Future-proofing your grinding circuit with dry HPGR .Traduire cette page

Moreover, dry grinding by HPGR prevents oxidization of particle surfaces and introduces less grinding media contamination into the process compared to conventional grinding, which in turn enhances mineral recovery. In a market where many believe "water is the new oil," utilizing HPGR and dry classification technology can go a long way to future-proofing your grinding circuit.
