High Pressure Grinding Rolls (HPGR) TENOVA

Grinding of material in HPGRs has proven to be more cost efficient as compared to conventional mills and crushers. Especially downstream processing stages such as ball-milling are more energy-efficient due to the finer product size distribution coming out of the HPGR and the additional effect of micro cracks in the HPGR product particles.
