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.

a certain size and then grinding to a powder. The fineness of the powder depends upon the dispersion of the mineral of interest. Crushing is done mostly using mechanical crushers. Crushed materials produced are usually below 1014 mm ( to inch dia) so as to directly feed into the grinding milling machine.
