The OKTM Mill’s flexible design makes it possible to operate it with a number of rollers out of service while still reaching 60 to 70 percent of the normal operation output, minimising production losses. The compact and long-lasting ATOX Coal Mill has the capability to grind virtually all types of raw coal, to your desired fineness.Jun 02, 2017 A non-linear mathematical model for a normal mill grinding process was developed in the previous work , which was based on the following assumptions: (1) the pulverizing mechanism in the mill is simplified, and coal classification is not considered; (2) grinding and pneumatic transport in the milling process are separated into two stages; and (3) coal size is grouped into only two categories, namely pulverized coal and unpulverized coal.

From the fluidising zone the ground coal is lifted up inside the Mill Body. Larger particles of coal reach a terminal velocity at which gravity will pull them back on to the Grinding Table for regrinding (Elutriation); • The fine coal particles are transported to the Classifier through a set of Inlet Vanes; •The work carried out by the coal mill is relatively heavy, so it will suffer more losses. If these faults are not solved in time, they may cause some more serious problems. It is very vital to do a good job in the maintenance of the coal mill. Common Faults Of Coal Pulverizer.
