Sand making machine is also called impact crusher. SBM combined with the actual situation of domestic sand making production, developed high efficiency and high quality crushing equipment with domestic and international leading level. VSI Crusher can not only provide high-quality aggregates for highways, railways, high-rise buildings, municipal engineering, hydropower dam construction, port terminals, concrete mixing plants, etc., but also become more and more metal ore crushing, quartz sand production , The mainstream equipment in the fields of steel slag processing, etc., so it has undoubtedly become the core equipment in the field of machine-made sand and stone shaping. The characteristics of SBM sand making machine, the sieve plate adopts a unique spring retreat mechanism, which is convenient, reasonable, safe and reliable. HXVSI series high-efficiency vertical shaft impact crusher (sand making machine) adopts spring constant force adjustment to make the crushing force constant for a long time. Maintenance is simple, just lift the upper box and open the lower box, so maintenance is extremely convenient. The multi-layer three-channel discharge device is adopted to discharge the materials that meet the requirements in time, extend the life of the wearing parts, and greatly increase the output of the table. The rigid solid rotor body is used, which has large rotating inertia and strong striking force, which is not easy to cause equipment jams. With plastic function, the product has a square shape and a large packing density. The equipment is small in size, easy to operate, and easy to install and maintain. While the output is high, the energy consumption is small and the crushing ratio is large. The working principle of the SBM sand making machine. During the work of the sand making machine, the material enters the machine from the feed hopper, and the material is divided into two parts through the distributor, and a part enters the high-speed rotating impeller from the middle of the distributor. The interior is rapidly accelerated, and its acceleration can reach hundreds of times the acceleration of gravity. Then it is ejected from the three uniformly distributed flow channels of the impeller at a speed of 60-70m / s, and first impacts with a part of the material that has fallen from the surrounding of the distributor Crushed, and then impacted on the material lining in the vortex branch cavity together, rebounded by the material lining, impacted diagonally upward on the top of the vortex cavity, and changed its direction of movement, deflecting downward movement, the material emitted from the impeller flow Form a continuous material curtain. In this way, a piece of material is subjected to two or more chances of impact, friction, grinding and crushing in the vortex crushing chamber, and the material that is crushed later is discharged through the lower discharge port.
The structure of butt joints of VSI Crusher is various. There are fork lug type joints, frame type joints, chute joints, pulley skateboard joints, hinge joints and so on. The structure of the joint hole is also varied. Some joints are divided into a base body and a bushing. The bushing is installed in the base body; some joints have bearings in the base body, and the bearings are installed in the base body; some joints do not have bushings and bearings, and directly connect the hole shaft. The connection form of the joint and the component structure is also various. Some joints are integrated with the component structure. The joint itself is a part of the component structure: some joints are separated from the component structure, and the joint is connected to the component structure through a connecting piece. Some joints are simple in structure and convenient for docking; some are complex in structure and difficult to dock. Some joints are simple in connection with the structure and have a design compensation function. Appropriate position adjustment is allowed when the components are docked: some joints are complicated in connection with the structure and do not have a design compensation function, which requires high position accuracy of the joint. In short, the joint structure of the impact crusher has a variety of structural forms, and structural designers often care about the structural requirements and use requirements of the component joints, but do not care or pay enough attention to the finishing requirements of the component joints, making it difficult to finish the components. Or it cannot be finished.
With the increasing demand for artificial sand and gravel, the market demand for sand making machines is getting higher and higher. How to increase the sand output of sand making machine? Sand making machines have a wide range of applications. For different processing materials, their hardness, viscosity and humidity are different, and the sanding capacity of the sand making machine will also be different. The harder the material, the more difficult it is to process, and the equipment wear is also very serious, resulting in a slower sand making speed and a natural reduction in sanding. Conversely, the lower the hardness of the material, the more polished. Materials with higher viscosity tend to adhere to the inner wall of the sand making machine during processing. If it is not cleaned in time, it will seriously affect the output and efficiency of the sand making machine, thus affecting the amount of sand making. If the water content of the processed material is relatively large, sticking is also likely to occur, which may cause long-term blockage problems, thereby reducing the sand making capacity of the sand making machine and increasing the amount of sand made. Different types of sand making machines have different amounts of sand making, energy consumption, efficiency, dust and so on. Different models have different applications. The quality of the sand making machine itself is a key factor affecting the amount of sand making. The high-quality sand-making machine is not only energy-saving and environmentally friendly, but also can easily achieve the sand output that users expect. In addition, the quality of the sand making machine produced by the professional production plant is more reliable, the wear resistance is better, and the service life is longer. It can meet the requirements of users in terms of output, efficiency, energy saving and environmental protection. The operation and maintenance of the sand making machine will also affect the sand production of the equipment to a certain extent. Even if the good sand making machine equipment is not operated correctly and is not maintained regularly, it will damage the equipment parts, shorten the service life and reduce the output. Therefore, regular maintenance can not only increase the sand output of the sand making machine, but also extend the service life of the equipment.

