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 steam 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 roller mixer, followed by screening, and subsequent pelletization in a roller while drying. The pellets are dried to 1% or less moisture content by weight based on the weight of dry kaolin clay.
