High pressure grinding rolls (HPGR) minevik
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.Онлайн-запрос
HPGR High Pressure Grinding Rolls
The most common HPGR based circuit involves feeding primary crusher product to a secondary crushing circuit with of cone crushers in closed circuit with screens, followed by tertiary crushing with HPGRs, also operating in closed circuit with screens.
