Stone sand making equipment Lime and limestone are used as building materials in large quantities, and the development of silica sand washing is also going to the road of energy saving and environmental protection. It is not difficult to see the continuous introduction of high-tech crushers from various sand washing machine manufacturers. Many manufacturers are aware of this problem, which is common as a raw material for the cement production process industry and an important raw material for many industries. Limestone can be directly processed into stone and fired into quicklime. This is a good thing, which will make China's sand washing machine industry have its own advantages in the constant competition, but this is also a very difficult road. To select mining equipment for limestone production and processing, first of all, what is the production, such as the use of two or three-stage jaw crusher for roadbed stone. What crusher should I use for the limestone production line? Of course, there are a variety of configurations, so that the economic strength can be comprehensively considered according to the purpose.In the process of production and processing of limestone, the research and development of sand washing machine is a very difficult task. It requires a lot of money, manpower and material resources. It also needs the experience of developing sand washing machine in the past. These things can all be combined to make a breakthrough in the development of new sand washing machine. The crushing machinery is the main production equipment. Different types of crushers can be used to produce limestone raw materials with different particle sizes and different uses to meet the various needs of different industries. The crusher series equipment commonly used in the limestone production line produced by Luyi Heavy Industry includes: Although China is now a big country in the production of sand washing machine, there are many manufacturers of sand washing machines, different in size and size, in terms of technical level. There is also a big gap,1. The sliding groove of the lining seat and the machine base is worn. The asymmetry caused by the arc depression state causes the lining plate seat to be non-parallel in the groove, and the phenomenon of falling off occurs. At this time, it is necessary to make the lining plate seat cooperate with the chute to repair the work, and ensure that the half-seat seat moves in parallel in the groove. 2. The thickness of the positioning slider welded on the base is uneven. The measured error is caused, so that the contact between the adjusting wedge and the base is not vertical, causing the lining to fall off. Ball Milling Mechanism This situation should be repaired by the slider of the base to ensure that it can rise or fall vertically with the lining seat. Third, the tie rod is damaged or the nut is released. It is necessary to replace the tie rod and retighten the nut of the tie rod. 4. The hardness or toughness of the crushed material is outside the specified range. In this case, the broken material that does not meet the specifications should be cleaned out. 5. The motor wiring position is reversed. Connect the motor wiring position of the crusher correctly. 6. The lining plate is displaced. The position of the lining should be adjusted in time.

Limestone has high utilization rate in crushing and is abundant in reserves all over the country. Its main component is calcium carbonate, which can be used as high-quality stone in construction, railway, road and other fields. And because of its low mining cost, limestone has been favored by many mining industry investors. The choice of crushing equipment for limestone mines needs to be carefully considered at the beginning of the investment. In the limestone production line, how to choose equipment to meet our production needs, and profit margins in the later stage?

The limestone production line consists mainly of feeders, jaw crushers, impact crushers, vibrating screens, sand making machines, etc. Limestone is relatively low in all commonly used crushed stone materials, so it is used in several types of equipment. Of course, if the output is large and the production demand is different, the cone crusher is also a "library" for crushing limestone. The limestone has a large block shape at the beginning, and can be uniformly fed into the jaw crusher through the feeder. After the initial crushing, it passes through the conveyor to the stone crushing plant, and is processed by medium and fine crushing, and sieved through a vibrating sieve. Therefore, the limestone production line has less initial equipment investment, and the price of these equipment is lower than other equipment, so the profit margin is still relatively large.

Every different production line, no matter what stone is broken, the demand for stone is different. In addition to the demand, the size of the site, the chemical composition of the stone, and the budget for the cost are also different. Therefore, when selecting equipment, consider To all aspects of the problem.


