Amorphization of kaolinite and media motion in

2000-1-1  The UF mill lead to an amorphous state of kaolinite for a shorter time than the tumbling ball mill. The ball impact energy in the UF mill was about 5 times larger than that of the tumbling ball mill. The simulated total kinetic energy of media balls required for 80% amorphization of the sample by the UF mill was considerably lower than that using the tumbling mill.

Influence of dry grinding on talc and kaolinite

2005-8-1  The high power ring mill has affected kaolinite and talc far more than the porcelain ball mill. Prolonged grinding (60 min) of mixtures (10% talc) produces rounded aggregates that are composed of nano-meter sized colloidal particles.

Algerian kaolinite used for mullite formation

2008-2-1  Before milling particles of kaolinite have irregular shapes and large particle size distribution. However, milling for 5 h decreased the particle size, and yielded a homogeneous powder mixture with particles having almost spherical shape which would promote sintering. Fig. 3 shows TG/DTA and DTG/DDTA curves of kaolinite (heating rate of 20 °C/min). Two endothermic peaks at 105 °C and 508
