    30/08/2019· When the ball mill cylinder is rotated, there is no relative slip between the grinding medium and the cylinder wall, and it just starts to run in a state of rotation with the cylinder of the mill This instantaneous speed of the mill is as follows: N0 — mill working speed, r/min; K’b — speed ratio, % There are many layers of grinding media in the mill barrel It is assumed that theto coarse material (kW) x Mill grinding rate of coarse material (t/kWh) (1) The power applied to mill speed are used to calculate the energy input The specific energy input (E, in kWh/t) is the energy input divided by the mill solids load The energy specific cumulative grinding rate (k) at each particle size is then calculated from the test feed and product size distributions using theBall mill media optimization Metcom TechElectric Motor power consumption calculator: Choose the rated capacity of the motor in W, or kW or HP and percentage of load and operating time in hours Then press the calculate button, you see the total energy consumption of the motor Our Calculator suitable for all the loads such as DC moto, singlephase motor and threephase motorElectric Motor Power Consumption Calculator & 3 Phase
