# what is effect of ball size in ball mill

### Ball Millan overview ScienceDirect Topics

where d b.max is the maximum size of feed (mm) σ is compression strength (MPa) E is modulus of elasticity (MPa) ρb is density of material of balls (kg/m 3) D is inner diameter of the mill body (m).. Generally a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.

Get Price### The operating principle of the ball mill

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media as well as a lot of noise. Most of the energy useless lost during ball mill operation leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

Planetary ball mill is a most frequently used system for mechanical alloying since only a very small amount of powder is required. Therefore the system is particularly suitable for research purpose in the laboratory. The ball mill system consists of one turn disc (turn table) and two or four bowls.
