High Pressure Grinding Rolls Applications

High-pressure grinding roll (HPGR) technology was first introduced on an industrial scale in the mid-1980s for the grinding of clinker and raw material in cement making. Notwithstanding early difficulties as would be expected with any new technology, HPGRs quickly proved to be a very economical addition for comminution processes because of lower energy consumption and easy integration into existing conventional systems for capacity enhancement.

Subsequent to successes in cement making, HPGRs soon began to be utilized in a variety of applications in the mining industry to reduce power consumption, increase product yield, and add production capacity in existing milling systems. With regard to abrasive wear, material properties, and selection of process parameters, the natural materials used in mining pose much greater challenges as compared to the relatively constant artificial product, cement clinker.
