In this context, sampling campaigns at a real plant were arranged initially and then simulation studies were undertaken by using the pilot scale test results obtained from a dry horizontal stirred mill. Basically, grinding of two different streams, classifier feed and coarse, were considered and necessary calculations had been performed.

Fig. 1 shows the Minas-Rio regrinding plant and Fig. 2 shows the layout of one of the two banks, containing eight VTM-1500 mills and four hydrocyclone batteries. The grinding efficiency of this plant was recently verified through a sampling campaign and the results showed that the measured specific energy consumption was similar to the predicted specific energy …

Stirred milling using either horizontal or vertical mills has made a rapid entrance into PGM ore and tailings concentrator flowsheets. Currently there are 39 units installed in either mainstream, 'MIG' or intermediate concentrate regrind, 'UFG', applications in PGM, primary ore treatment plants, or in tailings scavenging and reclamation ...

STM also developed a new stirred mill for coarse grinding applications up to 6-mm feed size. The Vertical Power Mill (VPM) line ranges in size from 700 to 12,500 kW with high flow rates and potential energy savings of up to 40%. Due to its small footprint, STM is promoting the VPM as a viable ball mill replacement in HPGR circuits or for ...

This unique one-step process permits a stirred ball mill plant to be successfully and automatically operated in a fully continuous mode. Fig. 4 depicts the principle of the Direct Perl Mill. The system is available with a vertically oriented grinding chamber or, as shown, with an horizontal arrangement.

Ouotec has added complete stirred mill plants to its range of concentrator plants, including patented features like hydrocyclones, samplers, …

Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful application of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning
