to improve the competitive strength in the overall mining market.  At this right minute, there still is one big gap between our national cement industry and that of the overseas on the energy consumption.  The result of one enterprise on energy saving is not only related to the administrative principle, the quality of the staff, but also having the great relationship to the equipment and technological level of this enterprise.
The only way to realize the energy saving production of cement industry is to improve the technological level, and introducing the advanced technology equipment, and crushers are the necessary equipment in the cement production process.  The new type crushers have achieved so much on the energy consumption, which is beneficial to the energy-saving production of one enterprise.

At present, there exists many problems in the working process of high strength powder grinding mill, i. e, grinding speed is slow, raw materials are wasted too much and abrading the machine seriously and so on.  As we all know, grinding speed determines work efficiency of high strength mill , especially for some difficult-broken materials, such as quartz.  How to improve the crushing efficiency of quartz crushing, this article will give you a weapon!To improve work efficiency, firstly we have to see the whole combination of each machine, only if which works perfectly, efficiency certainly would be enhanced naturally.  This is one breakthrough to improve the work efficiency of the mill.  Besides, according to different raw materials, to choose different machine combination.
Look, quartz is inorganic mineral, whose main components are silicon dioxide, and often a few of impurity ingredients such as aluminium sesquioxide, magnesium oxide and calcium oxide etc, appearing to be translucent or opaque crystal, generally ivory and hard.  Quartz is a kind of mineral resource with stable physical characters and chemical properties, crystal belongs to oxide minerals of three party crystal system , namely the lower temperature quartz (a-quartz), is the widest-spread mineral kind in mineral group.  Extended quartz also includes high-temperature quartz (b-quartz).  Quartz, also called silica, mainly is the raw material of quartz sand (also called silica sand) production, also quartz refractory material and fire ferrosilicon materials.  In addition, quartz is a common person name.
Quartz sand actually is silicate mineral, hard, wear-resisting, stable in chemical property, and main mineral composition of which is silica, the color varying with milky white, colorless, gray, hardness of 7, brittle, no cleavage, shells-shape breaking fracture, oil sheen, relative density of 2. 65, obvious anisotropy in the chemical, thermotical and mechanical properties, insoluble in acid, slightly soluble in KOH solution, melting point of 1750鈩? piezoelectric property. The role of quartz sand as industrial mineral raw material is of great importance, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.
Confronted with such materials as encounter, we should change strategy, but not to use the former grinding line.  Accordingly, quartz is very durable, we won't grind it, instead that, first roast it through the rotary kiln, later grind it by mill, on this way, the production efficiency will be enhanced dramatically.

One successful sandstone production line should own the following advantages including higher automation level, higher production efficiency, lower operation cost, large capacity, good shape, cube granularity of those finished products, and this production line nearly doesnt need the human beings except for the daily maintenance, opening and closing. The silica sand processing plant is made up of vibrating feeder, jaw crusher, impact crusher or cone crusher, vibrating screen, vertical shaft impact crusher and so on, which can make one successful production line by adding the belt conveyor.
The higher requirement of our nation on energy saving, environment protection, consumption lowering boosts the popularity of those advanced new type equipment with the above advantages, and whats more, the cost of those equipment are being decreased with the progress of our national industrial expansion scale and technology, so the first choice of the mining investors is to choose the energy saving equipment with good quality and competitive price, and that is the reason why more and more mining machinery pay more attention to the researching and development on those high efficiency, energy saving equipment.
Even though our natural resources are fruitful, the exploration level should be improved and increased.  Those related national policies advocated by our government also help the requirement on the technological aspects of the mining exploration reach one top level, which not only reveals the emphasis of our nation on mining exploration, but also increasing the market demand, so the above on can show that this is one good development opportunity for mining machinery.

