Construction Gypsum Powder Making Machine Plaster of Paris Production Line

Product Description

Product Description
The gypsum powder production line of which the material is natural gypsum, are equipped with many advanced technological equipment.It has been sold to Thailand, Uzbekistan, Columbia and Mexico along with our production line.
The crusher breaks the big sized gypsum ore into small ones with 25mm in diameter. After storingand conveying, they are taken into the mill for grinding. Then, the power concentrator carries thegypsum powders which match to the needed fneness to calciner for calcining. Others are back tothe mill until it is qualifed. In the end, after calcining, the qualifed gypsum powder are sent toclinker container for storing, or are sent to the manufacturing workshops for use.

Crushing section


The gypsum rocks with grain size less than 350mm are sent to the receiving hopper via wheel loader, and then fed into the hammer crusher through feeder. The grain size of the gypsum after primary crushing is 25mm. The broken gypsum is conveyed to the 50 m3 hopper via bucket elevator.
One bag filter is installed in this section to avoid flying of gypsum dust in the course of production, so as to ensure clean and healthy production environment.
The mill section

The grinding section adopts vertical mill grinding. The vertical mill is energy efficient, versatile new grinding equipment. It has the following advantages: High efficiency, low power consumption, large drying capacity, easy to adjust product fineness, particle size uniformly, easy to control chemical composition, low noise, small metal wear, less dust, simple process system, small area covering, saving investment …etc.

Calcining section
Crushed gypsum stones are fed into the calciner evenly through screw conveyor. The gypsum directly connects with hot air and the hot air transfer the heat to the gypsum. The gypsum absorbs the heat and block of part of crystal water then become calcined gypsum (POP). The construction gypsum through screw conveyor and bucket elevator is sent into separator. The exhausted gas out of rotary kiln contains large amount of gypsum powder, after bag dust collector purification, the gypsum powder get into silo and the exhausted gas into the air.
Finish production

The calcined gypsum powder will be conveyed to the storage silo by the elevator.
