Phantom cyclone - SAGMILLING.COM

Phantom cyclone effect SAG and AG mills produce more fines, as a proportion of the whole particle size distribution, than more classical comminution machines such as rod mills. This causes a problem for power-based models because only a single point (the 80% passing point) is used as a proxy to represent the whole particle size distribution ...

Moreover, there are reports of additional cracking within the matrix of the rock (microcracking), but that effect is probably similar to the phantom cyclone effect for modelling purposes. The reported reduction in ball mill operating work index due to these effects is in the range of 5% to 10% versus a laboratory ball mill work index determination.
