One of the most used tumbling mills is the ball mill. This paper reviews different types of grinding media that have been developed and improved over the years and their properties.
High temperature of the ball mill will affact the efficiency 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded Reasons
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …

When an inching drive is in use, the mill motor needs to be disabled, as it can drive the inching drive motor to destruction. This is why starting the mill motor when an inching drive is connected should be prevented. Similarly, when a mill is not being inched, the inching drive needs to be safely decoupled from the main drives.
The drive enables the mill to run on the utility at fixed speed for optimum efficiency or in the event of malfunction of the LCI. Drive Reliability. The gearless drive is probably the most reliable of all drive options mentioned herein. Elimination of gears and motor bearings remove these items from the list of potential problem areas.
