Mar 15, 2015· The finer the pellet feed pre-treated by press roller, the lower of reduction swelling degree of fired pellets, which is below than 15%. Reducibility of pellets also increased to 67.18% when the pellet feed is pre-treated by roller press. After pre-treating pellet feed blend, a much rougher surface and more super fine particles were observed.

High Pressure Grinding Rollers (HPGR) Market Size Report, 2018

The KHD Humboldt Wedag Roller Press is available in ten standard sizes ranging in grinding force from 2 to 32 meganewtons. The specific grinding pressure is kept below 7.0 N/mm 2 in order to limit the stress on the rollers (grinding pressure = grinding force/roll diameter/roll width). The pressure between the rolls can be lower

High Pressure Grinding Rolls (HPGR)

A HPGR reduces particles by compressing and crushing the feed between two equally sized, parallel rollers rotating in opposite directions, with a small gap between them. This compresses the feed to 80% of its solid density, where the force of the rollers pushes the rocks against each other and exceeds their compressive strength.
