Product Description

High Pressure Grinding Rolls (HPGR) offer several benefits to the minerals industry, such as

· Significantly high overall throughput

· Low energy consumption

· Superior downstream recovery and grindability

· Excellent grading of downstream products

· Low levels of maintenance

· Small footprint

· Low vibration and noise

· Excellent availability due to low wear

· Selective liberation

Operating principle

High pressure grinding is achieved by an advanced type of grinding roll. Contrary to conventional crushing rolls, the particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls.

This particle bed is created between two choke-fed, counter-rotating rolls. Between these rolls, a particle bed is pressed to a density of up to roughly 85% of the actual material density. This compression is achieved by applying high pressure of up to nearly 300Mpa, exceeding the compression strength of the feed material. During this compacting process the material is ground to a wide particle size distribution with a large proportion of fines, compacted into flakes.
