Aug 15, 2019· In pellet feed application, HPGR is competing with dry ball mills, which consume more energy. Research conducted by the University of British Columbia found the introduction of a HPGR into Can Huckleberry gold mine's mill circuit reduced power usage by 21% when grinding to a P80 of 160 μm, but that increased to 34% when milled down to 75 μm.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Aug 19, 2019· How HPGR compares to conventional milling Whether you're designing a brand-new mill circuit or optimising an existing site for long-term efficiency, High Pressure Grinding Rolls offer a range of advantages over conventional milling techniques, including ball mills, SAG mills and rod mills.
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
Over time, gold and silver prices tend to move in concert, mostly in opposition of depreciating fiat currencies. Recently, the price of gold has been about 60 times the price of silver, while historically it was closer to 20 times. Silver prices tend to be more volatile than gold.
