Effect of dry grinding on chemically modified kaolin
The effect of dry grinding on the morphology and structure of kaolin particles treated with potassium acetate (KAc) and dimethyl sulfoxide (DMSO) has been investigated. After treatment with KAc, the d-spacing of kaolin increased from 0.72 to 1.03, 1.30, and 1.38 nm due to the combined effects of humidity and orientation of KAc molecules.

Detrimental effect of calcium on grinding performance of a kaolin
The grinding performance was reduced by the addition of Ca 2+ ions when there was a high clay percentage (40%) and a high solid percentage (70%). This paper demonstrated the importance of controlling Ca 2+ concentrations in plant water to maximize the grinding performance of kaolin-containing ores.This work aims to assess the potential reactivity of a mechanically activated kaolin for its use as an alternative cement precursor. The mechanical activation was successfully achieved by grinding at different rotation speeds (250, 300, and 350 rpm) and times (60, 90, and 120 min), obtaining a highly amorphous and reactive material.Potential reactivity assessment of mechanically activated kaolin

Detrimental effect of calcium on grinding performance of a kaolin
The presence of kaolin in ores may cause many problems in mineral processing industries. However, no study was conducted investigating the influence of kaolin on grinding efficiencies in any clay-containing ores. The primary objective of this research is to investigate the influence of kaolin on the grinding efficiency in the absence and the The results show that the combined application of ball grinding (at 400 rpm) and AlCl 3 (0.5 wt%) could give the highest bleaching efficiency, wherein the Fe 2 O 3 content decreased from 1.34% to 0.76% for Beihai kaolin, and 2.05% to 1.42% for Xingzi kaolin, corresponding to an increase of 4.98 and 12.12 percentage points, respectively.
