Vertical Coal Mill
The vertical coal mill manufactured by Haijian is widely used in coal pulverizing system of various industries such as power, metallurgy, building materials, chemical, etc. It is an ideal choice for grinding medium hardness materials like soft coal. Particularly, this bituminous coal grinding machine is largely used in positive pressure direct-firing coal pulverizing system of fuel soft coal.
Apart from low unit power consumption, small floor space, simple system, low noise, reliable operation, etc. similarly featured by general medium speed coal mill, this vertical coal pulverizing mill is also specially characterized by large crushing ratio, long service life of grinding parts, small change of power output in whole operation cycle, wide range of applicability to materials, perfect applicability in both high and low load, etc.
