Gypsum Board Manufacturing Machine

Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant. As needed, the stockpiled ore is further crushed and screened to about 50 millimeters (2 inches) 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 149 micrometers (μm) (100 mesh). The ground gypsum exits the mill in a gas stream and is collected in a product cyclone.

Ore is sometimes dried in the roller mill by heating the gas stream, so that drying and grinding are accomplished simultaneously and no rotary dryer is needed. The finely ground gypsum ore is known as land plaster, which may be used as a soil conditioner.

At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills.

Gypsum Processing Plant for Cement Production

Gypsum Crushing Plant: As we know, gypsum is an extremely soft mineral at 1 to 2 on Mohs’ hardness scale. Basically, the process of gypsum crushing only needs one crushing step. As for the selection of gypsum crushing plant, Zenith specialists suggest using the portable crushing plant. A portable crushing plant always integrates the crushing, sorting and conveying in a machine. Its integrative installment reduces the installation of the complex infrastructure and accessory equipment, which can lower the consumption of materials and labors to a great degree.

Gypsum Grinding Plant: In the cement industry, crushed gypsum particles should be further grinded by gypsum grinding plant. There are varied types of gypsum grinding plant, including the ball mill, Raymond mill, vertical mill, trapezium mill, coarse powder mill, and ultrafine mill, etc. As for the selection of gypsum grinding plant, Zenith experts suggest using the MTW trapezium mill, which has an internal oil pump which can lubricate the bearings both in main shaft and bevel gear shaft, without connecting any external oil pump or lubrication station.