The scrap material crushing equipment not only includes hammer crusher, the other crushing equipment is also applicable to solid material processing.  The jaw stone crusher machine is one of the most commonly used medium size stone crushing equipment.  With the characteristics of simple structure, low cost, simple operation, strong and durable and easy maintenance, it has become the most widely used crushing equipment.  Single toggle jaw crusher can be used for crushing operations of various hard ores and rocks, especially suitable for rough crushing operations in large and medium-sized mines as well as the processing industrial waste materials.
According to the swing of jaw plate, jaw crusher can be divided into several types: that is, simple type, complex type and compound type.  A simple swing type jaw crusher relies on the jaw plate, so as to achieve the good crushing effect of materials.  And complex machines need to do more to the orientation movement of jaw plate, which can carry out multi crushing angle of materials.  When jaw crusher is working, the motor drives the eccentric shaft to rotate through the belt wheel, so that the movable jaw will move closely and leave far away from the fixed jaw periodically.  Through the squeezing, rubbing, grinding and other multiple crushing of materials, the material will be crushed from big to small, and then gradually fall off until discharged from the discharging mouth.
The characteristics in the processing of solid material for jaw crusher is that its structure and operation principle are simple, easy manufacturing, convenient maintenance and its crushing ratio is 3-10.  At present, it has already applied in several metal and furniture recycling plant, and the effect is very obvious, which is the head of solid waste crushing equipment.  Our company is one of the most reliable single toggle jaw crusher manufacturers in China, which has many years of jaw crusher production experience.  We have high efficiency jaw crusher for sale with complete models.  When it comes to jaw crusher price, we have lowest quotation with highest quality.

With the construction of domestic infrastructure projects, the mining industry and the related industries have the board developing space.  The promulgation and implementation of various policies promote the quick develop of the national construction, which greatly stimulates the market demand on the sand aggregates.  Driven by the market demand, the sand production line got the rapid develop.  Under this circumstance, the mobile stone crusher produced by SBM has been widely used in many fields.
The mobile stone crusher plant is also named stone crusher.  The performance about mobile stone crusher plant: with the extrusion, flerry, bent, impact, crush and other methods, the large pieces of rock will be crusher into small pieces by this machine.  The commonly used machine is jaw crusher, cone crusher, hammer crusher and the roller crusher.  In addition to these devices, the mobile stone crusher plant also needs the vibrating screen, impact crusher and the compound crusher.
Mobile stone crusher plant is the crushing machine which can crush the material with maximum particle size of 600-1800mm.  It is suitable for the coarse crushing process of medium hardness material in the cement industry, chemical industry, electricity industry and the metallurgy industry.  It also can be used in the fine and medium crushing process of the limestone, slag, coke, coal and other materials.  The compressive strength of the material should not exceed 1000MPA and the moisture content should be less than 15%.

Stone crushers are also called rock breakers.  They are quite popular machines in the mining machinery industry. The stone crusher plant like jaw crusher, impact rusher, cone crusher etc are famous among customers because of the countless advantages such as: low construction cost; high crushing efficiency; fine crushing and rough grinding functions; be able to crush medium hard and extra-hard materials; simple to operate, maintain and install etc.
So how do stone crushers complete the crushing process? The answer is:
1. Materials enter the crusher via the feed hopper and are divided to two parts.  Some enter the high speed spinning impellor through the distributor and the accelerated speed can be a hundred times of the gravitational acceleration.
2. Then the materials are thrown out from three runners at the speed of 60-70m/s and impact the falling materials from the distributor.  Then they come to the lining of the inner cavity and get bounced by the material liner to the upper end of the whirling motion cavity.  Then they change the direction to move down.
3. The materials cast from the impellor form a continuous material curtain.  In this case, the materials can experience two or more times of impacting and grinding processes.  The crushed materials are discharged from the bottom hole.
In the whole crushing process, the materials hit each other without touching the metal components directly.  They meet the material lining in order to reduce the pollution and prolong the service life of the machine.  The advanced air flow in the whirling motion cavity can effectively reduce the dust pollution.

