The wear pattern in high pressure grinding rolls Mineral

The wear rate at different times was measured and the wear pattern was determined. The pattern was concave and the wear on the centre part of the rolls was greater than that at the edges. The wear rate on the tyre surface was higher than on the stud surface. Solutions for maintaining the efficiency of the HPGR due to wear have been proposed.