The jaw crusher has always been an important crushing device for the coarse crushing process in the stone production line and the sand production line. Since the feed port of the jaw crusher is large, it is a primary crush in the crushing production line, which shows his importance. The traditional PE series jaw crusher is a toothed plate extrusion type of round-trip crushing, and the broken material can only meet the requirements of entering the impact crusher and fine crusher for crushing production. Therefore, he is usually in the stone production line. The highest point is broken.As a new generation of high-performance crusher, jaw crusher surpasses traditional E-break in performance, maintenance cost and structure, and can be widely used in metal and non-metal mines, cement, construction, sandstone, metallurgy and other industries. PE series high-energy rupture is used in the production process of building gravel and machine-made sand, especially when crushing hard materials such as basalt, it has higher production efficiency and lower running cost than traditional smashing.According to the principle of the PE series jaw crusher, a buffer spring is added to the back, so that it can play the role of buffering the pressure during the production, which further increases the particle size and the degree of extrusion, if it is in production. When the discharge is too large, only the adjustment of the bolts behind will strengthen the discharge particle size of the entire stone production line to alleviate the pressure of the secondary crushing to achieve the overall production efficiency improvement, and the discharge granularity is uniform.


Energy-saving and environment-friendly production equipment, under the promotion of environmental protection, energy-saving and low-cost social policies, is not only the development direction of the ultra-fine mill industry, but also the main direction of the entire social and economic development. This not only requires the improvement of the production process of related industries, but also requires solid and effective technical support. It can continuously research and develop and improve the bentonite processing plant equipment, and strive to achieve a win-win situation between ecological protection and economic benefits in the production. . The energy-saving and efficient of the ultra-fine mill is the current king.Ultra-fine mill is an important equipment for industrial raw materials and energy production. Its efficiency will become an important development factor in the energy field. With years of development, it has gone through extensive development relying on the advantages of cheap labor and sacrificing the environment. In the stage, in line with the international trend of low-carbon economy, the rapid development of the ultra-fine mill industry market will usher in the spring of development.The purpose of recycling mineral resources, saving energy, extending the industrial chain, and expanding the vertical extension of the environmental protection system, is the performance of the kaolin processing plant in the mining machinery.

It also conforms to the theme of contemporary green low carbon.With the continuous development of the economy and the continuous innovation of the industry, the demand for ultra-fine mill equipment in China is constantly increasing, and the increasing number among manufacturers makes the competition between China's mining machinery industry more and more fierce. The demand for products is constantly changing, and the changes in these requirements will be an important factor in guiding the development direction of the ultra-fine mill industry. Among the whole industry manufacturers, only Shanghai SBM ultra-fine grinding machine is energy-efficient and efficient.


Friends who are in mineral processing, cement, and mining know that the industry is now a very competitive industry. The same is true for machinery manufacturers, who can disregard customers for the purpose of selling machinery. And we are different in the world, we are in this industry and decided to serve customers, all for customers. Shisheng people serve customers with the principle of “truth, real goods, and true price”.As we all know, the most widely used in the conventional grinding operations of concentrators, cement plants and mines is still cylindrical Calcite mill Introduction or tube mills. The use of these as ultrafine grinding of ore (or material) (usually referred to as ultrafine grinding) is quite difficult and uneconomical due to:First, the pulverization strength of such ultra-fine mills is determined by the acceleration of gravity. Conventional ball mills use the principle of gravity to grind, so the strengthening effect of the material grinding process is limited by the acceleration of gravity, because the ball (tube) mill grinding material and gravity acceleration is generally 1g. The centrifugal or centrifugal ball mill with ultra-fine grinding using the principle of centrifugal force generally has a centrifugal acceleration higher than that of a conventional ball mill, which is more than 10 times, so the material grinding effect is greatly enhanced. For example, the centrifugal acceleration of a planetary ball mill is 15 times the gravitational acceleration g, and the vibration acceleration of a vibratory ball mill when grinding materials is generally 8 to 1 Og.Second, the energy efficiency of such ultra-fine mills is very low. This is because the grinding action of the conventional ball mill is limited by the acceleration of gravity, so that the strengthening effect of the material grinding is hindered, the grinding energy cannot be effectively utilized, and the grinding efficiency is extremely low. In conventional grinding, the energy used to create a new surface is typically less than 1%. The grinding efficiency of the centrifugal tower bentonite mill for finely grinding uranium ore is 4-8 times that of the conventional ball mill, and the efficiency of grinding the rock salt is 15 times higher than that of the ordinary tube mill.

