hpgr roll crushing experience

Interparticle comminution is theHPGRspecific grinding process in which material particles arecrushedand ground within the compressed material bed and not by contact with theroll surface. Feed material can be smaller than the gap, which is an important distinction as compared tocrushers, for example.

A further aspect ofHPGRforcrushinguntreated pebbles would be that, as therolldiameter of nowadays HPGRs would be sufficiently large enough to accept the pebble particle sizes of up to 90 mm
