Answer 2

Optimum Speed.

In Ball mill maximum size Reduction is obtained at optimum speed.

Explanation:

• A ball mill is basically  used in mining purposes for grinding or blending the materials.
• The reduction in the size takes place as the ball drops from near the top shell. It is usually 0.5 cycles per second.
• So the maximum size reduction is obtained at optimum speed as the dropping from top shells take place gradually.
