HPGRs for Low to High Tonnage Applications

Why HPGR? The energy-efficiency of crushing and grinding is an increasingly important issue across all processing industries requiring comminution or size reduction of material. Today, high energy costs coupled with the worldwide initiative to reduce CO2 emissions have made state-of-the art HPGRs indispensable in many processing industries.

Plant and Machinery

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. After de-agglomeration, the flake normally shows a substatial amount of completed or incipient …