For the effective crushing of ores, you should choose appropriate crushers according to the characteristics of the ores.  They are different in compressive, abrasion resistance and humidity, so their requirements of the crusher equipment effect are not the same. When the compressive strength of the ore is relatively weak, such as soft shale, rock salt, gypsum, chalk, anthracite, common marl, sandstone, conglomerate, broken cement stone soil and broken shale, it is not necessary to use the jaw crusher.  Hammer crusher, roller crusher, impact crusher, cone crusher and composite crusher are available.
There are some medium hard ore, such as clay rock, limestone, sandstone and unstable density marl.  Such kind of ores can use jaw crusher, hammer crusher, as well as roll crusher, counterattack crusher and hammer crusher, which has a wide optional range.
And for the solid, delicate and tough ores, such as quartzite, basalt, granitic rocks, quartz porphyry, sandstone, limestone, iron ore, quartz vein, conglomerate, magnesium ore, marble, dolomite, pyrite, siliceous shale, sandstone and shale.  The crushing machine with strong crushing ability should be used to crush such kind of hard materials, for example, jaw crusher.  If other crusher are used, it will cause great damage to the equipment.
From the water content of ore, if the humidity of the material is too large, the ores cannot be crushed by hammer crusher with grate for discharging materials, such as clay mixture.  For the brittle ore, it is not suitable for the grinding type crusher.  Otherwise the grinding process will products too much fine powder,this kind of ore should adopt impact crusher.

Just like many other industries, the sand washing industry went through the economic stagnancy and suffered from certain degree of negative influence in the past year of 2013.  In the new year of 2014, all industries are expecting a long range development with a new look.  Therefore, how will so many sand washing plant manufacturers think about the brand new plans of improving the products and services of the sand washing machine in the future? This has been the core problem that everybody will concern.  Here our company will take you to have a deep look at the future development trend of sand washers in the market.
As we all know, China is stepping into a new development transformation period that will realize the integrated development of a lot of industries.  Although these industries are developing in different modes, they must have something in common about the developing principle.  As a small branch belonging to the mechanical industry, the sand washing industry will naturally work normally in accordance with the unchanged principle.  The development of sand washers is restricted by two aspects: upstream industry and downstream industry.
Upstream industry: Factors like raw materials, steels market, and quality and price of functional components of sand washing machines are all having effect on the quality of sand washers.
Downstream industry: The main factor that influences the development of sand washing industry is the social demand of river sand, sea sand and artificial sand.  The development of the downstream industry directly limits the demand of sand washers in the long run.  As the supplier of building raw materials, the quantity and quality of the sand products are both affected by the development of construction industry.  The construction industry not only refers to urban building construction but has a wide range of many fields.
As our life quality is improved, the new village and city development will become an inevitable trend.  In addition, the government has paid more and more attention to strengthening the transportation construction and improving the residential living facilities so that large amount of sand will be needed.  Our company believes that sand washers can develop well in the market depending on not only the technology but also the product adaptability.  That means to grasp the developing trend will make a good future.

MONDAY JOBS POSTING / The newest jaw crusher explores unknown world
« on: March 23, 2019, 02:50:07 AM »
The newest jaw crusher manufactured by SBM is designed to explore the unknown world, such as mining exploration and crushing city building wastes.  The newest jaw crusher not only has the coolest appearance, but shoulders the important responsibility of uncovering the biggest mystery in the world. The pew jaw crusher is all equipped with a wedge-shaped nidificant adjusting device which is a simple, safe adjustment device with high speed.  The big eccentric shaft adopts forging stock for processing which make the PE series jaw crusher have outstanding reliability.
Jaw crusher plays an irreplaceable role in the rock crushing production, but at times, when the operational workers operate the jaw crusher, the machine is often difficult to start because there is starting dead angle for this crushing machine and it needs external force to drive the flywheel and turns the dead angle so that it can be started.  In this way, the smooth production of the crusher equipment will be affected.  As a result, how to eliminate the starting dead angle of jaw crusher becomes a major problem waiting to be solved.
On the other hand, in order to solve the practical problems in traditional jaw crusher, such as the environmental pollution and resources waste, the engineers and technicians of SBM make the base and the green-base as the research and development idea, thus significantly reducing the energy consumption and environmental pollution.  Seen from the current situation of jaw crusher, the weight of the machine manufactured by domestic companies is higher than that manufactured by foreign companies and the design of jaw crusher still focuses on peoples experience.

