Gypsum grinding Mill is developed from the raymond mill. After being grinded by the gypsum grinding mill,the gypsum

　　powder(usually is about 120-200 mesh) mainly are used in the production of paper faced gypsum board.

　　In order to make the paper faced gypsum board, the raw gypsum powder should be calcined in advance.

　　( 2 CaSO4 *2H2O (calcined) = 2 CaSO4*1/2 H2O + 3H2O ). The calcined gypsum powder is named plaster of paris.

　　Working Principle of Gypsum Grinding Mill :

　　01. Jaw Crusher crush the gypsum rock into smaller size in advance.

　　02. Bucket elevator sends the crushed gypsum rock into hopper.

　　03. Vibrating feeder sends the crushed gypsum rock into the grinding chamber of gypsum mill (Raymond Mill).

　　04. Roller and Ring grind the gypsum rock into powder. Under the function of blower and analyzer machine, only the fine powder can go through the analyzer machine, the coarse powder falls down and to be grinded again.

　　05. The fine powder which meets the requirement finally goes out through the cyclone powder collector as final products.
