7take away most of the heat generated in the grinding process. as in creep grinding bum-out of the coolant causes a steep rise in contact temperature of the workpiece. 1 introduction cost quality and productivity in grinding processes are all dependent on energy consumption and process..
The formula to calculate critical speed is given below. n c 42.305 sqtd-d n c critical speed of the mill. d mill diameter specified in meters. d diameter of the ball. in practice ball mills are driven at a speed of 50-90 of the critical speed, the factor being influenced by economic consideration. theory and practice for u. s. stonewa.
Read MoreThe critical speed of a rotating mill is the rpm at which a grinding medium will begin to centrifuge, namely will start rotating with the mill and therefore cease to carry out useful work ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical spe.
