High Pressure GrindingRolls - The economical Solution for the Miningand Mineral Processing Industry

Energy saving processes and technologies within the mining and minerals processing industry are gaining increasing attention. Since its introduction in 1985, high pressure comminution with roller presses (also known as HPGR) has been proving its significance in energy efficient crushing and grinding circuits in the cement industry. In more recent times, HPGR technology with its technical and economical advantages has not only carved a niche in the process of diamond liberation but has gradually caught the attention of hard ore miners worldwide.
Operating experiences and collected data indicate substantial advantages in energy savings, material throughput capacities and product quality of HPGR technology versus traditional
crushing and grinding equipment. Furthermore, the HPGR process can offer enhanced performance in downstream mineral processing steps such as ball milling, flotation, leaching, thickening and filtration. These effects are mostly attributed to the phenomenon of incipient cracking of particles resulting from high stresses present in the HPGR compression zone.
