Gypsum powder production line works based on the following process:

The Crusher will break the big-size gypsum ore into small 25mm pieces, and then the small pieces will be sent to the grinder, after grinding fine, the qualified raw gypsum powder will be sent to boiling furnace to calcine, and the unqualified part will be sent to grinder until it's qualified. After calcining, the qualified gypsum powder will be sent to spiral conveyor through hoist.

The spiral conveyor will send the calcined gypsum powder to silo for storage, and cool the powder during the process. The dust remover is on the top of silo, the unqualified part will be sent to grinder until it's qualified.
The stored gypsum will be sent to product storage through steel impeller feeder, spiral conveyor, hoist, and send the qualified gypsum powder to storage or workshop finally.

The top pulse bag-type dust remover will collect dust from crusher, particle silo. When the dust and dust gas get into the dust remover through inlet, the big-size dust particle will fall because the increasing size and decreasing wind speed. The small dust particle will be filtered by filter bag. The filtered gas will be got rid of by outlet.
