Working principle and structure of roller crusher equipment

1. This series of roller crushers are mainly composed of rollers, roller supporting bearings, pressing and adjusting devices, and driving devices. 2. Adjustment of the discharging granularity: a wedge or gasket adjustment device is installed between the two rollers, and the top of the wedge device is equipped with an adjustment bolt. When the adjustment bolt pulls the wedge up, the wedge pushes away the movable roller. The fixed wheel, that is, the gap between the two rollers becomes larger, and the discharging particle size becomes larger. When the wedge is downward, the movable roller is under the action of the compression spring and the gap between the two wheels becomes smaller, and the discharging particle size becomes smaller. The gasket device adjusts the discharging particle size by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger, and when the gasket is reduced, the gap between the two rollers becomes smaller and the discharge particle size becomes smaller. . 3. The driving mechanism is composed of two motors, which are driven by a V-belt to the pulley to drag the roller, and rotate according to the relative direction. When crushing the material, the material passes through the roller from the feed port, and is crushed by rolling, and the crushed product is discharged from the bottom of the chassis. 4. For safety, the transmission part should be installed with a safety cover according to the actual situation.

What are the irreplaceable functions of the jet mill

Jet mills are widely used in chemical, mineral, metallurgy, abrasives, ceramics, refractory materials, medicine, pesticides, food, health products, new materials and other industries. The reason why people choose it as a factory production equipment is that the jet mill does have an irreplaceable role. The working principle of the jet mill: The qualified fine powder is brought into the turbo classifier above the fluidized bed by the updraft, and the qualified materials are classified by the jet mill and enter the cyclone collector (if you need products with several particle sizes, you can add several vertical turbo classifiers) . The finer tailings are brought into the bag filter by the airflow, and after being filtered by the bag filter, the tailings enter the discharge port at the lower part of the filter, and the pure air is evacuated. The main components of the machine: standard vertical turbine classifier, the crushing and classification are synchronized and coordinated. The speed of the powder concentrator can be adjusted by frequency conversion, and the fineness of the product can be adjusted arbitrarily. For example, if a processing process requires products with multiple particle sizes, you can add two to four more than one classifier as the standard, so that the machine becomes a two-machine five-machine for crushing and classification. Scope of application: The crushing mechanism of this machine determines its wide application range and high fineness of the finished product. Typical materials are superhard diamond, silicon carbide, metal powder and so on. , Ceramic pigments, medicine, biochemistry, etc. High purity, low temperature of medicine and PVC. By changing the ordinary air in the gas source into inert gases such as nitrogen and carbon dioxide, the machine can be used as an inert gas protection device, suitable for the crushing and classification of flammable, explosive, and oxidizing materials. Application of jet mill: 1. High hardness materials: silicon carbide, various corundum, boron carbide, alumina, zirconia, garnet, zircon sand, diamond, etc. 2. Non-metallic minerals: timing, graphite, kaolin, calcium carbonate, mica, barite, mullite, medical stone, wollastonite, talc, pyrophyllite, etc. 3. Chemical industry: aluminum hydroxide, silica gel, various dyes, epoxy resins, various additives, etc. 4. Food and medicine: pollen, hawthorn, pearl powder, Ganoderma lucidum, various vegetable powder, various Chinese herbal medicine, various health products, cosmetics, antibiotics, etc. 5. Metal materials: aluminum powder, magnesium powder, zinc powder, tin powder, copper powder, etc. 6. Other materials: ceramic materials, refractory materials, electronic materials, magnetic materials, rare earth materials, phosphors, copy material powders, etc. Features of jet mill: 1. Large output, low energy consumption and high classification efficiency. 2. Concentrated particle size: This machine uses the original vertical impeller for classification. The stable classification technology and special sealing measures effectively prevent the leakage of coarse particles, so that the product has no large particles, the particle size is concentrated, and the classification accuracy is high. 3. Reasonable structure: products with 1-6 grain sizes can be produced at the same time according to user requirements. 4. Strong applicability: It can be used in combination with various mills (jet mill, mechanical mill, ball mill, Raymond mill, vibration mill, etc.). ) Form a closed-circuit or open-circuit joint operation. 5.

