Demerits: 1. High Energy Consumption: Ball mills often require high energy input for the grinding process, making them less energy-efficient compared to some other milling techniques. 2. Wear and Tear: The grinding media and liners experience wear, requiring regular maintenance and replacement. 3.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

The reasons why the planetary ball mill is difficult to be put into large-scale application are that the mass of the tank will necessarily increase and the energy consumption will be huge. Planetary ball milling mainly relies on the centripetal force generated by rotation to drive the movement of balls [11].