The high strength grinding machine as a new type of grinding equipment has been appreciated by users from all fields because of their energy saving feature. In the past, the high strength grinding machines are mainly used in the cement production line while at present they start to march into the metal mine industry.  Although some mining companies are using the high strength china grinding mill in the real production, we cant ignore that the promotion speed of the equipment in the metal mine industry is not so high.
Through the investigation and analysis of our experts, we find that the main reason resulting in the slow growth of the high strength grinding machine in the metal mine industry is the short service life of the grinders roller surface. We all know that there are many kinds of metallic ores with strong hardness and corrosive property which make the roller surface easy to be worn.  Once the roller surface is worn, its annoying for users to frequently maintain and fix the roller.  This case not only decreases the working efficiency but also increases the production cost.
Aiming to solve the above problems, the grinder research and development institute of our company has tried many ways to improve the working life of the grinders roller and to reduce the time of fixing and changing the wear parts. Our experts will speed up the pace of promoting the high strength grinding machines in the metal mine industry and we believe that the innovation will be the best way to change the current situation.

In the industrial fields of our country, the disposal of many types of raw materials and the recycling of industrial waste need ballast crushing machine, for this reason, crusher has very important position.  With the constant development of infrastructure construction and the constant acceleration of social development, the market demands for construction materials will increase, which will promote the fast development of the crusher industry.  Here the experts from our company will give an introduction to the influencing factors of the crushing effect of a crushing machine.
According to the introduction of the experts of our company, in the production process of a crusher, there are many factors influencing the crushing ability of the crushing accessories.  Besides human manipulation and the quality of the equipment itself, the property of the stone materials to be crushed is also one of the factors influencing the crushing ability of the crushing accessories.
1.  The hardness of the stone materials.  It is known to all that it is more difficult to crush hard ores, and the abrasion to the crushing accessories will be more serious.  Many crushers crush the stone materials through constantly abrading its accessories.
2.  The humidity and stickiness of the stone materials.  Generally speaking, the drier the stone is, the easier the crushing process will be which is why there is hot air used for drying the water in the materials in the grinding mill.  In the meantime, the materials with high water content and big stickiness will block the machine in the crushing and transportation process, which will reduce the crushing efficiency of the equipment.
3.  The discharging granularity of the stone materials.  Sand particles with high fineness needs longer time of crushing.
4.  The elementary composition of the stone materials, which mainly refers to the fineness of the stone materials.  If there are many impurities in the stone materials, the quality of the final products and the crushing capacity of the equipment will be influenced.
5.  The abrasion resistance of the quick-wear parts.  The higher the quick-wear parts are, the higher the crushing capacity of the crushing equipment will be.

MONDAY JOBS POSTING / The design requirements of crushing plant
« on: March 20, 2019, 09:17:18 AM »
If the crusher needs to work indoors instead of outdoors, in this case the crushing plant has to meet the required standard, generally considering from several aspects as following.
1.  The Ore Processing Capacity
The ore processing capacity is one of the important indicators of crushing plant.  Sufficient ore reserves make sure an effective and constant crushing work.  It provides the quartz grinding plant with ores of qualified particle size and sufficient amount, which ensures the normal conduct of crushing.  Plenty of ore reserves can reduce the idle of equipment and get the best economic benefits within the same time.
2.  The Final Product Particle Size
The particle size of the finished products is another important indicator of the crushing plant.  If the particle size doesn't meet the corresponding requirements, it not only affects the economic benefits of this step, but also has a direct influence on the next phase of grinding.  If the final particle size is bigger, it would increase the cost of grinding.  Therefore the crushing strength must be controlled in a reasonable range, both to ensure the crushing efficiency, and make a good preparation for the next step of grinding.
3.  The Consumption of Sand Processing Plant
In addition to the consumption of the main equipment for example the crushers, there still exist other auxiliary consumption, such as electric power, steel , lubricating oil, water and so on.  These kinds of consumption differ as the change of ore particle size, mineral composition, types and hardness.  Among them, the consumption of electricity is in the most prominent.
We should take energy consumption into consideration in addition to guaranteeing the normal work of crusher machines, and try our best to reduce energy consumption, which is an effective way to save costs, and improve economic benefits.

