Operational Principal
The material enters the crushing room through the material feeder. The compression air nozzles enter the crushing room in high speed through the specially equipped four crushing nozzles. The material gains acceleration in the ultrasonic jetting flow and repeatedly impact and collide at the central converging point of the crushing room until it is crushed. The crushed material enters the grading room with the up flow. Because the grading wheels spin at high speed, when the material ascends, the particles are under the centrifugal force created from the grading rotors as well as the centripetal force created from the viscosity of the airflow. When the particles is under the centrifugal force larger than the centripetal force, the coarse particles with larger diameter than the required grading particles will not enter the inner chamber of the grading wheel and will return to the crushing room to be crushed. The fine particles that comply with the diameter of the required grading particles will enter the grading wheel and flow into the cyclone separator of the inner chamber of the grading wheel with the airflow and get collected by the collector. The filtered air is released from the air in taker after the filter bag treatment.
Advantage
1. NO rise in temperature: the temperature will not increas as the materials are pulverized under the working nditions of pneumatic expansion and the temperatu in the milling cavity is kept normal
2. No contamination: the whole process is nnination-free as the materials are moved by the airflow and ground through the collision and impact among themselves without involving the media
3. Endurance: Applied to materials with mohs' hardness below grade 9,since the milling effect only involves the impact and collision among the grains rather than the collison with the wall
4. Inert gas can be used as media for milling flammable and elosive materials.
