2019318ATOX 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

Live ChatProduction normally takes place in a coke battery located near an integrated steel mill. In the battery coke ovens are stacked in rows. Coal is loaded into the ovens and then heated in the absence of oxygen up to temperatures around 1100 degrees Celsius 2000 degrees Fahrenheit. Without oxygen the coal does not burn it begins to melt.
