An improved method for dry milling calcined kaolin clays involves use of an effective amount of an ammonium polyacrylate dry grinding aid which is applied to a calcined kaolin clay product prior to dry milling. This improves flowability of the product through the mill, resulting in an increase in the grinding efficiency and, therefore, an increase in the production rate of the mill.

The milling speed and time are the main factors that determine whether H 3 PO 4 can be stably loaded on the kaolin. The milling speed and time are too low to load H 3 PO 4 onto kaolin, and too high milling speed and time will destroy the structure of kaolin, resulting in complete immobilization of free H + in H 3 PO 4, which cannot be exchanged.
