HPGRs consist of two rolls that are
identical in dimension, rotating in opposite
direction at the same speed. The main
grinding action is a result of inter-particle
crushing. Extreme pressure causes the
particles inside the compacted material
bed to fracture into fner particles and also
causes microfracturing at the grain size
level.
