DYNAMIC COOLING

摘要

A polymer processing system includes a mixer. The mixer includes at least one side wall and a bottom wall that cooperate to define a chamber. At least one side wall also defines a bore. The mixer also includes a pair of rotors that are disposed in the chamber and are rotatably received by the at least one side wall for mixing polymers. The mixer also includes at least one injector that at least partially extends through the bore of the at least one side wall. The polymer processing system also includes a ram that is movably connected to the mixer. The polymer processing system also includes a compressed air supply that is fluidly connected to the at least one injector to supply compressed air to the chamber through the at least one injector.

1. A polymer processing system, comprising:
a mixer including
at least one side wall and a bottom wall that cooperate to define a chamber, the at least one side wall also defining a bore,a pair of rotors disposed in the chamber and rotatably received by the at least one side wall for mixing polymers, andat least one injector that at least partially extends through the bore of the at least one side wall; a ram movably connected to the mixer, the ram selectively extending into the chamber of the mixer so that the pair of rotors are between the ram and the bottom wall; and a compressed air supply fluidly connected to the at least one injector to supply compressed air to the chamber through the at least one injector, wherein the compressed air supply supplies the compressed air to the at least one injector at a pressure that is greater than a pressure of atmospheric air immediately surrounding an exterior of the mixer.
