.
Gypsum powder is usually white, colorless, and the colorless transparent crystal is called transparent gypsum. Sometimes it is gray, light yellow and light brown due to impurities. The streak is white. Transparent. Glass luster, cleavage surface pearl luster, fibrous aggregate silky luster.
The cleavage is extremely complete, and medium, and the cleavage sheet is split into a rhomboid with an angle of 66 and 114. Crisp. Hardness 1.5~2. The direction is slightly different. The relative density is 2.3.

(1) Gypsum crushing;
The crusher breaks the large-sized gypsum ore into small pieces of less than 30mm and transports it to the mill for grinding;
(2) Gypsum grinding;
The powder sorting machine feeds the gypsum raw powder which has reached the required fineness of the product after grinding into the boiling furnace for calcination, and the rest is returned to the mill for re-grinding until it is qualified.
(3) Gypsum powder calcination;
The boiling furnace is a widely used equipment in the construction of gypsum calcining equipment in China. The equipment has simple structure and convenient operation.
(4) Storage and transportation.
The qualified gypsum powder after calcination is sent to the clinker silo for storage or sent to the product workshop for use
