[5] Autogenous mill Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles.
Abstract and Figures. An increase of over 10% in mill throughput was achieved by removing the ball scats from a single stage SAG mill. These scats are non spherical ball fragments resulting from ...
How HPGR improves gold recovery. There are two main ways mines recover gold ore from the gangue, and HPGRs can assist with each process. One of them is heap leaching and for mines using this process, we've found that the most efficient setup is to have a HPGR perform tertiary grinding immediately prior to recovery, completely avoiding the use of a ball mill with the help of a partial product ...
