Mechanochemical effects in kaolinite grinding. II ...
1986-1-1 · More recently, Hlavay et al. (1977), using a vibrating mill, studied the grinding effect on a kaolin by IR. These authors observed a progressive lattice disruption of the mineral structure. In this work, the structural alterations in kaolinite caused by grinding in an oscillating mill are studied by means of XRD and IR absorption spectro- metry.

The Characteristics of Mechanical Grinding on Kaolinite ...
2017-1-16 · 3.1 The effect of grinding time on the kaolinite str ucture It can be found that the peaks of kaolinite in the diffractograms decrease in the strength and become wide in the shape with the increasing grinding time. This indicates that the crystallinity of kaolinite decreases and the kaolinite structure is d estroyed gradually with the grinding.

Prototropy in Kaolinite during Percussive Grinding ...
When kaolinite undergoes percussive grinding, pronounced changes take place in its i.r. absorption spectrum even in the earliest stages of the grinding when the lattice is not yet destroyed. In this report, attention is directed to the change in the stretching bands of the hydroxyl ions. A remarkably rapid effect on the band of the intralayer hydroxyl ions has been observed
