  • Assessing the stirred mill design space ScienceDirect

    The goal of this paper was to propose and apply a simplified stirred mill model that could then be used to assess the stirred mill design space. To this end, a stirred mill model was proposed based on the assumption that the main if not only mechanism of ore breakage is through shear. The basis of this model is the fluid mechanics definition of

  • Investigating the Grinding Media Behavior in Dry-Stirred

    Dry-operated stirred mills hold promise for energy-efficient dry fine-grinding operations. However, the motion of the grinding bead within this mill type is still not well understood. So, the Institute for Particle Technology (iPAT) at Technische Universität Braunschweig recently used Rocky DEM simulation tools to investigate bead contact

    Abstract Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. In the context of the mining industry, interest in stirred milling technologies has grown over the last 20 years where the typical observation reported in the literatu...

  • IsaMill Wikipedia

    The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
