• ### Circulation Load vs Fresh Feed with Example Minerallurgy

Feb 26 2021 The circulating load ratio is necessary to determine the capacity of the ball mill initially. Once the ball mill is installed you cannot change its capacity The underflow is circulated into the ball mill as shown in the figure The underflow is not a waste; it is further sent to the ball mill operation for further recovery of the.

• ### CALCULATION OF THE POWER DRAW OF DRY

Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.
