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.

High-pressure grinding rollers (HPGR) During the high-pressure comminution process, rather than being crushed between the roller surfaces, individual grains or particles are in effect compacted to a dense flake through exposure to relatively high pressures. Following de-agglomeration, the flake normally shows a substantial amount of completed or incipient …

Roller press is a highly efficient communication system where the feed material is exposed under a very high grinding pressure between two solid rollers [ one fixed and one moving ] for a short time due to compression. The high pressure causes formation of micro cracks in the feed material and generates a substantial amount of the fine material.

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 (HPGRs) have struggled for acceptance into the hard-rock mining sector. HPGR roll diameters typically range from 0.5 m to 2.8 m, depending on the supplies, and roll widths vary from 0.2 m to 1.8 m. The aspect ratio of the rolls also varies as a function of manufacturer. Typical HPGR throughput rates range from 20 to ...

HPGRs can handle a wide variety of ores and particle sizes, from fine pellet feed all the way up to coarse grinding of 75mm magnetite iron ore. Alongside their greater tolerance for ores of different hardness and variable roller speed, HPGRs promote greater flexibility in feed conditions and circuit design than traditional mills.

If HPGRs are operated correctly, ball mills can be downsized and use smaller grinding media, which substantially reduces steel ball consumption, increases the grinding efficiency and lowers operating costs of the milling substantially. The use of HPGR technology also promotes micro fracturing, which can expose minerals encased or locked within a particular ore.
