The diameter of gypsum lump should less than 300mm, we use bucket lift truck or manpower transport gypsum lump into jaw crusher, stone crusher gypsum plaster stone, so that less than50mm, the bucket elevator and screw conveyor into the grinder bin.
Grinding Powder Process
The gypsum materials from crushing process, they will be conveying into mill silo pass through bucket elevator and screw conveyor. These gypsum materials will be evenly feed into mill via vibrating feeder, the small size gypsum materials will become to gypsum powder due to the grinding effect, gypsum powder will go out of mill with wind, and will be chosen by powder separator which is on the top of mill, the qualified fineness of powder are separated from the top of mill, other unqualified powder will return into mill for grind again.
