MEI s Barry Wills The impact of milling costs on total

06 01 2014  It has been shown for example that the replacement of a SAG mill with a HPGR in a conventional SAG ball circuit may reduce grinding energy consumption by 15–20 Taking into account additional savings such as media and liner wear it was found that a grinding cost saving of 25–35 was potentially achievable with the use of HPGRs in such conventional circuits.

Rod mills how they function

Rod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1.4 to 1.6.

Stamp mill

A stamp mill consists of a set of heavy steel iron shod wood in some cases stamps loosely held vertically in a frame in which the stamps can slide up and down They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp the stamp falls onto the ore below crushing the rock and the lifting process is repeated at the next pass of the cam.
