Gypsum is a widely used industrial material and building material. It is a hydrate of calcium sulfate (CaSO4). Natural gypsum is non-toxic, harmless and non corrosive to human body. Gypsum powder mixed in the building process is also a natural inorganic material. The environmental friendly mineral powder can be obtained by grinding gypsum in the grinding machine. What are the uses of gypsum grinding powder? Gypsum grinding equipment and process flow, you can learn more from this article.

一、 What are the uses of gypsum powder?

1. Gypsum powder can be used as gel material; Gypsum powder is known as one of the five gel materials. In the concrete industry, gypsum powder is used as a Portland cement retarder and an indispensable additive in the concrete industry.

2. Gypsum powder can be used for building decoration; For example, the putty powder used for building walls, pointing and wall leveling is mainly composed of gypsum powder, which is divided into "anhydrite" and "anhydrite". Another kind of colored gypsum powder can also play a decorative role, and the cost is relatively low.

3. Gypsum powder can be used as the main raw material of concrete expansion agent, anti crack agent and self leveling mortar, and as the composite mineralizer in the production of special cement.

4. Gypsum powder can also be used to produce gypsum building materials, such as plastering gypsum, plastering gypsum, gypsum mortar, gypsum powder, gypsum board, gypsum partition board, fiber gypsum board, building standard bricks, etc.

二、 Introduction to gypsum grinding equipment and process flow

The common equipment for gypsum grinding mainly includes the following:

1. Jaw crusher

Jaw crusher is mainly used for coarse crushing of various ore materials, which can crush large blocks of gypsum into small pieces that can enter the mill. Jaw crusher has the characteristics of stable operation, high yield, uniform particle size of finished products, economic operating costs, etc.

2. Raymond mill

Raymond mill is an advanced grinding equipment, which is applicable to the processing of various nonflammable and explosive ore materials with Mohs hardness no more than 9.3 and humidity below 6%. It can grind more than 200 kinds of ore materials. High passing rate, fine mesh, and the finished product is in the range of 80-400 mesh. The fine mesh of gypsum powder for construction is about 300 mesh.
