Grinding caused particles to fragment and resulted in the formation of stable large spheroidal aggregates of fine particles. These two processes were not clearly separated by a specific grinding time, but occurred in parallel shortly after grinding was started, although aggregate formation persisted at longer grinding times.

After drying, the kaolin is pulverized in a roller mill and is fed into the grind- ing section of the mill where plows lift the clay into the area where the rollers grind it against the grinding ring. The disintegrated kaolin may then be air classified whereby the finely ground product is lifted through the top of the machine to the outlet duct.
