Device for plasticizing and homogenizing tough masses

摘要

A device for plasticizing and homogenizing viscous masses, especially plastics and rubber, in which processing of the material takes place between a rotating drum and a stationary semicylindrical trough partially surrounding the drum which, on the inner surface facing the drum, contains several mixing grooves each extending in a generally longitudinal direction along the inner surface of the trough structure and spaced circumferentially from each other. The grooves are interconnected by channels or slots so that they operate in a sequential manner cooperatively with the drum to properly mix the material introduced at the drum surface.
