Abstract
Provided is a method for manufacturing thermoplastic polymer particles, the method comprising the steps of: supplying a thermoplastic polymer resin to an extruder and extruding the same; supplying the extruded thermoplastic polymer resin and air to a nozzle, bringing the thermoplastic polymer resin into contact with the air to granulate the thermoplastic polymer resin, and then discharging the granulated thermoplastic polymer resin; and supplying discharged thermoplastic polymer particles to a cooling unit to cool the thermoplastic polymer particles, and then collecting the cooled thermoplastic polymer particles.
