general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.

The grinding circuit consists of a ball mill and cyclones. The grinding circuit will be designed to reduce ore from an 80% passing size of 7 mm to 40 µm. The ball mill will be a single pinion overflow mill, operating in a closed circuit. The mill has an inside diameter of 4.3 m and an effective grinding length of 7.5 m.

A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.

design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings.

Duarte et al. (2009) pursued three main objectives simultaneously: 1) the optimal design of ball mills (the optimal number and net capacity of ball mills to install in the body preparation stage), 2) choosing the best shifting policy, and 3) identifying the optimal scheduling with regard to constraints on workforce and equipment resources. They ...

Mill Sizing: After laboratory and pilot plant testing confirm the feasibility of autogenous or semi-autogenous grinding, it can be used to establish the exact grinding circuit and mill size.In the pilot plant tests, the tare power of the pilot plant mills should be determined before and after each test run. The tare power should be for the empty mill.
