HPGR High Pressure Grinding Rolls
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 ...

Ball Clay | Imerys
Ball clays are kaolinitic clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% quartz, as well as organic matter. Ball clay is formed from the weathering and transportation by water of parent rocks. Seams in the same deposit will vary in composition, depending on the quantity of the principal and accessory minerals.
