and Closed Circuit AG/SAG Mills S Morrell1 ABSTRACT The aspect ratio (mill diameter/mill length) of autogenous and semi autogenous mills varies widely and can be as high as three or as low as 0.5. The literature on the subject of what effect aspect ratio has on grinding mill performance or energy efficiency is almost non-existent.

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. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

Grinding efficiency would be improved if the SAG mill could be operated in closed circuit without a slurry pool appearing. As the plant at maximum throughput with 2-SAG-2-Ball-Mill circuit is ball mill limited, the improved pulp removal will result in more throughput. A drier SAG mill charge will result in improved grinding efficiency and finer

The two types of ball mill in general use are the grate mill and the open-end mill. Most manufacturers make both kinds; the difference between them is that the grate mill has a steel grid clear across the discharge end, but the open-end mill has only an open trunnion at the discharge end, through which pulp flows freely.
