    Check your mill to confirm that the grinding roll or spring frame preload pressure is set correctly. Our experience with both RP and MPS pulverizers has been that mills designed for a throughput of about 120 000 pounds of coal per hour an HGI of about 45 to 50 and coal fineness exceeding 75 passing 200 mesh will require about the same force on the grinding elements.

    A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer the output will be higher than base capacity and below 50 HGI the output will be lower. The total moisture in coal has a high effect on mill output.
