Industrial Gypsum Raymond Grinding Mill Stone Grinder Machine In Quarry
Product Descriptions of Gypsum Powder Making Machine:
1) Raymond mill is a commonly used milling equipment, mainly used for calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, kaolin, cement, phosphate ore, gypsum, glass, insulation materials with Mohs hardness not more than 9.3 degree.
2) Raymond mill for size reduction, fine powder, ultra fine powder grinding with finished products from 100 mesh to 325 mesh . It was ever popular in mining, building materials, chemical engineering and metallurgy industries for size reduction, dispersion, or specialized needs, powder generation and processing for industrial process. Raymond grinding mill is suitable for primary grinding, secondary grinding, re grind applications, fine grinding, lime slaking etc.
Working Principles of Stone Grinding Machine:
1. After the materials enter the grinding chamber of the main frame, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft.
2. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls. After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding chamber for re grinding.

Features:
1. The mill is installed on the ground. The ground part is 50% of the height of the traditional mill.Reduce the height of the factory building, save the investment of the factory building, more conducive to equipment maintenance
2. Grinding roller bearing seal is a new type of seal, which is maintenance-free and oil-free. Eliminate bearing powder, greatly reduce equipment maintenance costs.
3. The hierarchical cavity adopts suspension structure, which can automatically lift and shift to reduce equipment resonance, reduce noise and improve maintenance convenience.