Environmental protection requirements are becoming more and more strict during construction. Sand and gravel production line manufacturers must not only ensure the quality of finished products but also ensure that the environmental protection standards are met in the production process in order to be qualified for production. The main pollutant in the operation of the Sand Making Machine is dust, and the establishment of an effective dust removal system is the key. At present, the dust removal system is mainly composed of water spray dust removal and bag dust removal. The function of water spray is to generate less dust, and the function of the bag dust collector is to collect the generated dust. In the aggregate production line, a water spray device is generally installed in the head hopper of the unloading bin and each transfer station. If a steel structure greenhouse is used for the storage of finished products, a water spray device is also provided. The design points of the water spray device are: the nozzle position and quantity are designed reasonably, the water volume can be adjusted, and the water pressure is guaranteed, otherwise the dust reduction effect is not obvious and it is easy to block the screen hole of the vibrating screen and affect production. The design points of the bag dust collector are: the specifications, quantity and collection duct of the bag dust collector should be designed reasonably, and the dust collection dust must be set up in a separate storage store and not returned to the production line to avoid secondary dust generation downstream. In addition, in the design, as much as possible to reduce the drop of each feeder not only reduces a certain construction cost, but also a means to reduce the generation of dust. The system flow of the gravel production line should be determined according to the specific environment, material characteristics, product shape and market demand. For the product shape, the cone crusher is better than the impact crusher, and the impact crusher is better than the hammer crusher. The use of closed steel silos (or concrete silos) for storage is more environmentally friendly than steel structure sheds, and is preferred in areas with stricter environmental requirements. In recent years, environmental protection has become stricter and stricter, which has increased the production costs of sand and gravel production enterprises. However, the achievements have been significantly reduced, and the number of blue sky and white clouds has increased. Sand and gravel manufacturers should also change their minds and adapt to the situation. They should see that the government has changed from the previous encouragement to the mandatory implementation of environmental protection construction. Environmental protection production. Most of the companies that do not meet or produce serious pollution have been shut down or ordered Require self-inspection to stop production. Therefore, factories and enterprises, including sand and gravel production lines, should take advantage of this opportunity to complete the transformation, consider for a long time, and realize a sustainable industrial operation mode.

After the classification of the analyzer, the fine powder meets the airflow and enters the large cyclone collector through the pipe for separation and collection. It is then discharged through the powder tube to obtain a usable finished product. The airflow is drawn into the blower through the return air pipe at the upper end of the large cyclone collector. The entire airflow system of this machine is closed and circulating, and it circulates under positive and negative pressure.
