What is the crushing principle of the mass production airflow powder machine

Mass production airflow powder machine is used for mass and large-scale production, can handle more than 5 kg/h material crushing, widely used in pharmaceutical, chemical, food, cosmetics and other industries
.

The crushing principle of the mass production airflow powder machine: 1, feed The raw material to be crushed is evenly fed through the feeder, and the material is sucked in through the gas injected at the inlet end to produce negative pressure, and the material is sprayed into the grinding chamber
.

2, grinding The supersonic speed generated by the nozzle around the grinding chamber is injected into the crushing chamber along the direction of the set tangent, and the gas-solid two-phase flow forms a high-speed swirl, and the material rotates at a high speed in the cavity along the tangential direction, so that the materials collide with each other, friction, and grind the material
.

When the material rotates at high speed in the crushing chamber, the material particles rub against each other, and the particles collide and rub
against each other.

So that the material particles will be smaller and smaller, the large particles of the material due to the centrifugal force and will continue to do high-speed rotation on the edge of the inner wall of the grinding chamber to rub each other, with the reduction of material particles, centrifugal force will also be reduced, particles will also move to the grinding chamber, when the centrifugal force is less than the force generated by the outlet gas flow, the material will be brought out of the outlet with the air flow
.

3, the collection of the role of centrifugal force will make the larger particles in the periphery of the crushing chamber moving, and the smaller particles with the spiral air flow gradually close to the middle of the crushing chamber, the crushed ultrafine material, the ultrafine particles due to the loss of mass and loss of centrifugal force, out of the swirl field
.

Under the differential pressure force, it enters the cyclone separator through the middle discharge pipe, and most of the material moves downward into the storage container, and the gas is discharged
upwards.
