The technical features of the stirred media mill were described earlier by CELEP et al 8. Energy consumptions in the grinding tests were measured using an electrical counter connected to the stirrer rotor.

  • Vxp2500 Stirred Mill Optimization At Casmyn Mining

    The 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 disc.

  • Effect Of Agitator Shaft Direction On Grinding Performance

    First we proved by milling experiments that the media stirring mill with the horizontal direction of the agitator shaft can provide better grinding performances. Then we further elucidated this experimental evidence by applying DEM simulations to a media stirring milling process in a vertical and a horizontal stirred mill.
