Airflow milling is large, high automation, fine product particle size, narrow particle size distribution, high purity, high activity, good dispersibility, etc., is widely used.Airflow pulverizer is a high-speed airflow to achieve ultrafine pulverized equipment with dry materials. The full utilization rate of jet is high, and the pulverization is not warmed, no pollution, and the wear small precision is highly significant. It is widely used in low temperature, high purity and high hardness materials to ultrafine pulverization, flammable, explosive, and easy oxidation materials can be used to achieve closed circuit pulverization, inertial bonus cyclic use with inert gas as a medium. The gas flow pulverizer is a special set of crushing systems by several parts of airflow pulverizer, cyclone collector, dust collector, air blower, and electric control cabinet. After the compressed air is dried, the pulverizing cavity is sprayed by the Lavar nozzle, and the material is repeatedly collided with the intersection of the multi-shaped high pressure airflow, and the crushing material is pulverized, and the crushing material will enter the grading cavity. Under the centrifugal force generated by the high-speed graded impeller, the thick particles are separated from the gas stream, and the fine particles required to meet the particle diameter requirements are collected into the cyclone collector and the dust collector through the grading impeller blade gap, and the crude particles are graded. Go out and dropped to the crushing area to continue to smash.
Small airflow pulverizer
my country's currently widely used airflow pulverizer has a flat air current pulverizer, fluidized bed airflow pulverizer, circulating tube gas flow pulverizer. The flat airflow pulverizer enters the regulated gas storage package in the periphery of the pulverized chamber as a gas flow distribution station as a gas flow distribution station, which accelerates the pulverizing gas flow after the Raval nozzle is accelerated, and the material is accelerating the nozzle in the material. The introduction of the pulverized grinding chamber for synchronous pulverization. Since the Lavar nozzle is mounted in an acute angle and the pulverizing cavity is installed, the high-speed jet flows in the pulverizing cavity, and the particles and the particles are generated by mutual impact, collision, and rubbing between the particles and the fixed target sheet. The fine particles are introduced into the heart gas flow to enter the cyclone to enter the cyclone separator, and the coarse powder is pulled to the pulverizing the wall under the action of the centrifugal force and continues to be pulverized. The fluidized bed gas flow pulverizer is that the compressed air is accelerated by the Lavar nozzle to accelerate the ultrasonic speed flow, and the material is fluidized (the airflow expansion is suspended from each other), so each particle is collided with each other. Has the same motion state. In the crush area, accelerated particles in each nozzleThe discharge points are hit by each other. The crushing material is delivered to the hierarchical region, and the fine powder reaching the particle size required by horizontally arranged ranking wheels, and the coarse powder that does not reach the particle size requirement continues to be pulverized. Qualified fine powder enters the high-efficiency cyclonic separator with the airflow to obtain the collected gas, and the dust is discharged into the atmosphere after filtering the dust filter. Fluidized bed airflow pulverizer circulating tube gas flow pulverizer The raw material is added to the Wenqiao nozzle, and the high-pressure gas stream is sprayed into a runway circulating tube-type pulverizing cavity of a set of nozzles, and accelerates the mutual impact of the granules. Collision, rubbing and pulverizing. At the same time, the swirl also drives the pulverized particles to enter the hierarchical region along the conduit, and the intensive stream is discharged under the action of the fractional zone centrifugal force field, and the fine particles are discharged after the inner layer is graded. The crude particles returned to continue cyclic pulverity along the underlying line. The inert gas protection airflow pulverizing gas flow pulverizer is widely used in chemical, minerals, metallurgy, abrasives, ceramics, refractory materials, pharmaceuticals, pesticides, food, health products, new materials and other industries. This is inseparable from its significant performance advantage, and the performance characteristics of the airflow pulverizer are: 1. Variable combination structure: one machine, both smash, and separate grading; 2. Multi-level series: can be configured 1-5 classification machine, production granularity requires a narrow product; 3. Small granularity range: The finished product particle size is adjustable between D97 = 3-150 microns, granular shape; 4. The whole system is closed, dust is less Low noise, clean environmental protection; 5. The control system uses program control and easy operation.
