High pressure grinder
High-pressure mill is suitable for grinding non-flammable and explosive materials such as barite, limestone, ceramics and slag. Mohs hardness is not more than 9.3, and humidity is lower than. The equipment is suitable for high-fine grinding of various materials in mining, metallurgy, chemical industry, building materials and other industries, and the particle size of finished products can be adjusted within the mesh range (up to 800 meshes at the minimum). This machine can produce 30-80 mesh coarse powder by adding special equipment.
Working principle of high pressure mill:
In the high-pressure main engine, a high-pressure spring with the pressure of 1000- 1500 kg is fastened to the drum hanger. After starting to work, the grinding roller rotates around the spindle and clings to the grinding ring under the dual action of high-pressure spring and centrifugal force. Its rotating pressure is 1.2 times higher than that of raymond mill under the same power condition, so the output is greatly improved. When the ground material enters the grinding cavity, it is scooped up by the shovel and sent between the grinding roller and the grinding ring for grinding. The ground powder is brought into the analyzer with the circulating wind of the blower, and the qualified fine powder enters the cyclone powder collector with the airflow to be collected as the finished product, and the large particles fall back for grinding again. The circulating air returns to the blower to repeat the above process, and the remaining air enters the bag filter for purification. When the grinding roller and the grinding ring are worn to a certain extent, adjust the length of the high-pressure spring to keep a constant grinding pressure between the grinding roller and the grinding ring. So as to ensure stable yield and fineness.
Six characteristics of high-pressure mill: compared with other mills, the output is increased by 10-20% under the same power condition, and the grinding force of the roller on materials is increased by 800- 1200 kg under the action of high-pressure spring. All mineral materials can be processed and crushed. The particle size range of finished products is very wide, the coarsest can reach millimeter level (30 mesh), generally 0.033 mm (425 mesh), and the smallest particle size of a few materials can reach 0.0 13 mm (1000 mesh). The dust removal effect fully meets the national dust emission standards. This analyzer is easy to adjust. The grinding device adopts overlapping multi-stage seal, which has good sealing performance. Ultrafine pulverizer
Ultra-fine mill use
SCM series ultra-fine pulverizer is a kind of fine powder and ultra-fine powder processing equipment, which is mainly suitable for middle and low grade India and Mohs India.
Working principle:
The main motor drives the spindle and the turntables at all levels to rotate through the reducer, and the turntables drive dozens of ring rollers to roll and rotate in the ring raceway through the pin shaft.
Large pieces of material are broken into small particles by hammer crusher, and then sent to storage bin by hoist. The electromagnetic vibration feeder sends the materials evenly to the middle of the upper turntable. Under the action of centrifugal force, the materials are scattered to the periphery of the circumference, fall into the raceway of the magic ring, and are stamped, crushed and ground by the ring roller. After the first layer is crushed, the materials fall into the second and third layers. The suction effect of the high-pressure centrifugal fan will bring the outside air into the daughter-in-law machine and the third layer of crushed coarse powder into the powder separator.
The rotating turbine in the classifier makes the coarse materials fall back and regrind, and the fine powder enters the cyclone powder collector with the airflow and is discharged from the discharge valve at the lower part, which is the finished product, while the airflow containing a small amount of fine dust is discharged through the fan and muffler after the essence of the Jinguo pulse dust collector.

JY cone crusher
Use of JY cone crusher:
JY series cone crusher adopts foreign selection technology and technology, with novel and reasonable structural design and high crushing efficiency. It can be widely used in metallurgical industry, building materials industry, road construction industry, chemical industry and silicate industry. JY series cone crusher has three cavity types: coarse crushing type (C), medium crushing type (M) and fine crushing type (SF). Users can choose different cavity types according to their needs to achieve ideal crushing effect.