There are many kinds of micro-grinding materials, which are used in the production of various materials. Micro-powder grinding is a commonly used grinding equipment. In the process of grinding, due to various natural factors and human factors, micro-grinding The fineness of the finished product sometimes appears to be unqualified. What are the causes?

Micro-grinding is different for different ore materials. Its particle size and hardness are also different. When  bentonite mill and grinds it, it also has a certain impact on the production capacity of the equipment. Under normal circumstances, if The hardness of the ore material is high, the particle size is large, and the grinding difficulty of the material is increased by the micro-grinding, which not only affects the yield but also affects the fineness of the finished product.

During the operation of the micro-grinding, the rotation of the reducer drives the rotation of the central shaft. If the rotation speed of the central shaft is too large or too small, the grinding time of the material will be shortened, so that in the case of insufficient material grinding, This will result in a larger fineness of the finished product.

In the process of grinding the material, the Calcite mill Introduction is driven by the blower and enters the analysis machine for screening. If the wind speed of the blower is too large, the material that does not meet the production requirements will enter the dust collector, thus making the finished product granularity. Too large, affecting the fineness of the finished product.

In addition to the above problems, the analysis of the blade of the machine, the opening and closing of the classifier, and the feeding mode of the worker are also important factors affecting the fineness of the finished product. Therefore, when using the micro-grinding mill for grinding production, we must pay attention to the details of all aspects to ensure the fineness of the micro-fine grinding products.


The technical performance of the SBM cone crushers is further improved, using advanced hydraulic technology, which is more efficient and safer. In the configuration of the equipment, hydraulic starting devices, hydraulic adjusting devices, hydraulic safety systems, hydraulic transmission devices, and the like are added.The hydraulic cone crusher has support according to the upper and lower ends of the main shaft, can withstand the crushing force of iron ore and larger stroke, and the special crushing cavity shape suitable for the lamination principle makes the broken iron ore have higher crushing. Efficiency, after the equipment is upgraded, the crushing stroke, crushing speed and crushing cavity shape are combined to produce iron ore, which is 35%~60% higher than that of the old-fashioned cone. The stone is reduced and the grain size is more uniform. The new cone crusher overcomes the contradiction between the output and fineness of the traditional cone crusher, adopts the medium-fine crushing replacement and the laminating crushing principle of various cavity rows, so that the proportion of cubes in the broken finished product is obviously increased, and the needle-like stones are reduced. The grain size is more uniform and the output is stable, which fully meets the production needs.Iron ore processing generally includes exploration, mining, head breaking, second breaking, screening, fine crushing, dry selection, transportation and other processes. Iron ore crushing is particularly important. The finer ore size that usually enters the dry selection, the iron ore is included. The higher the proportion of dry selection, the most economical production method, the maximum dry iron ore dressing rate, and many types of fine crushing equipment, such as impact crusher, jaw crusher, etc. Different, the applicable links have limitations. The new cone crusher overcomes many difficulties and is used for the fine effect of iron ore fine crushing. The hydraulic Cone crusher in germany is optimized in combination with the speed, stroke and crushing cavity type to achieve inter-granular lamination crushing, which significantly increases the output and greatly improves the shape of the product.SBM heavy work is a professional crusher equipment and mineral processing equipment manufacturer. The main products are roller crusher, jaw crusher, impact crusher, impact crusher, hammer crusher, etc., to provide more efficient customers. High-quality crushing equipment products and sincere and perfect services have made greater contributions to the development of crusher equipment industry in China.

