Coal mill is an important auxiliary equipment for coal-powder furnace, it has three methods to crush the coal lump and grind them into powder,it is crushing, impacting and grinding. Air swept coal mill is the main equipment in cement plant for both drying and grinding of the powders. Compared with the ordinary ball mill, it has advantages of higher capacity, more convenient operation, safer usage, and more reliable performance. Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as ball mill or vertical mill can pulverize the coal into particles.
1. Higher yield;
2. Convenient operation;
4. Reliable performance
each bearing are using a No. 1 MOS2 grease or ZM - 2 sodium grease lubrication, roller bearing refueling once every two classes, the host bearing refueling once every four classes, blower bearings refueling once every month. Bearing temperature rise to a maximum of 70 degrees Celsius, was found to be breaking the bearing overheated bearings and bearing chamber cleaning accessories such as cleaning once.
