ABSTRACT:
Coated carrier materials are prepared by electrostatically attracting particles of a coating material to the surface of carrier cores and then heating the carrier materials causing the coating material to fuse to the carrier material forming an adherent coating thereon. The coating material is attracted to the carrier materials by (a) rolling carrier materials down an inclined plane while spraying the carrier materials with a coating material; (b) dropping carrier materials through a cloud chamber containing a cloud of coating material particles; and (c) solids blending a mixture of carrier materials and particles of coating material.
