The starting point for ball mill media and solids charging generally starts as follows: Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading. Empirical Check: Once the mill has been loaded and run for a few minutes, open the cover and look down into the mill.

Grinding Machine Disadvantages: The following disadvantages of Grinding Machine are: The Grinding Machine is a little costly. The cost of this machine is more than 2.5 lacks. Unlike another machine (Lathe Machine) the material removal rate is not fast. It takes more time for removing the material.

A grinding machine is a tool or piece of equipment used for removing material from a workpiece via abrasion. They typically employ rotating abrasive wheels to shape, smooth, or finish workpieces through grinding. The machining process uses abrasive particles to remove material from a workpiece's surface.

ball charge is close to 95 kg (209 lb), occupying 34 percent of the mill volume. Balls are used that represent a fully graded charge based on constant wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent ball charge. The drive shaft is torque-metered and records once per second.
