ball mill. This is evidenced by the lower gradient of the size distribution (in log-log space) and the smaller exponent in the power function, hence larger fractal dimension (Turcotte, 1986). This effect is similar to a SAG mill (although to a lesser extent) and results in the P80 being an ineffective measure of the degree of size reduction.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
