Grinding Pressure Of Vrm

Aug 29, 2010 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.
