The hammer mill is made up of a steel drum that houses a shaft of many hammers. This type of mill is often used as a secondary or tertiary crushing method to achieve the desired results, but can also be the primary mill when called for. The hammers are spun at high speed as the material enters the drum.

A brief description of the SAG and HPGR circuits is given below. As part of the evaluation, it was decided to focus the trade-off study on replacing the conventional SAG mill in the comminution circuit with an equivalent duty HPGR unit. Other potential circuit configurations utilizing HPGR were not considered in the study. 4.1 ASSUMPTIONS
HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant. By adding a Polycom high-pressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power ...

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.
