Parameter effects on wet ultrafine grinding of CORE

Wet ultra-fine grinding of a limestone powder (< 100 μm) has been investigated in a stirred media mill with respect to the effect of slurry rheology. The grinding results obtained by various parameters (i.e., molecular weight of a dispersant, solids concentration, additive dosage, addition method and beads load) are evaluated in terms of

effect of slurry rheology and flow rate on mill behaviour. He had already highlighted the interaction between slurry and media in the mill by looking at the mill grinding efficiency. At that time, it was difficult to acquire a lot of valuable information as robustness in an aggressive environment was not assured.

It is therefore used as a grinding aid for the wet ultrafine grinding of limestone. The rheological behaviors of ground limestone slurries vary with grinding from a starting dilatant flow-ability to a resulting pseudoplastic one with an evident Casson yield stress in combination with a thixotropic character.

Analysis of Variables Governing the Operation of a

The effect of slurry rheology on mill performance was shown by assessing the effects of increasing solids concentration and decreasing particle size. Rheological effects seemed to interact with mill speed such that the mill was less energy-efficient at higher solids content and at higher mill speeds particularly for grinding to fine particle sizes.
