The vertical roller mill (VRM), also known as the vertical grinding mill, is a large-scale powder mill equipment developed by FTM Machinery using advanced powder grinding and external circulation technology.
It can grind materials with Mohs hardness below 8 and humidity below 15%, such as cement raw materials, cement clinker, coal, slag, limestone, iron ore, gypsum, marble, phosphate ore, lithium ore, dolomite rock, kaolin clay, bentonite, talc, graphite, etc.
Vertical Roller Mill
After crushing, the material enters the vertical mill, which grinds based on the material bed principle.
The motor drives the grinding table to rotate, and material falls from the feed inlet to the center. Hot air enters to dry the material by evaporating moisture. Centrifugal force moves the material to the edge, where grinding rollers crush it in the annular groove.
Working Principle of Vertical Roller Mill
1.High grinding efficiency. Hydraulic pressure increases grinding force, improving efficiency. Capacity up to 420 tons/hour.
2.Adjustable product fineness. Flexible fineness from 80 to 600 mesh, meeting diverse production needs.
3.Intelligent control system. Easy operation, stable performance, and low failure rate.
4.Environmentally friendly. Full negative pressure sealing, dust removal rate up to 99.9%, energy consumption reduced by 30%-50%.
