Ball Charge and Grinding Efficiency Metallurgist &

2020-05-15· With very low ball charge (less than 20 %) and low slurry density power draw will increase because of increasing toe angle and also more lifting. Also with low ball charge slurry pool will reduce grinding efficiency. Beside lower ball charge will increase P80 of ball mill because of less number of impacts but mean residence time will increase by lower ball charge because of more volume to occupy.

2020-05-13· Yesterday I calculated the power draw of our ball mill. I attach a graph of it. Is it possible to have calculated mill power draw to be greater than mill motor HP? Calculated mill power draw is 1,509 HP; Mill motor HP is 1,500 HP According to the calculations, at 54% mill volumetric loading, max power draw of 1,796 HP is obtained.
