Coal Pulverizer Patented Grinding Pressure Monitor System

This device monitors your grinding pressure at each of the grinding loions 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.
