  • Vertical stirred mill scaleup and simulation: Model

    Vertical stirred mills are typically loaded with smaller media, and part of this extra efficiency would be due to the increased specific surface of the smaller media and, consequently, an increase in the grinding action, especially for smaller particles (Mazzinghy et al, 2015a)ConwayBaker et al [] studied the effect of the impeller design on the media motion inside a vertical stirred mill by using Positron Emission Particle Tracking (PEPT)Three impellers were tested: a flat blade, a pin type and down pitched impeller This work highlighted how the impeller strongly influences the upper and lower recirculation loops inside the mill, andInvestigating grinding media dynamics inside a verticalA series of stirred mill experiments were performed with two types of agitator designs a standard pin type and CSIRO’s designed double helical screw stirrers The effects of operating parameters such as grinding time, stirrer speed, and pulp density on grinding performance was investigated using a magnetite concentrateA Comparative Study on a Vertical Stirred Mill Agitator

    Stirred mill technology dates back to 1928 where the idea to use “an agitator and spherical grinding media” was presented The year 1948 saw the successful application of DuPont’s “sand mill” for pigment grinding Subsequent years have led to the development of different types of stirred mills spanningper cent before grinding performance suffers, and this is particularly useful in times when for whatever reason nameplate capacity cannot be maintained Operating principle – fluidizedmedia stirred mills In contrast to the gravityinduced stirred mills, the fluidized mill type uses high rotationalTECHNOLOGY SELECTION OF STIRRED MILLS FORThe effect of disc diameter on grinding performance was examined by selecting three different disc sizes The standard grinding disc diameter in the VXP2500 is 950mm This research program also used 920mm and 890mm discs to determine the effect of adjusting the gap between the wall of the mill and the tip of the grinding discVXP2500 Stirred Mill Optimization at Casmyn Mining
