Flexible milling and grinding solutions that last
For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
how high pressure grinding rolls works
High pressure grinding rollers (HPGR), also referred to as a roller mill or roller press, pulverize material as it moves between two large rollers rotating in opposite directions or a roller and a flat surface. The rolls can be serrated, toothed or smooth. Hammer mill Impact mills are similar in construction and principal to HSI and VSI
