Ultra Fine Vertical Roller Mill Advantages1.High grinding efficiency: save 20~30% power consumption compared with the ball mill.
2.Strong drying capacity: dry and grind raw materials with moisture content as much as 15%.
3. Mutifunction: crushing, drying, grinding, separating and conveying.
4. Low noises and little dust: no direct contact between the grinding rollers and grinding disc, so metallic impact is avoided and its noises is 20~25 decibels lower. Totally closed negative pressure operation has employed by this vertical grinding mill, so there is little dust during the operation.
5. Low wear rate and little metallic pollution: its metal wear is only 5~10g/t.
