These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semi autogenous ball-mill-crushing circuit, and the application is well described. This refers to high-aspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.

Jul 17, 2020. These large coal crushing drive systems are usually rotated by motor-driven gearing. A typical application consists of a motor-driven primary single-stage reducer that, through a flexible coupling, drives a large open pinion which in turn, meshes with a large ball mill ring (girth) gear that is attached directly to the ball mill

SINGLE STAGE BALL MILLS Single stage balls add to the argument that rotary mills are not effi cient when processing large hard material. If a single stage ball receives material of 80 per cent passing 6 mm and larger, then the Bond oversize ineffi ciency factor EF4, will apply even if the material has rod and ball mill laboratory work indices as

It also gives an improved residence time distribution for the material, since a single stage ball mill approximates closely to a completely mixed system. In wet grinding the power consumption is generally about 30 per cent lower than that for dry grinding and, additionally, the continuous removal of product as it is formed is facilitated.

Further, either SAG or AG mills can be operated in a stand-alone mode (single-stage) or coupled to a ball mill in FAB or SAB configurations (Gupta and Yan, 2016). The size distribution of the fresh feed as well as the ball size distribution are also known to have important effects in the process ( Napier-Munn et al., 1996 ).

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
