High pressure grinding rolls HPGR are used for size reduction or rocks and ores They compress the feed material between two rotating rollers one of which is in a fixed position and another roller that is floating The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.Get Price
Ore processing plant means that extracts and purifies some elements in the raw ore through a series of complex ore beneficiation flow and professional beneficiation equipment. The refined concentrate powder is mainly used in metallurgy and industry base.