What are the types of jet mills

The main applicable crushing mechanism of the jet mill determines its wide application range and high fineness of the finished product. Typical materials are superhard diamond, silicon carbide, metal powder and so on. , Ceramic pigments, medicine, biochemistry, etc. High purity, low temperature of medicine and PVC. By changing the ordinary air in the gas source into inert gases such as nitrogen and carbon dioxide, the machine can be used as an inert gas protection device, suitable for the crushing and classification of flammable, explosive, and oxidizing materials. The jet mill, cyclone separator, dust collector and induced draft fan form a complete pulverizing system. After the compressed air is filtered and dried, it is sprayed into the crushing cavity at high speed through the Laval nozzle. The materials are repeatedly collided, rubbed, and sheared at the intersection of multiple high-pressure air streams. Under the action of the suction of the fan, the crushed materials move to the classification area with the updraft. Under the action of the strong centrifugal force generated by the high-speed rotating classifying turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements are collected by the cyclone separator and dust collector through the classification wheel, and the coarse particles drop to the crushing zone and continue to be crushed. There are several types of jet mills used in industry: flat jet mills, fluidized bed jet mills, circulating tube jet mills, jet mills and target jet mills. Among these types of jet mills, flat jet mills, fluidized bed jet mills and circulating tube jet mills are widely used. Convection jet pulverizer After the material enters the crushing chamber through the screw feeder, the impact energy of the high-speed airflow is ejected from several oppositely arranged nozzles, and the airflow rapidly expands into the fluidized bed and the collision friction force generated by the suspension and boiling breaks the material. Driven by the negative pressure airflow, the coarse and fine mixed powder passes through the turbine classification device at the top, the fine powder is forced through the classification device, and is captured by the cyclone collector and the bag filter. The coarse powder is combined by the gravity generated by the high-speed rotating classification device. The centrifugal force hits the four walls, and then settles back to the crushing chamber to continue crushing. Flat jet mill The high-pressure air flow as the kinetic energy of the crushing enters the stable air storage bag outside the crushing chamber as the air distribution station. The air flow is accelerated into a supersonic air flow through the Laval nozzle and then enters the crushing mill cavity. The material is accelerated and then introduced into the crushing mill cavity through the Venturi nozzle Perform synchronous crushing. Because the Laval nozzle is installed at an acute angle with the crushing chamber, the high-speed jet will circulate the animal material in the crushing chamber, and the particles will collide with each other and collide with the wall of the fixed target plate to frictionally break. The fine particles are introduced into the central outlet pipe of the pulverizer, and are collected in the cyclone separator driven by the centripetal air flow. The coarse powder is thrown toward the peripheral wall of the pulverizing chamber for circular motion and continues to be crushed. Circulating tubular jet mill The raw materials are fed into the crushing chamber through the venturi nozzle, and the high-pressure airflow is sprayed into the racetrack-shaped circular tube crushing chamber with variable diameters and variable curvatures through a set of nozzles, accelerating the collision, collision, friction and crushing of particles. At the same time, the cyclone also drives the crushed particles along the pipeline into the classification zone. Under the action of the centrifugal force field in the classification zone, the dense material flow is divided, and the fine particles are discharged after being classified by the inner louver inertial classifier. Coarse particles return to the outer layer along the downcomer and continue to circulate and crush. Fluidized bed jet mill The jet mill (fluidized bed jet mill) accelerates the compressed air through the Laval nozzle into a supersonic airflow, and then sprays it into the smashing zone to fluidize the material (the airflow expands into a fluidized bed suspension, boiling, and colliding with each other). Every particle has the same state of motion. In the crushing zone, the accelerated particles collide with each other and are broken at the intersection of the nozzles. The pulverized material is transported to the grading area by the updraft. The fine powder that meets the particle size requirements is sieved by the horizontal grading wheel, and the coarse powder that does n

How does the jet mill control the particle size?

How does the jet mill control the particle size? The smaller the particle size of the raw material, the higher the crushing efficiency. On the contrary, the larger the particle size of the raw material, the lower the crushing effect. When the crushing pressure and the feed pressure are constant, the product will be finer when the feed rate is reduced, and the product will become coarser when the feed rate is increased. In the case of a certain feed rate, the particle size of the product will be finer when the crushing pressure is increased, and the product will become coarser when the crushing pressure is reduced. Therefore, the particle size control is achieved by adjusting the parameters of the jet mill during the crushing process to achieve different crushing fineness. Before crushing, the relationship between the feed rate and the pressure needs to be measured and then the appropriate crushing parameters are determined to meet the customer's particle size requirements. . The particle size of the end product needs to be checked with a particle size detector to check the fineness and distribution range. In addition, if the electron microscope is used for measurement, it can be more accurate. Of course, the detection result can also be compared with the particle size detector. How does the jet mill adjust the particle size of the finished product? Generally, the particle size of the jet mill can be adjusted by the change in the feed rate. When the rate is reduced, finer particles can be produced. Since each particle has more energy to accelerate the impact and crushing, it provides a greater power supply, which becomes the impact of crushing. The important force of, you can also get more fine grain size, it is under the premise of energy consumption. Some products need high-level application of crushing energy to crush. Jet mills can improve crushing characteristics, increase pressure, temperature, gas flow control, etc. Increasing temperature will also change the material, all control particle size, but also need to consider the physics and chemistry of the material characteristic. Adjust the output power of the diameter grinder properly. Some particles must be processed when they have a low resonance, which requires multiple collisions. Therefore, when the resonance is increased, the particle speed is given a lower energy for each collision. On the other hand, to reduce the number of particles, the speed of the particles must be increased. In addition, pay attention to the use of the equipment, read the instructions carefully before operating, and understand the characteristics and structure of the equipment. It is not possible to increase the speed of the spindle, and there should be no lumps in the material, which will cause damage to the equipment. When loading the material, it should be on the side of the material opening to prevent the material from flying out. The bearing temperature must be below 55 degrees, and the equipment must be stopped for inspection if it is too hot. Clean up the materials in the collection bag. When replacing the hammer, open the casing to clean up the blockage and cut off the power supply. At the end of the work, the equipment must be cleaned and protected from fire. People who don't know the equipment or people who are drunk or sick are not allowed to operate it. Do not use inferior hammers, which will affect the service time of the equipment. If there is a fault, please check again after power off. The equipment must have a protective cover when it is working, and the equipment must be checked before starting the machine.
