The Vertical Roller Mill is widely used in the fields of cement, electricity, steel, nonmetallic ore etc. It can grind cement raw materials, slag, coal etc. into powder.
Material through the feed tube fell on the center of grinding plate, centrifugal force generated from the rotation of grinding plate uniformly scatters and flattens the materials outwards the surrounding area of grinding plate, to forms a certain thick layer of materials bed, the material was crushed by number of rollers at the same time. Driven by the continuous centrifugal force to keep the materials moving to the outer edge of the grinding plate, the materials off the grinding plate rising with the hot air which enter from wind ring into the mill, through the mill shell into the middle of the separator, in this course materials and hot gas do a fully heat exchange, and the water quickly evaporates. Separator controls the output size of finished product, greater than the specified size are separated and fall back to the plate, while meet the fineness requirements are brought through the separator into the finished product warehouse.
1. High efficiency, low power consumption;
2. Small metal consumption per unit of product;
3. Materials bed grinding, low noise, negative pressure operation, less pollution;
4. Simple technological process, it can grinder, dry, and classify the materials at the same time;
5. Less area occupation, compact layout, less equipment weight and low investment.
