  • To make the mill more efficient some roll mills are equipped with a system allowing to guarantee a high pressure (10-50 bar) in between the rolls. It is also mandatory for these mills to have a spring system allowing to release the pressure if the constraint is too important ( foreign body for example) and avoid mechanical damages.

  • High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
