A common pulverizer such as an air flow pulverizer is composed of an air blower and a pulverizing cavity, the air blower sprays high-pressure air flow into the pulverizing cavity, material particles move circularly along with the high-pressure air flow, so that the material particles are impacted, collided and rubbed with each other to be pulverized, wherein the material particles are subjected to the action of centrifugal force (F is 2mr omega, m is the mass of the particles, r is the rotating radius, omega is the rotating speed) generated by rotation, the material particles with larger particle size continue to rotate because the centrifugal force acting on the material particles is larger due to the larger mass, the particles with smaller particle size continue to rotate because the centrifugal force acting on the material particles is smaller due to the smaller mass, so the particles can be discharged outwards along with the flow direction of the high-pressure air flow, but the material particles are easy to move along with the high-pressure air flow and can be discharged along with the discharge of the high-pressure air flow, so that the collection rate of the material particles is low, and the material particles are too many, and the bottom sinking phenomenon is easy to occur, the high-pressure airflow can only roll up a thin layer of material particles to continue crushing, so that the crushing efficiency is slowed down, meanwhile, the material particles are too large and have large mass, and the force provided by the high-pressure airflow is not enough to enable the material particles to do circular motion, so that the crushing effect is deteriorated.
Meanwhile, in the crushing process, because crushing and scattering are avoided, all the crushers are closed, and therefore material particles are easy to stick to the cavity, so that the problems of material pollution and low yield are caused.