The fineness and yield of the material depend on the air volume adjustment of the micronizer. The air volume and the feeding amount are matched. The air volume is the head and the feeding amount is the tail. The two must match, and the amount of the T130X Reinforced Ultrafine Mill feeding should be increased. The amount of air pulling must be short because the drying effect of the material and the material are in the micro-grinding. The speed of the flow depends on the amount of wind. The air volume of the micro-grinder is a factor affecting the output. The lack of air volume will bring about the lack of dusting capacity. If the air volume is too large, it will increase the load of the fan and the load of the dust collector, and will also affect the quality of the finished product. Therefore, different materials, different yields, and different control results require different air volumes to adapt.

The large air volume will bring a large load to the dust collector. If the pressure difference of the dust collector is large, it means that the dust collector is overloaded, which will affect the normal operation of the dust collector. Therefore, while increasing the air volume and increasing the output, the capacity of the dust collector should also be considered. The returning material can also reflect the air volume. If there are too many fine powders in the returning material, it means that the air volume is insufficient, and at the same time, the dust outside the dolomite after grinding will be increased, and the output will be affected. In the case that other control parameters are unchanged, the control result of the grinding material is low or the pressure difference of the main dust collector is too large, indicating that the air volume is too large and should be properly adjusted.

The wear of the buy stone crusher during use is inevitable, especially in the use of the crusher. Due to the particularity of its production work, the wear is very obvious. In the case of rapid wear and damage of the equipment, the damage is serious. It will seriously affect the progress of the entire production process, which is a significant reduction in the production efficiency of the production line. The wear of crusher equipment is mainly divided into the following two aspects.

First, natural wear

It usually refers to the change of the geometry and size structure of the instrument components caused by the mutual friction between the various parts of the machine during the normal use and operation of the machine. This part of the wear is usually slower and the hazard will not be caused in the short term.

However, due to the wear of the device, the mechanical contact gap between the components is increased. After a long period of wear, the components that should be combined to work together, the gap is increased due to wear, and the joint cannot be well combined. This will seriously affect the production efficiency of the crusher equipment. At the same time, if the wear device cannot be replaced in time, it may even cause damage to other components, resulting in more damaging damage to  tantalite mining>.

Second, premature wear

Mainly because of the unreasonable structure of the machine itself, the inferior quality of the materials used by the individual zero devices, the substandard quality of some components, and the incorrect installation and wrong equipment operation.

After multiple analysis, it is concluded that the damage caused by the crusher in the process of heavy industrial equipment is relatively large. Therefore, in the process of using the crusher, we need to timely maintain good maintenance and bad for all kinds of wearable parts. Replacement of the device. Only when we find the problem better in the process of use and deal with it in time can we ensure the higher efficiency and normal safe operation of the crusher.


With the rapid development of national infrastructure and industrial construction, the types and models of crushing equipment are also increasing. The increase in the types and models of crushing equipment also allows users to have more choices, and also allows customers to face the situation of not knowing how to choose the right crushing equipment when selecting crushing equipment. So how do you choose a buy stone crusher that meets your own production needs? Take a look at the following three points:1. Characteristics of stoneThe softness, mud content and water content of the stone are very important data. In addition, the equipment should be selected according to the maximum particle size of the stone. If the material is small, it can directly enter the secondary crushing equipment. If the hardness of the broken stone is too large, such as granite, basalt, pebbles and other stones, you can use the jaw crusher or cone crusher to crush; the smaller hardness stone, such as limestone, can use the concrete crushing machines for the second time. broken. Minimize the wear of consumables such as dental plates, which saves production costs and increases production efficiency.2, the requirements for product qualityThe customer's requirements for the granularity and stone shape of the finished product also determine what kind of crushing equipment should be selected. If the size of the crushed sand is different, a screening device is also required for screening. In many projects, if the soil content of sand and gravel is too high, a sand washing machine is needed to add a sand washing process.3. Use of the finished productThe construction requirements of various national highways, railways, bridges, etc. for sand and gravel aggregates are also different. It is necessary to arrange the stone production equipment according to the configuration of the finished stone of the user. For example, highways, high-speed rails, dams and other projects have higher requirements on stone materials. If such construction uses cracks and sharp corners, the risk of collapse will be increased. The stone material is usually treated with an impact crusher to meet the standards of fine materials.
