Rotation of ball mill,is to use synchronous motor by coupling to make small gear rotate,and fixed on the cylindrical shell big gear to make cylinder rotate.Grinding fine materials output with slurry by out-feed small holes on the board,out-feed end slurry surface is lower than middle spindle neck slurry effluent face,lower than low level,forced discharge.
Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is “pumped” out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber
Type CHRK is designed for primary autogenous grinding, where the large feed opening requires a hydrostatic trunnion shoe bearing.
