Coal Pulverizer Pall

Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating facilities. In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing the pressure required to pulverize the coal. Raw coal enters the top of the pulverizer through the raw coal

Coal Mill an overview ScienceDirect Topics

The ground coal is picked up by an air stream entering the mill through a Port Ring on the periphery of the Grinding Table; Air entering through the Port Ring creates a fluidising zone in which ‘heavy material’ (Mill Rejects) such as rock falls through the Port Ring into the Air Plenum below the Grinding Table and is ejected from the Mill through the Mill Reject System;

Mill Speed an overview ScienceDirect Topics

In the ball-and-race mill (Fig. 13.3), balls are held between two races, much like a large ball bearing. The top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.

coal mill Mill (Grinding) Screw

It is driven by a planetary gearbox. The three grinding rollers, mounted in fixed position, are passed down on the table under hydraulic loading. Raw coal enters through the center of the mill and is deposited on the grinding table. Centrifugal force feeds the coal radially outward where it is ground between the roller tyres and grinding track.
