Abstract. If we consider a tube mill with its length equal to 5 to 6 times the diameter, it can be stated that at about a quarter of the length, half of the feed has reached the required fineness; in further grinding this mass will be overground or even agglomerated. The remedy has long been known: the grinding process must be interrupted, the ...

Figure 1 : A single-stage closed circuit grinding mill. The grinding medium used to break the ore may be steel rods, balls or the mined ore itself. A stirred mill is a stationary vertical or horizontal tubular shell that imparts motion to the charge by the movement of an internal stirrer (Napier-Munn et al., 1999).
1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).
