Gypsum a mineral material very important in industry and often used in construction. Gypsum is a hydrate chemically composed of calcium sulfate (CaSO4) and is a widely used industrial and construction material. Gypsum powder is an environmentally friendly mineral powder, which is made by grinding gypsum with a mill.
The crushing gypsum powder production line adopts the domestic mature and advanced process equipment, next to give you an introduction to the production process of gypsum powder.
First, crushing
Gypsum grinding process is generally required to first large pieces of gypsum using a feeder to transfer to the crusher, large size gypsum ore crushed into small pieces of less than 30mm particles of gypsum.
Grinding
The crushed gypsum particles will be sent to the silo through the elevator, and then fed into the grinding chamber of Raymond mill or high-pressure suspension mill for grinding through the vibrating feeder.
Gypsum Grinding Machine
Calcination
The grinding separator will send the gypsum powder which reaches the required fineness to the boiling furnace for calcination, and the part whose particle size does not meet the requirement will be returned to the mill for grinding again until it is qualified.
Finished product
The qualified gypsum powder after calcination is sent to the clinker warehouse for storage or to the product workshop for use.
The processed gypsum powder can be used as the main raw material of concrete expansion agent, anti-cracking agent and self-leveling mortar, and as compound mineralizing agent in the production of special cement. In the concrete industry, gypsum powder is used as a retarder for silicate cement, which is an indispensable additive in the concrete industry.
Gypsum powder can also be used in the production of gypsum building materials, such as plaster, plaster, gypsum mortar, gypsum powder, gypsum board, gypsum partition board, fiber gypsum board, building bricks and so on. In addition, according to the different uses of gypsum powder and different fineness of discharged material, the choice of gypsum mill will be different.
