Key Considerations When Selecting A Mill Lining System
jan 27, 2020 sag and ball mills grind material through different actions and are usually applied in different stages of the process. sag mills usually have a larger diameter than length and are used to reduce large feed size ore down to often qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow. there are backpitch impellers in the hollow shaft, which can make the balls and coarse ores in the overflow return to the mill. with a simple structure, higher operation rate, and rolling bearing, the energy conservation is primary ball mill controls are: mill drive power or mill differential pressure to control mill feed rate. mill sound level to control filling level inside mill with feed rate. mill outlet gas temperature. mill outlet material temperature. cement temperature. outlet gas flow determined from mill inlet and outlet drafts or flow meters installed.
