An innovative approach for determining the grinding …

Usually, the power of the ball mill pinion shaft was directly proportional to the motor power of the ball mill, and the correlation coefficient was 1.05–1.20. The correlation coefficient 1.20 and equality (18) [ 32 ] were adopted to ensure the safe and stable production of the ball mill, where N e was the motor power of the ball mill.

Working principle and efficient ways of ball mill

Working principle:When the ball mill works, motor and speed reducer transmit torque force to big and small gears of Ball Mill, so the barrel rotates. When the barrel rotates, Steel balls or other grinding media in the barrel are lifted to a certain height and fall down freely, so materials in the barrel are impacted.
