Complete Gypsum Processing Equipment

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.

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.

SBM is world leading manufacturer and supplier of complete gypsum processing equipment. We provide comprehensive range of gypsum production plant including quarry machine, mining equipment, crushing plant, grinding mill, drying machine, beneficiation equipment etc.

Gypsum Crushing Plant

Crushing the gypsum rock is important stage before processing further, especially if subsequent heating is to be done in a pan rather than a shaft kiln. Crushing will ensure a product which is more uniform and requires less energy to heat. Crushing can be done manually with a hammer or handheld roller, but mechanical crushing is faster and less laborious.

The gypsum crushers include jaw crusher, impact crusher, HCS series cone crusher, track mounted mobile crusher, rubber tyred mobile crusher. These crushing plants are designed in robust structure, with hydraulic control system and overload protection system, feature excellent reliable performance, low energy consumption, cost-effective and high efficiency, create huge profits for gypsum production and make great contribution for mining industry.
