Want to control grinding mill feed, Automatically?
This early method of determining mill conditions, though well founded, was often inaccurate and manpower intensive. By utilization of more suitable sound sensors, excellent grinding process control is achieved. The sound emanating from the grinding mill consists basically of frequencies in the 100 100,000 Hz range.
Coal Pulverizer Patented Grinding Pressure Monitor System
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.
