effects of dry grinding on the structural changes of,dec 20, 2004 grinding produced a strong structural alteration, mainly along the c axis, resulting in disorder and total degradation of the crystal structure of the kaolinite and the formation of an amorphous product. the surface area increased with grinding time, mainly in kga-2 (maximum value 50.27 m 2 /g), a result associated with particle-size reduction.choosing the right grinding system for processing pigments,mar 16, 2020 the s-jet is a jet-milling system, which has the advantages of dry-grinding with superheated steam. it is used for ultra-fine grinding of soft to extremely hard materials in a fluidised bed. by using an air classifier, integrated in the mill, the maximum particle size is limited and it is possible to achieve fineness in the submicron range.
