Sag Mill Ballsizing Grinding Classification Circuits

If you have done proper test work and assumed your Work index is as you provided above quickly I can estimate that your SAG throughput is around 517 t/h and if the total % of mill charge is 25 % of the total mill volume, then you can assume the following assumption .i.e. mass proportion of grinding body to ore be 15% steel balls and 10 % ore (1.5:1) this means 1ton/h of ore requires 1.5 tons/h steel ball, therefore …

Optimizing Your Sag Mill Operation International Mining

In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill

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 uneven wear of balls

Ball Mills An Overview Sciencedirect Topics

Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range 1.56–1.64

Quantifying And Improving The Power Efficiency Ofsag

Feb 01, 1994 · SAG mills, on the other hand, rarely approach the efficiency of a ball mill. Breakage mechanisms are not nearly so well defined, and while it is possible to influence breakage rates in the mill by changes in mill speed, ball load, and feed size distribution, manipulation of these variables will often fail to produce a power efficient circuit

See Figure 1. With a CLR of 160% the circuit is close to 2.0 times more productive (efficient) than open circuit (0% CLR). Increasing the circulating load to 500% brings that value up to 2.6 times, for a further relative productivity increase of 30% (2.6/2.0 =1.30). And all this is achieved with the same ball mill …
