ATOX coal mill. Working principles The raw coal enters the mill via a rotary sluice and feed chute and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers. The coal then continues over the dam
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill built to last, reliable and energyefficient is the optimum solution when it comes to performing several process steps in one unit.

Two factors affecting grindability are the moisture and ash contents of a coal. In general, lignites and anthracites are more resistant to grinding than are bituminous coals. One commonly used method for assessing grindability is the Hardgrove test, which consists of grinding a specially prepared coal sample in a laboratory mill of standard design.