Crushing and grinding technology plays an important role in the development of the national economy, and also it plays a significant role in promoting the development of the society. Crushing and grinding of material is the necessary link of the solid mineral process, it is the first step of producing industrial raw materials.  With the large number of mineral resources exploitation, colored, black and metallurgical mineral resources are increasingly becoming depleted, the amount of mining is greatly increasing, and the amount of needed gravel is rising, which makes marble quarry equipment operation become more and more important.
According to statistics, by the end of 2010, the total mineral resources of China has proved accounts for about 12% of the world, it ranked the second place in the world, and 171 kinds of minerals have been found.  In addition, the steel production, coal production, non-ferrous metal production and cement production in 2009 ranked the first place in the world; this is the tremendous achievements that China has got in the part of mineral resources exploration, development and processing.
Comprehensive utilization of mineral resources, technology and industrys rapid development, not only provide a broad space for the crushing and talc grinding mill, likehammer crusher,jaw crusher, and so on, but also put forward higher requirements to them. Because the bonanza amount continues to reduce, but the lean ore is increasing, which makes the crushing difficulty of materials increased.  How effectively separate the useful minerals, reduce energy consumption and improve the performance and production efficiency of mining machinery equipment, all these are the common problems that companies is facing.
Take jaw crusher for an example, it is the oldest equipment, its development is obvious.  The technological advance of the jaw crusher is mainly reflected in four aspects: structure, cavity type, parameters, and institutions.  Through the improvement of the above aspects, they make the key performance parameters of the crusher greatly improved, so the future development of it is also unstoppable.

Jaw crusher is often used for crushing limestone.  Limestone is an important kind of ore, which is widely applied to the industrial production and daily life.  In the mining machinery industry, the most powerful limestone crushing equipment is jaw crusher.  As the earliest quarry crushing machine, the working principle and structure of jaw crusher are the most simple and convenient to operate.  The appearance of jaw crusher has lays a solid foundation for research and development of cone crusher, hammer crusher, impact crusher and single stage crusher, which provides the reference for the later development of crushing equipment.
From the appearance to the promotion, jaw crusher has been integrated into the production of various industries, which has brought different changes for the development of industrial processing.  At present, jaw crusher not only got the recognition of each industry, but also provides convenience and benefits to the customers.  Jaw crusher is the hot product of Fote Machinery, which has great superiority in processing of limestone.  Fote jaw crusher can significantly improve the work efficiency and overcome the traditional shortcomings of crushing equipment, which plays an important role in driving the rapid development of the limestone industry.  Jaw crusher has big crushing particle size of 1000*1200mm in crushing limestone, after the initial crushing, it can be crushed into the required granularity, which can replace the traditional second stage crushing.  It is professional for improving limestone crushing efficiency and simplifying the production process, which greatly saves the construction investment and production cost at the same time.  In addition, jaw crusher effectively solves the supply shortage of original limestone, which plays an important role in the limestone production line.
As experts analyze, for investors, the future crusher equipment in the international market is optimistic about the direction of the future, and the basalt crushing machine will also develop in the green environmental protection, energy saving and high efficiency in the trend.  Later, crushing machine industry in China will usher in a major development tide.  The jaw crusher produced by Fote Machinery has many types, for example PE jaw crusher, single toggle jaw crusher, double toggle jaw crusher, small crusher and so on.  Fote jaw crusher has advanced structure, reliable quality and preferential price.  If you are interested, please chat with us online to get our latest quotation.