In recent years, due to advances in powder processing technology, gray calcium powder products with a fineness of 600 mesh or higher have been available on the market. So how to choose hammer crusher and slag vertical roller mill for processing ore and slag? The following SBM heavy machine recommends comprehensive processing equipment for you. SBM heavy machine ore high pressure mill is suitable for crushing various ore chemicals Grinding of non-metal raw materials such as raw materials, such as iron ore, pulverized coal, blast furnace slag, desulfurizers for power plants, coal injection by boilers, white ash, feldspar, quartz, gypsum, barite, limestone, ceramics, Non-flammable and explosive mining, metallurgy, chemical, building materials and other industries with more than 280 materials with high Mohs hardness of 9.3 slag and no more than 9.3 hardness and humidity of less than 6%. Adjustment (fine 1000 mesh). The processing fineness of SBM heavy machine slag vertical roller mill is finer than that of high pressure mill, and the fineness can be adjusted arbitrarily between 300 mesh and 3000 mesh. The residue after ore beneficiation or smelting is called slag. The slag is widely used after being processed by slag vertical roller mill equipment. In industrial production, slag plays an important role, especially some major factories. The slag is made into slag cement, slag fine powder, slag powder, slag portland cement, slag cotton, blast furnace slag, granulated blast furnace slag powder, copper slag, and slag vertical roller mill. Saved energy. The main component of gray calcium powder is a mixture of Ca (OH) 2, CaO and a small amount of CaCO3. It is a refined product of lime. It is a natural high-quality limestone with CaCO3 as the main component. It is selected, partially digested, and then pulverized by a high-speed air-selection hammer mill, and its appearance is white and delicate. The working principle of SBM heavy machine slag vertical roller mill: The raw slag of the slag vertical roller mill enters the feeding silo via a grabber, and after measurement, it is fed by a conveyor belt to a screw feeding device and fed into a ZJTL roller vertical roller mill. The rotation of the grinding disc moves from the center to the edge under the action of centrifugal force. After compaction, degassing and grinding, the material is taken up by the hot air entering from the wind ring at the edge of the grinding disc and dried instantly. The finer particles are brought to the The separator is used for sorting, and the coarse powder is returned to the grinding disc for grinding. The qualified fine powder is taken into a bag dust collector, and the air powder is separated after the finished product is collected. After the finished product is collected, it is transported into the finished product bulk warehouse, and the exhaust gas is discharged after being silenced by the fan. Some difficult-to-grind large-grain materials (and iron knobs and iron slag) enter the external circulation system through the slag outlet at the wind ring. After removing iron, they are fed into the mill by the hoist and ground again. The hot air required for mill drying and ventilation is provided by a hot blast stove, and the shortfall is supplemented from the atmosphere by a cold air valve. The system has large air volume and strong drying capacity, and the moisture of the material into the mill can reach 8-15%
The normal start of the Raymond mill is the beginning to ensure the smooth progress of the milling operation. In actual production, some users often respond to the slow startup of the equipment, and the power of the motor cannot be reached during startup, and it needs to be turned on and off several times to start the equipment normally. This will cause great damage to the equipment. Then, the experts of Shanghai SBM Heavy Industry will analyze the reasons for the slow start of Raymond mill. First of all, when the power of the motor is not enough, during the start-up operation of the equipment, the motor will not be able to operate the Raymond Mill, thereby extending the startup time of the equipment and causing the phenomenon that it cannot be started. Secondly, the Raymond mill has a slow start-up speed, which is caused by too much current during startup. Unstable currents will also cause contactors, motors and circuits to burn out, which will have a great impact on the equipment. If used for a long time, the life of Raymond Mill will be shortened. Again, according to the above situation, when starting the Raymond mill, users need to pay attention to the correct startup sequence and method. For example, before starting the Raymond mill, it is necessary to check the tightness of all inspection doors and observe whether there are any residual substances in the machine. At the same time, adjust the steering of the fan and the host. Then, check whether the exhaust valve of the Raymond mill is fully open, and the tightening condition of each bolt and screw is good. Under all normal conditions, turn on the equipment in the order of starting the hoist, crusher, analyzer, host, feeder, etc. Failure to follow the correct startup sequence can cause equipment damage. Finally, before starting the Raymond mill, ensure the stability of the voltage, so as not to start the Raymond mill when the voltage is unstable, resulting in equipment burnout. Also, during the operation of the equipment, it is strictly forbidden to perform any adjustment, cleaning and maintenance work, and it is strictly forbidden to visit from the upper part of the mill into the machine during operation. The above content about Raymond Mill is briefly introduced here for everyone. I hope it will be helpful to users and friends. If you have any questions, you can consult online.
