Latest Patents
One of Andrew L. Wilcher's notable patents is titled "Method for producing low abrasion kaolin pigment." This patent describes an improvement in the method for producing a calcined kaolin clay powder. The process involves wet beneficiating a kaolin crude, drying the beneficiated crude, milling it to create a calciner feed, and then calcining the feed to eliminate crystallinity, resulting in an amorphous calcined kaolin powder. The improvement focuses on milling and classifying the dried beneficiated crude to ensure minimal residue, which leads to reduced abrasion and viscosity in the final product. This innovation allows for a higher solids slurry, enhancing the overall quality of the kaolin pigment.
