The effect of dry grinding on the structure of talc

A porcelain mill of 930 cm3 and porcelain balls 3 cm in diameter were used. An amount of 310 cm3 of talc was used and the rotation rate was 78 rpm. In the ball mill 27 hours were necessary to obtain talc with properties similar to the ones obtained after 5 minutes of grinding in the oscillating mill.The grinding depended study of properties of ball clay is not understood and the above facts invite an attention to undertake a study on the structural, dielectric and morphological properties of ball clay with wet grinding. The wet grinding treatment was performed using ball and vibro mills for different time spells of 2, 4, 8 and 16 hours (h).Structural, dielectric and surface morphological properties of

The effects of vibratory grinding and calcination on the structure and reactivity of Kalabsha kaolinite were studied by means of XRD, IR, DTA and surface area determination. Leaching experiments on ground and calcined samples were carried out using 20% HCl for aluminum extraction. At the early stages of grinding, partial The well-ordered kaolinite K1 showed slightly higher thermal mass loss (12.6%) than poorly ordered kaolinite K2 (11.4%). On grinding the well-ordered kaolinite the dehydroxylation temperature decreased more intensively (from 562 °C in K1 to 555 °C in K1b and K1j) than in the poorly ordered kaolinite (from 553 °C in K2 to 552 °C in K2b andEffects of brief milling and acid treatment on two ordered