Working principle of JY cone crusher;
When the cone crusher works, the rotation of the motor passes through the pulley or coupling, the transmission shaft and the cone part of the cone crusher, and rotates around the fixed point under the action of the eccentric sleeve. Therefore, the crushing wall of the crushing cone is close to and far from the surface of the roller mortar wall fixed on the adjusting sleeve, and the ore is constantly impacted, squeezed and bent in the crushing cavity, thus realizing the crushing of the ore. The motor drives the eccentric sleeve to rotate through the bevel gear, which makes the crushing cone do rotary swinging motion. The crushing cone sometimes approaches and sometimes leaves the fixed cone to complete crushing and discharging. The joint between the support sleeve and the frame body is pressed by the spring. When indestructible objects such as metal blocks fall into the crusher, the spring will be compressed and deformed, and foreign objects will be discharged to realize safety and prevent the machine from being damaged.
Characteristics of JY cone crusher: This machine uses layered selective crushing materials. The crushing cavity is full of materials, which are crushed and self-crushed after being squeezed, sheared and kneaded in all directions in the crushing cavity, so that the walls of the crushing cavity avoid direct contact, effectively prevent mutual wear between lining plates and prevent the materials from being polluted by metal pollutants, thus reducing the degree of wearing parts of the machine, effectively prolonging the service life of wear-resistant parts, and the crushing ratio is generally higher than other similar equipment. The crushing ratio of the machine increases, the product granularity is very random, and the size can be adjusted at will. The crushing force of cone crusher is related to the eccentric static torque and rotating speed of the machine. The required crushing ratio can be easily adjusted by adjusting the gap of the crushing cavity. The technical performance of the machine is stable, and the particle size of the product has almost nothing to do with the wear of the liner. Convenient operation and installation. Because the whole machine adopts secondary vibration isolation, the foundation vibration is small and the working noise is small, and there is no need for huge foundation and anchor bolts during installation. Good over-iron performance. Because there is no rigid connection between the moving cone and the transmission mechanism, if the material is mixed with indestructible objects, the moving cone will temporarily stop moving and the vibration exciter will continue to rotate around the axis of the moving cone, which greatly reduces the failure rate. The unique design of the machine simplifies the grinding process and reduces the number of auxiliary equipment. The machine is full of feed and can be started and stopped at full load without special feeder. The operation, monitoring and control are very convenient; Because the product granularity is fine, there is no need for vibrating screen to form a closed circuit, which greatly saves equipment and capital investment. Vertical shaft impact crusher
Vertical shaft impact crusher uses:
PCL vertical shaft impact crusher is widely used in the field of medium and fine crushing of high hardness and superhard materials such as ore, cement, refractory, bauxite clinker, emery and glass raw materials. It is widely used for crushing sand, stone and various metallurgical residues in machine-made buildings. Compared with other types of crushers, it has high output and high efficiency.
Working principle of vertical shaft impact crusher;
The material enters the crusher from the feed hopper and is divided into two parts by the distributor. Part of it enters the high-speed rotating impeller from the middle of the distributor, accelerates rapidly in the impeller, and its acceleration can reach hundreds of times that of gravity, and then it is thrown out of the three evenly distributed flow channels of the impeller at a speed of 60 seconds. First, it collides with a part of materials gathered around the distributor, and then collides with the material lining in the vortex cavity, bounces off by the material lining, and collides obliquely upward on the vortex cavity. This material is subjected to two or more times of probability impact, friction and grinding crushing in the vortex crushing chamber. The crushed material is discharged from the lower discharge port. After three cycles, it can be crushed to less than 20 meshes. In the whole crushing process, the materials themselves impact and crush each other, instead of directly contacting with metal elements, they impact and rub with the material lining, which reduces the angular pollution and prolongs the mechanical wear time. The ingenious air flow self-circulation in the vortex cavity eliminates dust pollution.
