Optimization of mill performance by using SciELO

2015. 4. 16. Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs. (Figure 7.)



• Reducing the ball size in SAG m ill from 5 to 4 inches balls; • Returning up to 20% of the c yclone underflow back to the SAG mill; • Reducing the cyclone vortex finder f rom 260 to 240mm;


Ball Size effect analysis in SAG Grinding CEEC (Coalition

2021. 3. 27. Ball Size effect analysis in SAG Grinding. Most SAG grinding operations currently use ball size between 5.5 and 6 inch maximum size, However, in most cases the use of these ball sizes hasn't been justified by a phenomenological analysis of the real effect on


Ball Mill an overview ScienceDirect Topics Ball Mills. The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds.


Ball Mills an overview ScienceDirect Topics

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

2021. 4. 4.  A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball

A load expansion is also observed. In an overflow mill, thi s combination of drift. and expansion conducts the ball load to enter the slurry pool with the direct effect of a. better pulp and b all


Ball mill Wikipedia

2021. 4. 2. A section cut thru of ball mills. A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
