Use of Gypsum Powder
Gypsum powder is one of the five major gel-type decorative materials. It is widely used in many industries and application fields such as construction, building materials, industrial molds and art models, chemical industry and agriculture, food processing and medical beauty. It is a very important The industrial raw materials are usually white and colorless, and sometimes they may become gray, light yellow, light brown and other different colors due to impurities.

Gypsum powder mainly has the following applications:

1, Building materials and construction industry
a: Anhydrite cement and cementitious materials: Anhydrite cement or cementitious materials can be produced by adding an appropriate amount of activator, suitable for the reinforcement of soft soil foundations, wall painting, mechanical models, tunnel support and production of fiber pressure boards .

b: Used as a co-solvent and scavenger in the glass production process.

c: Used as filler in industrial production of plastics, rubber, coatings, asphalt, linoleum, etc.

d: Cast-in-place piles and deep stirring piles are used as large expansion materials to increase frictional resistance.

2, chemical industry
a. used for the production of sulfuric acid, with the production of light cement.

b. used for the production of ammonium sulfate, with the production of light calcium carbonate.

3, agriculture
a. Improve the soil, adjust the pH, suitable for soil improvement such as saline-alkali land and red soil.

b. used as calcium and sulfur compound mineral fertilizer in the cultivation of edible fungi to adjust the pH of the medium.

c. used as compound mineral feed additive in poultry and livestock feed.

How Gypsum is Processed?

The gypsum grinding process is mainly divided into four stages.

The first stage is crushing: The large pieces of gypsum material need to be crushed by the jaw crusher to the fineness that can enter the grinding mill.

The second stage is grinding: The crushed gypsum material is sent to the gypsum particle silo by the bucket elevator, and then evenly sent to the grinding chamber of the gypsum mill by the vibrating feeder for grinding process.

The third stage is classification: The pulverized materials are classified by the powder separator, and the unqualified powder is classified by the powder separator and then returned to the mill for re-grinding.

The fourth stage is calcination: The gypsum raw powder with the required fineness after grinding is sent to the boiling furnace for calcination by the powder separator, and the qualified gypsum powder after calcination is sent to the clinker silo for storage or sent to the product workshop for use.
