This device monitors your grinding pressure at each of the grinding locations with a load cell. This information is then shown on a display on the side of the mill and/or in the control room. This data will help to calibrate your grinding pressure for proper fineness and thereby control capacity and mill DP. Another benefit is the ability to spread the load evenly across the main bearings.

Material is prevented from spilling over the edge of the dam ring as both the dam ring height and grinding pressure are adjustable. The ATOX® Coal Mill’s efficient separator allows material that has reached the required fineness to leave the grinding mill and sends oversized material back for further grinding.
The situation is further complicated by the ‘mill reject’ streams that reject undesirable material (tramp metal and non-coal bearing rock) from the mill. Generally, the following steps illustrate the path through a VSM: • The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; •
