High-pressure mill - HPGR series
High Pressure Grinding Rolls (HPGR) are considered to be the most preferred machine ideal used to grind cement and limestone. Since its inception in 1984, HPRG's have been evolving and applied in mineral manufacturing plants especially in the iron ore and diamond processing. The application range of HPGR includes rough grinding of pebbles measuring 65mm (2.5") in AG passage loops and final stage grinding of less than 100μm material.
Using the HPGR grinding technology, you can create huge volumes of the final product with less bond work index of materials. This leads to a decrease in the predicted amount of equipment units used in third and fourth stage crushing and grinding work.
