HPGR also promotes micro fracturing to expose minerals encased within the particular ore which increases liberation via recovery. Express Frame The frame is a fabricated and machined steel welded assembly consisting of upper and lower sections with a pinned gable end section.
HPGR will be the better performer when you have a very consistent ore body as that machine can be specifically set up to maximize the greater ore quantities. It is when the ore body feed to processing has a wide range of ore variations that fast processing adjustment and flexibility is demanded. Then SAG takes the lead.

minerals processing applications. The use of HPGR machines in minerals processing plants requires special attention to these issues: » Pilot plant HPGR tests are necessary to evaluate the ore performance and to assess process and energy effiencyci » Careful assessment of ore body and definition of best/ worst-case scenarios
Micro cracks present in particles input to the ball mill are not exclusively due to HPGR action. The ore before entering an HPGR, even before excavation, may have some micro cracks. In the HPGR product, there were many micro cracks at the vicinity of cracks.
applications of heap and dump leaching is often in conjunction with a mill. High-grade ore goes to the mill, and lower-grade ores and proto-ores are sent to the heap- or dump-leaching facility. Improving the leach recovery through the application of HPGR would raise the grade cut-off for ore optimally going to the heap or dump leach.
