ABSTRACT:
A process for making densified kaolin clay pellets of high bulk density, good handling and bulk flow properties, and low moisture content is disclosed. The process consists essentially of mixing substantially dry kaolin clay with water to bring the total moisture content of the finely divided kaolin clay to from about 17% to about 26% by weight based on the weight of said dry kaolin clay during mixing in a first pin mixer, followed by micropulverization, and subsequent pelletization by pin mixing. The pellets are dried to 1% or less moisture content by weight based on the weight of dry kaolin clay.
