Modelling SAG milling power and specific energy

Chilean copper concentration plants are used and the % 600 +100 ( 152 +25 mm) is selected as indepen- firstly predicted using the SAG mill feed F80 and the ball mill cyclone overflow P80. Morrell’s model (Morrell, 2011) relates the Pc = SAG mill power consumption (kW); % 600 +100 = % of the fresh feed in the size range 152 +25 mm.

Modelling SAG milling power and specific energy

Jan 01, 2015· The ball charge is a function of the bulk fraction of the SAG mill volume (Jb) occupied by balls; the ore retained in the mill is the result of the volumetric filling which depends on the ore size distribution (specially the % +6″ and the % −6″ +1″), on the rotational speed (N/Nc) and on the solid concentration by weight fraction inside

Power to the pits Canadian Mining JournalCanadian Mining

The rod mill and ball mill combination uses motors that ranges from 2400 hp to 5000 hp. The semi-autogenous grinding mills use motors up to 15,000 hp followed by ball mills driven by 4000 hp to 5000 hp motors. The new style sag mill process being proposed for new mines may use up to 28,000 hp using wrap around motors to drive the mills.
