Vertical Roller Mill is a new type of grinding mill based on years concentrated design and development by introducing advanced European technology. The processing capacity ( from 1 to 150 ton per hour)of which is very larger than traditional grinding mill. This type of roller mill is designed specially to solve the problems of low capacity and high consumption of industry mills.Vertical mills have adopted reasonable and reliable structure design acting in concert with advanced process which is integrated by drying, grinding, powder separating and elevating, which is able to meet clients’ need well with internationally advanced technological and economical indexes and can be adopted in cement, hydroelectric construction, metallurgy, chemical, and non-metal ore grinding, especially in large scale grinding or various ores of lump and grain shape into powder.
Technical Data :
Mm to inch conversion: 25.4millimeters=1 inch
The humidity and hardness of raw material will affect the fineness and capacity.

Notes:
1. Material should be with hardness less than 7 in Mohs’.
2. Hot air is only necessary if outlet moisture is required to be less than inlet moisture.
3.When grinding material is difficult to grind, please use the largest power.
