Delamination of kaolinite–potassium acetate intercalates by ball .Aug 15, 2010 . The X-ray diffraction pattern at room temperature indicated that the intercalation of potassium acetate into kaolinite caused an increase of the basal spacing from 0.718 to 1.42 nm, and with the particle size reduction. The surface area increased sharply with the intercalation and delamination by ball-milling.kaolin delamination bead mill,Effect of Intercalation Agents on Morphology of Exfoliated KaoliniteDec 16, 2017 . 12.

Feb 12, 2017 . Good fluidity (low viscosity) of highly concentrated kaolin is highly needed in paper-coating industry. We put forward an effective route to improve the viscosity concentration of Beihai kaolin.
ground kaolinite in a ball mill for 192 hours and concluded that decomposition to a permutite-like material occurred. They showed that both the effective particle size (as determined by sedimentation) and the B.E.C. increased up to 96 hours, and then decreased, whilst the B.E.C. finally became constant at a value higher.
In the examples presented herein, delamination was carried out by subjecting an aqueous slurry of stacked kaolin particles to shearing action in a sand grinder. It is to be understood, however, that the delamination may be carried out in other devices such as, but not limited to, ball or pebble mills, extruders or rotor-stator.

Comminution of kaolin clay samples, using attrition-milling in a stirred bead mill and high energy kneading in a pug-mill, was investigated at laboratory scale. Attrition-milling was shown to provide predominant delamination within the first minutes, prolonged treatment resulted in more marked transverse breakage of clay.
Being the wearing liner for the ball mill, alumina lining brick is the best choice to increase the grinding efficiency and reduce the grinding cost. . Calcined Kaolin. Kaolin based pigments are produced through delamination, calcination and classification. The well-controlled process ensure have no coarse particles and.

On the downside, D. Yan states that ultrafine grinding techniques are less predictable than conventional ball mills in terms of energy requirement and grinding performance while . Using relatively fine grinding media, the Hicom mill achieved better delamination than a sand mill currently used by a china clay producer.
