Coal Mill an overview ScienceDirect Topics
In wall firing, the fuel is mixed with combustion air in individual burners. Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat’s flow-shaping contour, enables recirculation patterns that extend into the
ATOX coal mill SKD
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

To stop recirculation, pumps without a wear ring feature close the suction-side impeller clearance by adjusting the impeller to the suction side. This can be effective when pumping fluids with no solids; with slurries, however, as the pump wears the solids become caught between the rotating impeller and static suction liner, and are crushed.
