· The nonfluidized stirred mills consist of Tower mill, Vertimill, Sala agitated mill (SAM), and ANIMetprotech (SVM). These mills are characterized by their lowspeed and the use of fairly coarse grinding media size, 3 – 20 mm. Hence, they are mostly suitable for relatively coarse grinding appliion.
said vertical mills have been proven to grind more efficiently than ball mills with feeds as coarse as 6 mm to products finer than 20 microns, and it has become the industry standard in concentrate regrind appliions—but to date vertical mills have achieved only limited acceptance for largescale, coarser appliions.
In fact, in the same appliion a Vertimill® has 50% less footprint than a ball mill. Lower operating cost. Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency ...

· The VERTIMILL® (VTM) is a low intensity stirred mill with a tip speed of 3 m/s. These have been installed in a wide range of secondary, tertiary and regrinding duties receiving feed from AG, SAG and ball mills. More than 400 VertiMill® have been installed globally with total installed power of 227 MW.
The standard Bond Mill test applies for coarser ball milling, but is not appropriate for stirred milling with fine media grinding to 70 microns. With no industry standard test, the energy requirement is often made on the basis of supplier estimates or benchmarking against similar appliions.
(F80) was coarser than 500 µm. Vertical Stirred Milling When evaluating coarse grinding in laboratory scale using the Bond Ball Work Index procedure, small balls (11 mm) in a stirred mill was as efficient as ball milling (Jankovic, A. Cervellin, A., 2004). In fine grinding, testwork in a Vertimill pilot mill showed the better efficiency of