The characteristics of vertical shaft impact crusher are simple and reasonable structure and low operating cost. Stone-to-stone and stone-to-iron are efficient, energy-saving and high in crushing efficiency. It has fine grinding and coarse grinding functions. Strong ability to pass through non-broken materials, little influence by material moisture, and water content can reach 8%. It can crush medium-hard and superhard materials (such as corundum, sintered bauxite, etc. ). The product is cubic. Easy to operate, maintain and install. Low working noise and less dust pollution. Easy to operate, maintain and install. New efficient sand making machine
New high-efficiency sand making machine uses:
It can be widely used in the field of medium and fine crushing of high hardness and superhard materials such as various ores, cement, refractories, bauxite clinker, quartz sand, brown corundum, iron ore, basalt, emery and glass raw materials. It is widely used for crushing sand, stone and various metallurgical residues in machine-made buildings, especially for medium-hard and superhard materials. It is superior to other types of crushers and has higher output efficiency.
Principle of a new high-efficiency sand making machine;
Central feeding: the material falls into the waterfall feeding device, enters the high-speed rotating rotor through the central feeding port of the sand making machine, is fully accelerated, and is thrown out through the discharge port. First, it collides with a part of the material that falls freely after rebounding, then collides with the vortex lining in the surrounding vortex cavity, then bounces to the top of the crushing cavity, deflects downward and collides with the material discharged by the impeller wheel to form a continuous curtain, and finally is discharged through the lower discharge port.
The central feeding of the new sand making machine is accompanied by the annular waterfall feeding: the material falls into the waterfall feeding device, then falls through the annular hole and is divided into two parts by the bulk tray. One part enters the impeller rotating at high speed through the central inlet, and the other part falls around the powder tray. The material entering the impeller is rapidly accelerated in the impeller and then thrown out at high speed. First, it collides with another part of the material falling freely around the bulk tray, and then collides with the vortex lining in the surrounding vortex cavity. First, it bounces back to the top of the crushing cavity, then deflects downward, collides with the material discharged by the impeller wheel to form a continuous material curtain, and finally is discharged through the lower discharge port.
Features of the new high-efficiency sand maker: large capacity, high output of -50-500t/h, compared with the sand maker with the same power, the output is increased by 35%. And the performance is relatively stable. Low consumption of wearing parts-the most ideal impact crushing, impact angle, the most reasonable material impact speed design and less friction of wear-resistant parts, which is 30% lower than the running cost of traditional equipment, directly reducing the use cost of impact crusher and greatly improving the profit rate of the machine. The finished product has a good grain shape-hexagonal polyhedron, which is reasonable in collocation, and is especially suitable for the molding of machine-made sand and machine-made stone. Many customers have proved that the comprehensive effect of sand making and molding is 30% higher than that of other equipment with the same power. vibrating screen
Vibrating screen uses:
The vibrating screen is mainly used to screen dry materials such as metallurgy, coal and ore, and its motion trajectory is similar to a circle. This machine adopts domestic advanced ring groove rivet connection and large clearance bearing oil lubricated vibrator, which has the characteristics of durability, stable operation, low noise and convenient installation and maintenance.
Working principle of vibrating screen:
The inclination angle of the screen surface of the vibrating screen is usually below 8, and the vibration angle of the screen surface is generally 45, and the screen surface does linear reciprocating motion under the action of the vibration exciter. Particles are sprayed and dropped under the vibration of the screen surface, which makes the materials move forward continuously during the vibration of the screen surface. The throwing and falling of materials have an impact on the screen surface, so that particles smaller than the screen holes are screened and separated. The screening efficiency and productivity of screen are related to the inclination angle of screen surface, vibration angle of screen surface and material throwing coefficient. In order to ensure high screening efficiency and large screen output, it is necessary to choose appropriate projection coefficient values.
Characteristics of vibrating screen: using block eccentricity as exciting force, it has strong exciting force. The screen beam and screen box adopt high-strength bolts, which have simple structure and convenient maintenance. Using tire coupling, the connection is flexible and the operation is stable. The structure of small amplitude, high frequency and large inclination angle makes the machine have high screening efficiency, maximum handling capacity, long service life, low power consumption and low noise. sand washer
