Roller press HPGR technology solutions FLSmidth

The roller press features two opposing rolls rotating at a relatively low speed. One roll is fixed to the frame of the machine, the other allowed to move against a set of hydraulic rams. Grinding force is provided via hydraulic pumping system and assisted by nitro-charged accumulators. The roller press is designed to operate in choke feed conditions.

High pressure grinding rolls HPGR - Metso

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.