There is one new phenomenon appearing in the field of mining machinery, that is that more and more manufacturers begin to pay more attention to the following aspects: market boosting, brand building, culture establishing.  A lot of manufacturers choose the open type development tactics in order to realize the expansion of image and brand improving by enhancing the advertising strength on mining equipment market.  That is to say, who can grasp the market tendency can achieve the customers resources in this new developing period.
Our crusher manufacturing industry develops quickly in recent years, and the industry size also is becoming bigger and bigger, so those manufacturers begin to transfer their market to the overseas.  We all know that there must be some advantages on price, quality, service if we want to occupy one higher percentage in the whole international market, which can help us realize the expansion on the international market space.  That is the reason why our national crusher manufacturers still should insist on expanding the homemade demanding, continuously improving the technological percentage on the products, and learning the advanced manufacturing craftsmanship at the same time in order to compete with those strong rivals by those excellent products.
The only thing that our national crusher manufacturers should try their best to enlarge the strength on the researching and development on new products, to improve the production efficiency, to develop the automatic equipment, and then reach the international standards, which can greatly help us increase the market occupation of our national crushing equipment.

The current situation in the sand and stone material industry in our country is that the artificial sand maker technology in the market is still relatively backward, as a result of which, large quantities of stone and sand material plants cannot provide finished sand with high quality.  For this reason, even the mixing equipment has excellent performance; the mixed concrete is low in quality.  This problem is very serious, as it will directly influence the overall service life of the buildings in our country.  To change this situation, it is imperative to improve the overall innovative level of sand maker technology and at the same time, sand plants should pay attention to the technical strength of the production company when choosing sand maker brand.
To improve the quality of sand aggregate, we have to do a good homework in the technology of sand maker.  At present, the technical level of the sand maker manufacturing companies is different, for this reason, to improve the overall technical level of sand maker in the future, domestic companies need to further increase the investment in technology research and development and applied technology of the equipment.
The improvement of sand maker technology needs unremitting innovation.  Through constant innovation, our company has grasped world advanced sand maker technology.  The new generation of VSI5X sand maker researched and developed by our company represents the most latest artificial sand making technology in domestic market.  Our VSI5X series of vertical shaft impact crusher has passed the test of national mining machinery quality supervision test.  The technical level of sand maker directly influences the quality of sand aggregates.  Faced with future development, the sand maker manufacturing companies in China are required to make innovations, only by this can we gain more development opportunities and go further.

The developing history of jaw crusher is so long beyond our imagination, and the structure of crushing machine in such a long time gets more and more improving and perfecting.  Even though the application of jaw crusher function is so wide, there are some defects existing in the mining machine, and that is the reason why the mining experts are trying to improve the working efficiency of jaw crusher and its performance characteristic in order to satisfy the various demanding on the crushing results of the customers.  And then some advanced jaw crushers appears in the presence of the human beings.
There is one designing institute, which ever researched one jaw crusher with the dual chamber and compound pendulum, and the design can help to reach the two purposes, one is to improve the working efficiency, and the other is to decrease the load on the crushing machine by relying on the light weight of this machine.
The researching on the various jaw crushers of mining experts has achieving much progress at this right minute, which can make a difference to the whole development of mining machinery and to boost the speed of mining progress, but which cannot be applied in such a wide scope, and the reason can be rested on the shoulders of the mining customers who still choose to use the traditional jaw crusher.  The only road for the whole national mining machinery is to innovate and update the mining sand maker as soon as possible in order to occupy the big market share of mining area.

MONDAY JOBS POSTING / The existing problems of the quarry
« on: February 28, 2019, 03:33:36 AM »
The mining of the deposit includes two categories: underground operationor open-air operation.  The operation that there is no natural lightingand works in the underground is called the underground operation and thequarry is also called underground quarry.  The quarrying equipment in the naturallight is known as the outdoor quarry.
The sources of the ecological damage of the quarry can be divided intotwo categories: human destruction and natural destruction.  Both thehuman destruction and natural destruction will eventually lead to thedestruction of vegetation, the bareness of the land, soil erosion anddeterioration of the ecological environment and the natural landscapewill suffer the destruction and a series of serious ecological andenvironmental problems.
In the entire mining process of the quarry, when it rains, it will makethe soil that has lost the vegetation protection and soil conservationbe further eroded by rain, causing soil erosion.  If it encounters theheavy rain and poor weather conditions, it is most likely to cause themudslide, leading to the serious soil erosion and deterioration of theecological environment.
