The difference in open-circuit PSD is somewhat more pronounced at the longer retention time. The overall residence time distribution in the closed-circuit mill is totally dominated by the hydrocyclone recycle. Thus, a heavily recycled system becomes in effect a backmixed system and local material transport (through the mill) is insignificant …

Section snippets Mathematical model. In a series of open circuit tests reported by Dorr and Anable (1934) limestone was ground at various feed rates in a 3 ft ball mill.The production of fine material (final product) increased with increased feed rate, and the relationship is a straight line in log–log space.

Figure 8.2 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal set-up as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure 8.3 shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the …

open circuit SAG mill, 2. closed circuit ball mill. The Australian experience of milling lateritic ore is to use a high-aspect ratio mill at the initial stages of operation using a single-stage circuit. With time, as the hardness of the ore increases with depth in the mine, a second-stage ball mill is added.

The original method was to pass the ore straight through the primary mill without classification (open circuit) to a secondary circuit similar to the arrangement of Fig. 9 (closed circuit). Greater efficiency in grinding is now obtained by adding a classifier to the first stage so as to convert it into a closed circuit.
