Gypsum powder plant introduction:
We use the advanced technology to produce the gypsum power machine from 30,000 tons per year to 300,000 tons per year
Gypsum powder machine
The gypsum stone is crushed into granule less than 25mm with crusher. It is stored in raw material silo, then conveyed into grinding mill to make gypsum powder. The powder is classified through a classifier. The qualified powder in required fineness shall be carried to the calciner, while the unqualified powder shall be returned to the grinding mill for further process. The calcined gypsum powder (it is usually called Plaster of Paris) shall be stored in the finished product silo for preparation of plasterboard raw material.

As the gypsum industry develops, the gypsum powder demand becomes larger and larger in many fields. Meanwhile the requirement for gypsum powder quality becomes stricter. Therefore the gypsum power process improves gradually. Drying and dehydrating the raw gypsum powder are a critical process and the most difficult to control. After many years of research and experiment, we have successfully developed the advanced calcining device-fluidized bed calciner, suitable for all kinds of gypsum powder production. 
plaster equipment adopts the latest technology of fluidized furnace type.
