Ball Mill Maintenance & Installation Procedure
The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill.
coal pulverizer operation - walkingonwaterfl.org
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 ...
Raw Coal Spillage Or "Pyriting"
Low journal spring pressure or broken springs. Improper setting of "button" or spring pressure seat clearance. Worn grinding elements. Seized journal bearing that results in "plowing". Overfeeding of the mill. Pulverizer throats that are not properly sized or have been enlarged by wear may result in serious coal dribble or spillage.
