Firstly, raw materials will be crushed by jaw crusher to the specified sizes, then the crushed materials are elevated into a hopper. By the vibrating feeder, materials are fed into the grinding chamber evenly and continuously for powder-processing, After that, the grinder powder is carried by the air into the separator for screening. The qualified powder is blown into the cyclone collector and poured out through the output-powder valve as the final products. The rough powder will be recycled back into the grinding chamber for re-grinding. The set’s airflow system is closely sealed up and circled under the condition of negative pressure.
