Where is the mill that can polish the cooked gypsum powder

Gypsum is divided into raw gypsum (also known as gypsum dihydrate, hardness of 2) and mature gypsum (also known as hemihydrate gypsum, hardness of 3~3.5), the main chemical composition is calcium sulfate (CaSO4). Gypsum can be used as cement retarder, gypsum building products, modeling, medical food additives, sulfuric acid production, paper filler, paint filler and so on, it is a kind of widely used industrial materials and building materials. Among them, when it is used to make gypsum lines, gypsum board and other building materials, the fineness of gypsum powder is between 80-200 mesh.

Processing technology:

1. Crushing stage: through the crusher, the raw plaster ore is crushed into small materials to reach the feeding fineness (15mm-50mm) that can enter the mill.

2. Grinding stage: through the feeding system, the crushed small materials are evenly and quantitatively fed into the mill to be ground into powder.

3. Classification stage: the powder is classified by the powder selector, and the unqualified powder is returned to the grinding chamber of the host machine for re-grading.

4. Powder collecting stage: the powder that meets the fineness enters the powder collecting system, which is the finished powder, and is sent to the intermediate bin by the conveying device.

5. Drying stage: The collected gypsum powder is calcined to produce mature gypsum powder. Collected to the aging tank body for cooling, after cooling, it can be packed and transported.
