- 摘要：
- A method and apparatus for densifying a thermoplastic polymer are disclosed. Particles of a thermoplastic polymer are introduced into a chamber, suspended with a fluid flow in the chamber, and while suspended, the particles are heated and softened to form pieces of densified thermoplastic polymer which are too dense to remain suspended in the fluid flow. The pieces of densified polymer are collected from the bottom of the chamber. A range of particle sizes can be efficiently and continuously densified without adjusting the apparatus.
