After the bulk material is crushed to the required particle size by the jaw crusher, the material will be sent to the storage hopper by the elevator.Then, the materials are continuously and uniformly fed into the grinding chamber of the host machine through electromagnetic vibrating feeder for grinding. The material after grinding is sent into the separator by the airflow of the fan for classification. Under the action of the impeller of the separator, the materials that do not meet the fineness requirements fall into the grinding chamber and are re-milled. The pipeline enters the cyclone powder collector for separation and collection, and the finished powder is discharged through the discharge device. The separated airflow enters the fan through the air return pipe at the upper end of the cyclone powder collector.
