1. Coal vertical roller mill can handle all types of coal
Coal vertical roller mill is used for grinding and drying all types of coal.
2. Reducing the power consumption of the raw material preparation effectively
According to the display of material production measured data, it can be saving electricity above 30% use of vertical roller mill production per ton raw material than traditional ball mill, and power saving effect is very remarkable.
3. Finished product has high quality
Coal vertical roller mill adopts advanced technology, finished product has high-efficiency distribution and excellent combustion performance.
4. Floor space is smallest
Due to its structure features, coal vertical roller mill, compared with the same specifications, can reduce floor space and floor use-cost greatly than ball mill.
The material through the feed tube fell into the center of grinding plate, and then the materials outwards the surrounding area of grinding plate at centrifugal force, to forms a certain thick layer of materials bed, at the same time material was crushed by number of rollers. The materials continuous moving to the outer edge of the grinding plate, off the grinding plate materials rising with the hot air which enter from wind ring into the vertical roller mill, through the vertical roller mill shell into the middle of the separator, in this course materials and hot gas got a fully heat exchange, the water quickly evaporates. Separator controls the finished product output size, greater than the specified size are separated and fall back to the plate, while meet the fineness demands are brought through the separator into the finished product warehouse.
