Ultra-fine pulverizer improves the physical effect of the pulverizer

Ultra-fine pulverizer improves the physical effect of the pulverizer

The ultra-fine pulverizer is made of stainless steel material, and the material enters the pulverization chamber from the feeding hopper. The pulverization is obtained by the relative motion impact between the vertical fixed knives and the vertical movable knives. The material automatically flows to the exit by the action of the rotating centrifugal force. The particle size of the ultrafine pulverizer is obtained by replacing the screen. The chemical pulverizer reduces the particle size of the material to a certain size, such as grinding flour, pulverizer pulverized feed, pulverizer grinding fine pigment, pulverizer dye and pulverizer cement raw, clinker, pulverizer suspension slurry, super Fine pulverizer and increase the fluidity, filling and easy packing, storage and transportation of materials; chemical pulverizer pulverizes the material into small pieces, fine granules or powders of different grain sizes, such as concrete and road construction Preparation of stone, gravel and artificial sand, ultra-fine pulverizer will be crushed into middle blocks, small pieces and pulverized coal, etc.; chemical pulverizer can increase the surface area of materials, ultra-fine pulverizer to improve the physical role of chemical pulverizer Effect or rate of chemical reaction

First, the workflow of the ultra-fine pulverizer

The complete system of ultrafine pulverizer consists of silo, mechanical pulverizer, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank, etc. The cryogenic pulverizer system uses liquid nitrogen as a cold source, and the pulverized material passes through cooling at low temperature. After achieving the embrittlement and easy pulverization state, the ultrafine pulverizer enters the mechanical pulverizer cavity and rotates at high speed through the impeller. The material and the blade, the toothed disc, the material and the material are repeatedly impacted, collided, sheared, and rubbed under the combined action. , to achieve the crushing effect. The pulverized material is classified and collected by an air flow sieve classifier. The material that has not reached the fineness requirement returns to the silo and continues to be crushed, and most of the cold air is returned to the silo for recycling.

Second, what problems will occur in the operation of the ultra-fine pulverizer

However, there will be problems with the machine. What problems will the ultrafine pulverizer have during the operation? Common problems include hard objects such as stones and iron blocks entering the machine. The anti-injection valve of the ultra-fine pulverizer feed port is improperly adjusted, the conveying pipe is blocked, the mesh hole is blocked, the powder collecting bag is too short or the gas permeability is poor, and the hammer is broken. The city with the edge surface is severely worn and formed into a feed port. Overheating of the bearing When the bearing is poorly smooth, damaged or the spindle is tortuous, the rotor is severely unbalanced, and the belt is too tight, the bearing will overheat. The ultra-fine pulverizer destroys the machine violently. The parts inside the machine are damaged and dropped. If a strange sound occurs, stop it immediately, replace the damaged part or remove the hard object. The ultra-fine pulverizer produces low power, lack of motor power, improper pulley manufacturing, belt slippage, severe wear of the hammer, uneven feeding or high water content of the material is the main reason for the low production power.
