Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heat-sensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. ... Media wear is much less than an SAG circuit in terms of total volume (balls and liners) or as unit …

Improve grinding throughput, while lowering operating costs and complexity with HPGR Pro, the latest generation in high-pressure grinding roll technology. The HPGR Pro Grinding mining solution is engineered to …

High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis. This makes HPGRs more …
