Stirred media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products SMD’s feed size is typically 80% passing 100 µm and finer, but it can also handle coarser materials in various applications Gravityinduced Stirred Mill – In these mills, media motion is driven by the rotation of a helical impeller; the speed is not sufficient to fully suspend the media, and so at the top of the helix, the media cascades downwards under gravity; this settling ensures that the media remains in intimate contact for efficient grinding, and leads to a Stirred media mills in the mining industry: Material The HIGmill® is a high intensity stirredmedia grinding mill for fine and ultrafine grinding Initially designed for use in the industrial minerals sector, the HIGmill® has recently been used in metalliferous projects around the world The HIGmill® can be advantageous HIGmill® Grinding Solutions Ltd
Investigating the effect on power draw and grinding
The design and operating parameters of a stirred media mill have an effect on the efficiency of the grinding process occurring in the mill There are many factors that can influence efficiency Some of the main factors are the physical mill design, the choice of grinding media size and density, the speed of the stirrer, and the slurry density 1 Introduction Nanoparticles production using stirred media mill is very efficient technique for the large scale production of nanoparticles Nanoparticles can be produced by the topdown or bottomup methods in solid, liquid and gas phase Amongst different available routes, production of nanoparticles using the top down approach by a wet grinding process is a very promising techniqueEnhancement of stirred media mill performance by a Figure 101 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessensStirred Mills – Ultrafine Grinding ScienceDirect
