ABSTRACT:
This invention is concerned with a method for forming spherical particles of thermoplastic material, characterized by the step of blowing a stream of gas having thermoplastic particles dispersed therein from a peripheral region into a jet of pressurized hot gas to form the thermoplastic particles into uniform spherical particles. It also provides apparatus for carrying out the foregoing method which includes means for discharging a jet of pressurized hot gas from an outlet port and means for ejecting a stream of gas having thermoplastic particles dispersed therein from the periphery of the outlet port toward the jet of pressurized hot gas.
