Effects of filling degree and viscosity of slurry on mill

Using a transparent mill of internal diameter 552 mm and length 180 mm, the load behaviour of a 10 mm ball charge filled at 20% of the volume of the mill and run at 60% critical speed was videoed.

Measurement and evaluation of the grinding bodies’

An increasing viscosity shows initially no visible influence on the grinding bodies’ centre velocities. In the case high viscosities are reached, a significant decrease in the grinding bodies’ velocities appears due to the higher flow resistance or more specifically, higher fluid’s resistance or lower fluid’s flowability counteracting the motions.

Measurement and evaluation of the grinding bodies’

2020-10-1  The influence of the fluid viscosity and the fluid’s filling quantity or level inside the mill chamber on the grinding bodies’ motions has been studied using different GWMs. Initially, an increasing viscosity has no significant effect on the grinding bodies’ centre velocities, which remain constant within a wide range of viscosities.

Experimental assessment of grinding bead velocity

Viscosity influences grinding by axial grinding media distribution. The tip speed especially influences the highest bead velocities. Abstract. Fine grinding in stirred media mills is an important process in mineral, chemical and pharmaceutical industry. The stressing mechanism in these mills is grinding through compression and shearing by grinding
