# ball mill charge calculation per size

### Ball Millan overview ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel.

### Optimum choice of the make-up ball sizes for maximum

For the same amount of ball charge the number of balls in the mill decreases as the ball size increases. Thus the S values are lower for larger balls. However larger balls are capable of breaking large particles therefore the size at which the S value becomes maximum x m increases as the ball size becomes larger.
