### Optimum choice of the make-up ball sizes for …

Fig. 8 shows the optimum composition of the make-up ball sizes for various feed sizes as a function of the size reduction ratio, R. Because mixtures of two balls (50.8 mm and 25.4 mm ball) are always found to be optimum, the results are plotted with the ordinate being the fraction of 50.8 mm balls.

### Mill (grinding) - Wikipedia

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42 (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

### OPTIMAL SAG MILL CONTROL USING VIBRATION & DIGITAL …
