Hpgr High Pressure Grinding Rolls Weir

Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80 of its solid volume, exceeding its.

Hydraulic Press with Regenerative Circuit. This example shows the difference in performance of a regenerative hydraulic circuit and a non-regenerative circuit when used in a material press configuration. Both hydraulic systems will be used to press a material with deformable properties and the difference in performance can be compared. A single rod cylinder moves slower when extending.
