What Is Gypsum

Gypsum is an important building material used by architects and builders around the world. Gypsum generally refers to two kinds of minerals: raw gypsum and anhydrite. Raw gypsum is also called dihydrate gypsum, hydrated gypsum or soft gypsum, and is usually dense.


Uses Of Gypsum Powder

With the rapid development of the national economy, gypsum has been widely promoted and applied in different fields. Gypsum powder can be divided into the following 4 aspects according to its uses:

1. Gypsum powder uses in construction and building materials: the plaster gypsum obtained by calcining gypsum to 170°C is used to coat ceilings, wood boards, etc.; gypsum can be used as cement and cementing materials in plastics, rubber, coatings, asphalt, linoleum and other industries Used as a filler in production; it can also be used as a coagulation and expansion agent, anti-cracking agent, and the main raw material for self-leveling mortar.

2. Gypsum powder uses in chemical industry: gypsum can be used to produce sulfuric acid, along with the production of light cement; it can produce ammonium sulfate, along with the production of light calcium carbonate. 

3. Gypsum powder uses in agricultural field: gypsum can be used to improve the soil and adjust the pH; it can be used as a calcium and sulfur compound mineral fertilizer in the cultivation of edible fungi; it can be used as a compound mineral feed additive in poultry and livestock. 

4. Gypsum powder uses in thermal power plant field: With the continuous increase in environmental protection, the role of gypsum in thermal power plants has become increasingly prominent. In the desulfurization process, choosing a good desulfurizer is the key to absorbing sulfur dioxide, and limestone can be used as an efficient desulfurizer For use, the smaller the particle size of limestone powder, the more conducive to the absorption of sulfur dioxide, and the more efficiently and quickly the flue gas after combustion can be desulfurized and purified. 

Gypsum Powder Production Process

How Is Gypsum Processed

To get the gypsum ore into a state where it can be sold for its many uses, it is crushed to size using jaw crusher, cone crusher or impact crusher and stockpiled to await further processing.

The crushed gypsum is screened using vibratory screens to separate the sizes for their different uses. One size from the screen may be sold as a cement retarder, while another size may be stockpiled for further processing. Further processing includes drying the ore to remove excess moisture, then grinding it into a fine powder known as land plaster. 

The First Stage: The Crushing Of Raw Materials 

The gypsum material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill. 

The Second Stage: Milling

The crushed gypsum pieces are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

The Third Stage: Classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding. 

The Fourth Stage: The Collection Of Finished Products 

The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow.The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged by a powder tanker or an automatic baler.
