Dolomite Ultrafine Vertical Grinding Mill , Non-Metallic Powder Vertical Roller Mill , With Adjustable Fineness
1, Introduction to Vertical Dolomite Mill
Application field of dolomite powder production
Dolomite powder can be used as a refractory inner layer, slag making agent, cement raw material, glass flux, kiln industry, fertilizer, building and decorative stone, paint, insecticide, and medicine for various purposes in the conversion furnace used in steelmaking. It can be used in fields such as building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy conservation, etc. Mainly used as alkaline refractory material and flux for blast furnace ironmaking; Production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; And ingredients for producing glass and ceramics.
Material processing
Hefei Hengcheng powder making equipment is applied in many fields such as large-scale non-metallic ore powder making, environmentally friendly desulfurization limestone powder making, calcium carbonate powder making, large-scale coal powder equipment, petroleum coke fuel industry, manganese ore processing field, comprehensive utilization of slag, water slag, fly ash, gypsum powder making, etc.
2,Introduction to HVM Type Dolomite Vertical Mill Process
The material discharge pipe falls into the center of the grinding plate, and the constant speed rotating grinding plate uses centrifugal force to evenly disperse and flatten the raw materials outward, forming a certain thickness of material bed. The material is simultaneously crushed by multiple grinding rollers on the grinding plate. Under the continuous drive of centrifugal force, the material continuously moves towards the outer edge of the grinding disc. The material leaving the grinding disc encounters hot gas entering the mill through the wind ring and rises accordingly. It enters the separator through the middle shell of the mill, and during this process, the material undergoes sufficient heat exchange with the hot gas, and the water is quickly evaporated. The powder concentrator controls the fineness of the finished product at the outlet of the roller mill. Particles larger than the specified size are separated and fall back to the grinding disc. Materials that meet the fineness requirements are fed into the finished product warehouse through the powder concentrator.
