COATING METHOD AND APPARATUS

摘要

Coating method and apparatus, in which jet streams of a high-pressure fluid (4, 6) are ejected in the opposed directions into a pulverization zone (13) in a pulverizer to hit a raw material conveyed by one of the jet streams on the other and thereby pulverize the same, the surfaces of particles of the resultant raw material are coated at the same time that the pulverization is done. The raw material to be pulverized is fed into the pulverization zone with a jet stream or by a mechanical means to be then accelerated by a jet stream therein. A coating material is fed in the same direction in which a jet stream flows, or directly into the pulverization zone.
