Abstract

See full text

A method is provided for applying polymers to coat particulate cores in a rotor processor. The processor is actuated to create a circulating bed of cores in the rotor chamber. Dry powdered glidant is introduced into the rotating bed of cores, which are simultaneously sprayed with a polymer solution. The glidant enhances processability by eliminating or minimizing agglomeration of the cores. Air from above and below the rotating bed evaporates the solution to leave a polymer layer on the cores. Layers of polymer build up on the cores until a desired thickness is achieved.
