Mineral Processing | Mill (Grinding) | Industries

If there is too much material in the mill, the mill will not grind properly, the load will increase further. To avoid this situation mill power and mill load are monitored. Stopping the feed for a few minutes is a quick method to check if the mill is an overload condition. If power increases, then the mill had been overloaded.
