Some people hold that the rod mill crusher should be used, because the rod mill has a selective effect on the fines and grinds the gravel in a gradual way. Hence, there is a less over-grinding phenomenon. However, the rod mill crusher has some defects, such as low output, high operation cost, high labor intensity.
