Gypsum powder is one of the five major gel materials and plays an important role in the national economy. The gypsum powder production line is to heat natural dihydrate gypsum ore (raw gypsum) or industrial by-product gypsum (desulfurization gypsum, phosphogypsum, etc.) after heating at a certain temperature. And grinding, so that the dihydrate gypsum is decomposed and decomposed, and the obtained product containing β hemihydrate gypsum as the main component is the building gypsum (passing for the plaster).

The process flow of the gypsum milling production line:
The crusher breaks the large-sized gypsum ore into small pieces of less than 30mm, and sends them to the mill for grinding. After the gypsum grinding equipment, the gypsum raw powder which has reached the required fineness of the product after grinding is sent to the boiling furnace for calcination. Partially returned to the mill for re-grinding until qualified. The qualified gypsum powder after calcination is sent to the clinker silo for storage or sent to the product workshop for use.

According to the process requirements, the construction gypsum production line is usually divided into five parts, namely the crushing system, the grinding system, the calcining system, the storage conveying system and the electronic control system.

(1) Crushing system: The gypsum raw material enters the crusher through the feeder, and the crusher breaks the large-sized gypsum ore into small pieces of less than 30 mm for use. According to the size of gypsum raw materials and different production requirements, you can choose the crusher of the corresponding specifications, usually choose jaw crusher, hammer crusher or impact crusher. In order to protect the environment, it can be equipped with dust removal equipment to meet environmental emission requirements.

(2) Raw material transportation: The crushed gypsum raw material is transported to the storage bin through the hoist to be used. The storage bin is designed according to the requirements of material storage time to ensure a stable supply of materials.

(3) Grinding system: The material is uniformly and continuously fed into the stone grinding equipment through the electromagnetic vibrating feeder for grinding. The ground gypsum powder is blown out by the air blown by the mill blower and classified by an analyzer above the main machine. The powder with fineness conforms to the specification, enters the large cyclone collector with the wind flow, and is discharged after being discharged through the powder discharge tube. The finished product falls into the screw conveyor and is transported to the next system for calcination. The entire air duct system is closed and closed. A bag filter is introduced from the pipe between the large cyclone collector and the blower to remove dust from the air and then discharged into the environment to ensure a clean environment. The material of the grinding system is changed from the particle size of 0-30mm to 80-120 mesh, which meets the requirements of gypsum powder fineness.

(4) Calcination system: The system mainly includes equipment such as hoist, boiling furnace, electrostatic precipitator and Roots blower.

(5) Electrical control system.
