[0002] Airflow pulverizer is a widely applicable pulverizing machine, widely used in biomedicine, metal powder preparation and other industries. The principle of airflow pulverizer is: after the material enters the pulverizing chamber through the feeding system, the high-speed airflow impact in the pulverizing chamber produces repeated collision, friction and shearing with the inner wall of the pulverizing chamber, thereby becoming particles with smaller particle size. The pulverized material moves with the rising airflow under the action of wind force. During the movement, the materials of different particle sizes are separated through the grading chamber, the fine particles are collected, and the coarse particles fall into the pulverizing chamber for further pulverization. Therefore, the mixing mechanism of the airflow pulverizer plays an important role.
