How Energy Efficient is HPGR? CEEC (Coalition for Eco

In mining and mineral processing operations, energy is often the most expensive cost item. Comminution, i.e. grinding, is frequently the most energy intensive step between mine and metal. High pressure grinding rolls (HPGR) are being installed in a rapidly growing number of quot;hard rockquot; mineral processing operations.

HPGR High pressure grinding roll for the minerals industry

During its relatively short history in minerals processing, HPGR technology has undergone significant development in machine roll wear surfaces and control philosophy. Initially introduced as a cement industry product in the mid 1980s, HPGRs soon gained a (minerals processing) foothold in dia mond mines. By the late 1990s the HPGR became standard equipment for processing iron ores.