Cement production mainly relies on slag vertical roller mill to process slag and produce stone powder with different fineness for the production of different specifications of cement. Because the slag powder requires less water than cement, the addition of slag powder can reduce the water-binder ratio of concrete, reduce the amount of concrete bleeding, increase fluidity, improve workability, and pumpability, so maintain good workability and incorporate slag. After powdering, on the one hand, the amount of cement is reduced, and the internal factors of corrosion are reduced; on the other hand, slag powder can be evenly dispersed in the cement slurry because the particles are finer than cement, and these particles are filled in the cement after hydration. In the stone voids, the concrete pore structure is improved, the permeability of the concrete is gradually reduced, the alkali aggregate reaction is effectively suppressed, the sulfate resistance is improved, and the seawater corrosion resistance is enhanced. In general, the ability to resist chemical corrosion is improved and the durability of concrete is enhanced. Therefore, the slag powder can be substituted into the concrete in the same amount to improve the workability of the fresh concrete. According to the different requirements of the concrete, the slag powder can replace 30-70% of the cement in the same amount, and the production cost per cubic concrete can be reduced 15 -30 yuan, other external additives can not achieve this benefit. The slag after the slag vertical grinding process can be used in the production of cement concrete. With the continuous increase of mining in China, more and more mineral resources are being continuously excavated by us, although these mineral resources have greatly improved our lives. However, the accompanying solid waste such as slag and tailings is also increasing. In many cases, these wastes will be accumulated in the suburbs without timely treatment, which not only takes up a lot of land resources, but also causes waste of mineral resources. Therefore, the rational use of slag can promote the healthy development of society. After research by scientific personnel, slag has been widely used in the construction field after processing. Especially in the field of cement manufacturing, slag has become an important production aggregate. Because slag plays an important role in the production of cement, the value of slag has also increased several times, and it has changed from a garbage that was useless to a treasure of value. The slag vertical mill plays an important role in the process of slag transformation. It is also an indispensable and important equipment in cement processing plants. The slag vertical mill itself constitutes a complete set of stone powder production line and has many technical advantages in slag processing. The slag vertical mill is famous for its large output, high fineness, safety, reliability, energy conservation and environmental protection. In modern stone powder processing enterprises, slag vertical mills are widely used. The performance of slag vertical mills has been unanimously affirmed by many users. Stone powder processing plant is the ideal equipment.

The slag vertical roller mill is a kind of negative pressure air-sweeping type grinding equipment. The slag is dried to grind the slag. The slag material enters the center of the grinding disc from the feed port. A small amount of high-moisture new slag and most of the ground non-finished slag with lower moisture are guided under the grinding roller under the action of centrifugal force. By reducing air blowing, the grinding roller compacts the slag exhaust and then grinds The force of the configured material layer is generated by the own weight of the grinding roller and the pressure of the hydraulic system. The grinding roller rotates by friction with the abrasive bed. The sensor and buffer limit device installed on the rocker arm can prevent the grinding roller from directly contacting the metal disc. During normal operation, the distance between the grinding roller and the disc is at least 5mm. Existing problems of slag vertical roller mill: Compared with the raw materials of traditional cement plants, slag has poor abrasiveness and poor abrasiveness. Therefore, the wear of slag vertical roller mills has hindered the development of slag vertical roller mills. With the progress of wear-resistant technology and the introduction of foreign wear-resistant materials, the problem of wear-resistant materials in slag vertical roller mills has been resolved. At present, the general roller sleeves of slag vertical roller mills are the wear-resistant layers of the outer ring of the base material of the casting. Although the problem of wear-resistant materials has been solved, there has been dispute over the thickness of the wear-resistant layer. The thickness of the wear-resistant layer is poor, and the economy is poor. The wear-resistant layer is thin and the service life is low. Therefore, reasonable design of the area and thickness of the surfacing layer becomes the key issue for surfacing. The slag vertical roller mill produced by SBM heavy machine has made unremitting efforts for the successful operation of several equipments from the trial production to the present, and has been making progress in the tests, and such parameters have been reasonably determined in the tests.
