The Super Pressure Trapezium Mill consists of a main machine, a high density powder separator, connecting pipes, a centrifugal induced draft fan, a square box bag dust collector, a crusher, a dustpan elevator, a storage hopper, an electromagnetic vibrating feeder and an electric control cabinet.
After the jaw crusher crushes the bulk material to the required size, the material is sent to the storage hopper by the elevator, and then the electromagnetic vibrating feeder feeds the material into the grinding chamber of the main machine in an even and continuous manner. Under the action of the impeller of the powder selector, the materials that do not meet the fineness requirements fall into the grinding chamber for regrinding, while the materials that meet the fineness requirements enter the cyclone powder collector with the airflow for separation and collection, and are discharged through the discharge device as finished powder. The separated airflow enters the fan through the return duct at the upper end of the cyclone collector. The system is a closed circuit system and operates under positive and negative pressure.
