Document Type and Number:
WIPO Patent Application WO/2001/091906
Kind Code:
A1
Abstract:
A method of producing ground resin particles, wherein a fluidized bed opposed type jet mill is improved to greatly increase grinding efficiency and operating conditions are alleviated to reduce the device size and running costs. With the use of either a jet mill comprising a plurality of jet nozzles (6) disposed at predetermined positions in the barrel (4) of a grinding chamber (1) and aimed at an injection point (5) in the grinding chamber, and a bottom wall (3), in part or in whole, having a flat surface parallel to the jet nozzles, or a jet mill comprising a plurality of jet nozzles disposed at predetermined positions in the barrel of a grinding chamber and aimed at an injection point in the grinding chamber, and a bottom wall formed with a conical projection immediately below the injection point, resin particles to be ground are spouted, with or without water, toward the injection point by the jet nozzles and thereby ground, the ground resin particles having intended particle size being collected.
