The non-fluidized stirred mills consist of Tower mill, Vertimill, Sala agitated mill (SAM), and ANI-Metprotech (SVM). These mills are characterized by their low-speed and the use of fairly coarse grinding media size, 3 – 20 mm. Hence, they are mostly suitable for relatively coarse grinding application.

Grinding in these units is completely by abrasion, producing ultrafine particles. MIM's first experience with the tower mill was in the Hilton concentrator in the low-grade middling (LGM) circuit, which is fed from both the lead and zinc flotation circuits. This feed is ground in closed-circuit in the tower mill to 80% minus-25-micron.
The Tower and Vertimill are low speed vertical stirred grinding mills, which commonly use steel balls as the grinding media (Figure 1). The Tower mill was developed in …
