Tumbling mills eg AG SAG rod and ball mills Conventional reciprocating crushers eg jaw gyratory and cone HPGRs Tumbling mills are described using 2 indices M ia and M ib Crushers have one index M ic HPGRs have one index M ih For tumbling mills the 2 indices relate to coarse and fine ore properties plus an
Ball limited circuits where the T 80 hits the lower limit will result in the charge level in the SAG mill dropping until its power draw matches the throughput limit dictated by the ball mill It is important to realize that once the SAG mill charge level drops to be equal to the ball charge the model will be operating out of range and the
SAG mills are characterized by their large diameter and short length as compared to ball mills The inside of the mill is lined with lifting plates to lift the material inside the mill where it then falls off the plates onto the rest of the ore charge SAG mills are primarily used at gold copper and platinum mines with applications also in the lead zinc silver alumina and nickel industries

SAG mills use a ball charge of 8 to 21% The largest SAG mill is 42 in diameter powered by a 28 MW 38 000 HP motor A SAG mill with a 44 diameter and a power of 35 MW 47 000 HP has been designed Attrition between grinding balls and ore particles causes grinding of finer particles SAG mills are characterized by their large diameter and short length as compared to ball
SAG mills mimic the same shortcoming It follows that in order to obtain the specifi c energy SE to achieve a certain transfer size based on the 80 per cent passing value an ineffi ciency factor must be applied to the SE of single stage ball mills rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method Rod mill and AG/SAG mill products are similar and
Up until now tumbling mills such as AG/SAG mills and ball mills have had a dominant bearing on the design and economics of comminution circuits However it is commonly agreed that the majority of employed comminution processes are energy intensive and energy inefficient accounting for up to 80% of overall process plant energy consumption and

For the mining industry our semi autogenous SAG grinding mill uses a minimal ball charge in the range of 6 15 percent It is primarily used in the gold copper and platinum industries as well as in the lead zinc silver and nickel industries Autogenous AG grinding mills involve no grinding media as the ore itself acts as the grinding media Our ball mills are the most robust design in
SAG mill control insight and reliability The throughput and efficiency of a SAG mill depends on the volumetric load An overloaded mill has reduced coarse ore breakage as the cascading balls and rock cannot drop far enough reducing kinetic energy for breakage An underloaded mill will break coarse ore well but at the expense of added grinding ball consumption and increased risk of
