Steel Ball Consumption In Ball Mill

Aug 01, 2001 Grinding media consisting of steel balls, with typical diameters from 25 to 75 mm, is already present in the mill along with any rock that has not yet overflowed through the discharge end. Typical power consumption for a 5-m diameter by 7-m-long ball mill is between 2.5 and 3.5 MW

    Estimating Ball Consumption - Molycop

    Sep 17, 2018 For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new make-up balls periodically charged to the mill

    Predicting Steel Media Consumption - Grinding

    A big majority of people is still using the old Bond equations without asking themselves: do 950 g/t or 1,100 g/t of steel consumption in the ball mills make sense? When we apply our experience from the last 20 years we see right away that steel consumption in the range of 1,000 g/t in a ball mill is not correct, and that is a fact

    The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44- m (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp
