A first survey of grinding with high-compression roller ...

1988-4-1 · A first survey of grinding with high-compression roller mills. Int. J. Miner. Process., 22: 401-412. The special feature of high-compression roller mills (HC-roller mills) is that a bed of particles is compressed between two rollers to a high solid density more than 70% of volume. The size reduction occurs by interparticle crushing.

Grinding - ScienceDirect

1991-1-1 · In the high-compression roller mill, the material is stressed between two rolls. In many versions, the stressing of the granular masses of solid material by means of rollers is used in combination with a classifier. In mills incorporating grinding media, the grinding stock is comminuted by compression and shear between the grinding media.

High pressure grinding rolls (HPGR) - Outotec

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.
