Comparison of grinding characteristics in high-pressure

Comminution in HPGR is a result of high inter-particle stresses generated when a bed of solids are compressed while moving down the gap between two pressurized rolls. The priority that HPGR can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semi-autogenous (SAG) mills.

A Review of the Modeling of High Pressure Grinding Rolls

An HPGR machine consists of a pair of counter-rotating rolls, which are mounted in a very sturdy frame. While the bearing block of one roll is fixed, the other one can float linearly to adjust the gap between the two rolls as the material properties, such as particle size distribution, moisture, and hardness, change.
