Modelling Of The Effect Of Rheology In Ball Mill Grinding

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44- m (−325-mesh) material reached maximum at 70 solids, whereas the ball wear decreased as pulp.

  • Effect Of Water & Density On Grinding Mill

    Mar 17, 2017 As you increase the volume of the through put, the time that the ore has to react to the grinding media is lessened. As you add ore to the mill you are also adding WATER and changing density which affects the slurry rheology and workings of the grinding action inside that mill. This water is one- of the main controls that you have over your grind.
