Answer 2

The efficiency is maximum at the mixed-mode speed of the Ball mill.

• A ball mill is pharmaceutical equipment that is used to grind pharmaceutical components or powders into smaller sizes.
• It works on the principle of contact and abrasion among particles, thus powder particles must come into adequate contact to be size reduced.
• This is entirely dependent on the ball mill's speed.
• In a ball mill, the efficient speed is 2/3rd of its critical point of critical speed, at which the particle achieves its highest point and has partial flight also.
• Due to this speed, both mechanisms are operated and the size is effectively lowered.
