mar 02, 2021 ball mill is mainly used for grinding in mining cement, refractories, chemical, power plant, aluminum ,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy. energy saving andhigh efficiency ball mill is driven by rolling bearing, compared with ordinary
figure shows the averages of net energy consumption per each mill in the regrind circuit on a monthly rate. the data was obtained from the automatic control system of the circuits. As can be seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit.
grinding media on power requirements and energy consumption of a ball mill. with constant mass of the steel balls the agitator shaft speed was increased from to 100% of the maximum speed, which corresponds to a speed of rpm. the power consumption was recorded upon which milling energy consumption
