Walter Kelley investigated grinding of bentonite and kaolinite, and formulated a theory including only a physical disintegration of the minerals followed by a decrease in the particle size. Alfred Perkins stated, that grinding induces also disorders in the crystal lattice structure, (Gregg et al. 1953 ; Garcia et al. 1991 ).

Kaolinite - an overview | ScienceDirect Topics
Kaolinite-enriched rocks are generally called kaolin or china clay [177]. This clay encloses a white mineral called dioctahedral phyllosilicate that is formed by chemical changes to aluminum silicate minerals including feldspar [178]. For ceramic applications, kaolin is heat treated and altered into Al 2 O 3 .2SiO 2 .2H 2 O.
