Gypsum Uses And Gypsum Mining Process

What Is Gypsum

Gypsum, whose main component is calcium sulfate, generally refers to the two minerals of raw gypsum and anhydrite. Gypsum is the gypsum stone stored in nature, mainly dihydrate gypsum and anhydrite. my country's gypsum resources mainly include ordinary gypsum and anhydrite Gypsum, of which anhydrite accounts for more than 60% of the total, and the first grade gypsum, which is an excellent resource, only accounts for 8% of the total, of which fiber gypsum only accounts for 1.8% of the total. Gypsum is a widely used industrial material and building material. It can be used in cement retarders, gypsum building products, model making, food additives, sulfuric acid production, paper fillers, paint fillers, etc.

Usage Of Gypsum

Gypsum has relatively rich application value. It is popular in many fields such as construction, building materials, power plant desulfurization, food, medicine, etc. The application of gypsum in my country is mainly reflected in the following aspects: 84% is used as a retarder for cement production, 6.5% is used for ceramic molds, 4.0% is used for gypsum products and wall materials, and 5.5% is used for chemical and other industries. With the deepening of the use of gypsum milling equipment, application of gypsum powder continues to expand, which, building plaster and gypsum production line production line value.

1. Building Gypsum: Gypsum is very popular in the field of building materials. The building gypsum products manufactured by gypsum grinding equipment have good fire resistance and are a building material that is deeply loved by construction projects. The gypsum production line produced by Hongcheng meets the requirements of energy saving and emission reduction. , Covering a number of patented technologies, effectively produced powder, is a wise choice for gypsum powder customers.

2. Power Plant Desulfurization Gypsum: Desulfurization gypsum is a by-product of the widely used limestone power plant desulfurization process. Its processing value is very high. The use of a professional desulfurization gypsum production line can enhance the application value of the by-product desulfurization gypsum. Among them, limestone-gypsum wet method is used. The desulfurization process is technically mature and widely used. Only limestone wet desulfurization gypsum is easy to use. Desulfurization gypsum has very superior properties and is a good raw material for the construction industry. It is relatively mature in domestic and foreign applications.

Gypsum Powder Production Process

The first stage: the crushing of raw materials

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

The second stage: milling

The crushed small 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 through the discharge port by the conveying device, and then is packaged by a powder tanker or an automatic baler.

Vertical mill: Large-scale equipment, high output, can meet large-scale production. The vertical mill has high stability. Disadvantages, high equipment investment costs.
