The gypsum grinding machine processing equipment first uses a Raymond mill (also known as Raymond mill or Raymond machine) to process gypsum particles into fine and ultrafine powders. The processed gypsum powder is suitable for industries such as building materials, cement retarders, gypsum models, handicraft production, food additives, coating processing, medical rubber, and papermaking accessories.

Application and Scope of Gypsum Grinding Powder Machine：

The gypsum mill is mainly suitable for the crushing and processing of mineral products such as metallurgy, building materials, chemical industry, mining, etc. It can separate impurities and crush various non flammable and explosive materials such as hydrated lime, bentonite, talc, gypsum, activated carbon, humic acid, clay, graphite, iron oxide red, soybean cake, compound fertilizer, rare earth, etc. The Mohs hardness is below level 3 and the humidity is less than 6%.

Characteristics of gypsum crusher：

1. The coarsest particle size of the finished product can reach 0.613mm (30 mesh), the thinnest can reach 0.033mm (425 mesh), and a small part of the material can reach 0.013mm (1000 mesh).

2. The Mohs hardness is less than level 3.

3. The dust removal effect can meet the national dust emission standards.

4. Fineness analyzer and impurity separator are easy to adjust.

5. The spindle device adopts a stacked multi-stage seal with good sealing performance.

Structure and Principle of Gypsum Grinding Powder Machine：

This machine is a vertical combination crusher, consisting of a main engine, a fan, a fineness analyzer, a powder collector, a dust removal and air dispersing device, and pipelines.

There are four rows of twelve hammerheads arranged vertically inside the host, and the inner wall is equipped with a high manganese tooth type lining plate. The material enters the crushing chamber above and is subjected to high-speed impact and shear between the hammerheads and the lining plate to achieve the required fineness. Then, after being sorted by a fineness analyzer, it is carried away by the airflow, and impurity particles are discharged from the lower discharge port.

Processing process flow of gypsum powder production line：

The block shaped gypsum is crushed by a crusher, and the crushing particle size is suitable for the feeding particle size of the Raymond mill, with a maximum not exceeding 30mm. The crushed gypsum is lifted by a hoist to the raw material bin, and then uniformly fed into the Raymond mill host for grinding processing by an electromagnetic vibration feeder. The working principle of Raymond mill is to squeeze and grind gypsum in the limited gap between the grinding roller and the grinding ring through the rotation of the grinding roller. The fan air is blown into the grinding chamber of the Raymond mill main machine, and the ground gypsum powder is sent into the analysis machine system (the mesh size that needs to be ground needs to be set first). Through the powder selection work of the analysis machine, the finished gypsum powder will enter the large cyclone powder collector through the pipeline and can be bagged and packaged. The entire Raymond mill equipment adopts sealed operation to reduce dust pollution. The ultrafine powder (larger than the set mesh size) generated during the production process, also known as dust, will be collected by bag filters with a yield of 1-3kg of dust per ton. Under normal rules, it can be ignored.

The main use of gypsum: Gypsum belongs to the monoclinic crystal system, with high cleavage and easy cracking into thin sheets. Heating gypsum to 100-200 ° C and losing some crystalline water can yield semi hydrated gypsum. Alpha type semi hydrated gypsum has good and solid crystallization; β - type hemihydrate gypsum is a crystal with flakes and cracks, with very fine crystals and a much larger specific surface area than α - type hemihydrate gypsum. When producing gypsum products, alpha type hemihydrate gypsum requires less water than beta type gypsum, and the products have higher density and strength. Alpha type hemihydrate gypsum, also known as high-strength gypsum, is usually distilled in a saturated steam medium using a steam pressure vessel; The beta type hemihydrate gypsum, also known as building gypsum, is calcined using a frying pan or rotary kiln with an open device. The slurry of semi hydrated gypsum mixed with water forms dihydrate gypsum again, which quickly solidifies and hardens during the drying process to obtain strength, but softens when it comes into contact with water. Gypsum is the main raw material for producing gypsum cementitious materials and gypsum building products, as well as a retarder for Portland cement. After calcination at 600-800 ° C, gypsum can be finely ground by adding a small amount of lime and other catalysts to obtain hard gypsum binder (also known as gold binder); High temperature calcined gypsum can be obtained by calcining and grinding at 900-1000 ° C. The products made from these two types of gypsum have higher strength than building gypsum products, and the hard gypsum binder has good thermal insulation. High temperature calcined gypsum has good wear resistance and water resistance.
