Natural Gypsum Powder Plant

Gypsum is an important architectural material. We’ve been developing and manufacturing gypsum processing devices since 1998. We offer a complete natural gypsum plant solution according to the location of your factory, plant area and market conditions. Production power of our plant is 20,000/ Year - 500,000 / year. We also offer replacement and upgrade services on devices in your plant. We provide worldwide services whenever you need.

Multiple processes are taken in production of the plant. First, gypsum ores get broken, conveyed and stored into raw material bin. Then the materials get grinded into powder with fineness required. Powder is then conveyed into calcining section via metering feeding device to get calcined. Then the calcined gypsum get modified by grinder and cooled by cooling device. Finally the finished gypsum are conveyed for storage. The plant consists of these sections/units:

• A material supplement stabilizing system is deployed to achieve stable supplement of the fluidized bed combustion boiler, and to stabilize material supplement and heating. Material supplement stabilizing system consists of material supplement stabilizing bin and conveying device (metering screw or belt weigher).
• Calcining system applies hot air boiling furnace calcining process to perform even calcination on gypsum material.
• Cooling device added to cool down calcined gypsum before it enters silo, to prevent gypsum from deterioration caused by over temperature.
• Silo turn-over system: materials at different time periods feature different quality, therefore products made from them feature different quality. The silo turn-over system can evenly mix new and old materials, make the products share the same quality. Besides, the system prevents overheating deterioration caused by heat generated by powder accumulation.
• The dust removal system applies a bag type dust collector, to ensure dust generated during pre-drying, conveying, grinding, calcination and aging processes get cleaned before discharging outside, to meet working environmental requirements.
• Distributed control system is applied, to do centralized control on distributed devices.
