Stirred Media Detritor,SMD or Sand Grinder for Sale

This mill utilizes a vertical shaft pin agitator. Media is typically high-grade alluvial silica sand or ceramic spheres in the range of 1 to 3 mm in diameter. The agitator speed is high enough to fluidize the media. Screens fitted to the upper circumference of the mill body allow product to leave the mill while retaining the media. These screens do not act as a classifier but function only to retain the media. Feed size is typically in the range of 100 Pm down to 15 Pm, and products as fine as 98% passing 2 Pm are achievable. Typical applications in the metalliferous industry have products down to 80% passing 6 Pm.

The stirred milling technologies currently available can be divided into two sub-categories: gravity-induced and fluidized. Gravity-induced stirred mills initiate a ball charge motion via rotational movement of a screw to provide a size reduction mechanism. In contrast, fluidized stirred mills use a rotational movement to fluidize a media-slurry mixture, resulting in a size reduction mechanism. The type of mill and the circuit configuration are intrinsic to maximizing the grade and recovery profile of an ore. Formats has both stirred milling technologies in the Vertimill and the Stirred Media Detritor (SMD), allowing Formats to offer the optimum equipment solution for the circuit.
