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

Then the coal undergoes pulverization which reduces the top size to 1/8'' and/or grinding which reduces the top size to 1 mm or less. This handbook examines the intermediate and fine grinding of coal. Four coal grinding devices - three dry, one wet - are discussed with the appropriate ancillary equipment for complete systems.
