Gypsum Grinding Production Line

Before gypsum can be processed and used to make a wide range of products, it first has to be removed from the ground. Gypsum is either mined or quarried at numerous locations. After the extracted, the gypsum ore will be conveyed to gypsum grinding production line. A special conveyor called a pan feeder carries the rock into a crusher. The crusher breaks up those rocks larger than two inches in diameter; smaller rocks are fed directly into the rock dryer.

The rock dryer is a huge rotating kiln or oven which evaporates any surface moisture on the rock. The dry gypsum is now ready to be ground. The rock is ground in a roller type crushing mill called a Raymond mill. These powerful machines grind the gypsum into a fine powder, called “land plaster.”

Gypsum Powder Production Process

Gypsum ore, extracted from quarries and underground mines, is crushed and stockpiled near a plant. As needed, the primary crushed gypsum ore is further crushed and screened to about 50 mm in diameter. If the moisture content of the mined ore is greater than about 0.5 weight percent, the ore must be dried in a rotary dryer or a heated roller mill. Ore dried in a rotary dryer is conveyed to a roller mill, where it is ground to the extent that 90 percent of it is less 100 mesh.

Gypsum Power Grinding Mill

Gypsum grinding mill is no doubt the most important machinery in gypsum powder production plant. Grinding is the energy consuming process. It is crucial to choose proper powder mill with high performance and capacity.