Jaw crusher equipment production core internal construction, Shanghai SBM heavy jaw crusher equipment rotating body is mainly composed of moving jaw, eccentric shaft, bearing, pulley and so on several parts, is the main part of the transmission and torque under moving jaw consists of moving jaw toggle plate stents and activities such as parts, jaw support by using 35 # steel casting, and after tempering treatment. The bearing adopts double row centripetal spherical roller bearing, and has the characteristics of fine adjustment, large force and durability. The eccentric shaft is made of no. 45 steel car and is tempered. Jaw plate is divided into two types: movable and fixed. In order to improve the crushing effect, the surface adopts optimized tooth shape and the material adopts ZGMN13, which has the characteristics of high hardness, wear resistance and good use effect. The main component of the fixed body is jaw crusher equipment, the machine manufacturing process has two kinds: medium carbon steel casting frame and medium carbon steel steel plate welding frame. The welding frame is based on the original casting frame and added a number of strong reinforcement, and through strict quality control and specific process requirements, to achieve the same use effect as the casting frame. In order to prevent serious wear on the side wall of the frame, protective plates are installed on the left and right side walls of the crusher chamber, which can be replaced at will. Safety device elbow plate in addition to the transmission force mainly plays a safety role, that is, when the non-crushing into the crushing chamber, elbow plate can be broken or bent first, so as to protect other parts of the machine. The adjusting device is used to adjust the size of the discharge port and control the particle size of the discharge. There are two types of adjusting mechanism of crushing equipment: lifting block type and ejector block type.

Shanghai sbm shibang machinery gypsum powder milling machine processing technology, the crusher crushes the large-scale gypsum ore into small particles smaller than 30mm, and then transports it to the mill for grinding. The raw gypsum powder is sent into the boiling furnace for calcination, and the unqualified materials are returned to the mill for grinding again until it is qualified. The calcined qualified gypsum powder is sent to the clinker bin for storage or used in the product workshop. After the gypsum ore is broken into small particles smaller than 30mm by the crusher, it is sent to the storage bin by the bucket elevator, and the material is evenly and continuously sent to the host for grinding by the electromagnetic vibration feeder. The ground powder is blown by the blower. Under the action, it is blown to the classifier for sorting, and the fine powder after sorting is sent to the storage bin through the pipeline, and finally output through the discharge valve is the finished product. In the grinding chamber of the gypsum mill, the roller assembly is suspended on the roller hanger through the cross arm. The roller hanger is fixedly connected to the main shaft and the blade holder. The pressure spring is tightly pressed against the roller bearing by the tension rod. On the outer end of the cantilever of the chamber, the crossarm axis is used as the support point, and the grinding roller is pressed tightly against the inner surface of the grinding ring by the spring pressure. When the motor rotates through the transmission device, the blade and the blade mounted on the blade holder are The grinding roller rotates synchronously. The grinding roller rotates around itself while rolling on the inner circular surface of the grinding ring. The analyzer drives the analyzer impeller to rotate through the motor transmission device. The rotation speed of the analyzer determines the fineness of the powder.
The mobile construction waste crusher is not concentrated on the accumulation of construction waste or is divided into several areas for processing. Because of the convenience of equipment movement, it can realize the rapid transfer of construction equipment and reduce the capital site investment of large-scale fixed construction waste treatment equipment. , To avoid a large number of construction waste loading, transfer, dumping transportation costs caused by transfer, saving comprehensive cost considerations. At the same time, zero-value construction waste is recycled and crushed into basic materials in short supply on the market. The economic value and social benefits of mobile crushing stations are obvious. In summary, construction muck is just a treasure that is misplaced. Reasonable development and utilization will definitely bring us a lot of benefits. Qingzhou Fukang Machinery has continuously produced new mobile crushing equipment that specializes in solid waste such as construction waste, decoration waste, and engineering waste. Various models are available for your choice.
Jaw crusher is a very widely used crushing machines on the market, and its role in production is very huge. Mechanical failure is inevitable in production and will have a great impact on production. Today we will introduce the reasons for the sudden stop of the jaw crusher. 1) The eccentric shaft tight bushing is loose, resulting in no gap between the two sides of the bearing seat of the frame, making the eccentric shaft stuck and unable to rotate. 2) The discharge port of the jaw crusher is blocked, which causes blockage in the cavity. Remove the blockage from the discharge port of the crusher to ensure unblocked discharge. 3) The voltage at the work site is too low, and the host is unable to break after encountering large materials. 4) The triangular belt driven by the jaw crusher to drive the pulley to rotate is too loose, causing the belt to slip, which causes the stone crusher to stop suddenly when it is working. The above is the reason for the sudden stop of the jaw crusher. These impacts on production have caused great obstacles, and we need to pay attention.
