ABSTRACT:
The invention provides an apparatus for mixing and/or kneading materials comprising a housing defining a mixing and kneading chamber, a mixing and kneading member located in the interior of the mixing and kneading chamber, means for driving the mixing and kneading member in a rotating and/or oscillating motion, and means for cooling the housing and, thereby, the materials processed in the mixing and kneading chamber.
The means for cooling the housing comprise cooling channels provided in the housing and a cooling medium circulating through the cooling channels. The cooling channels are provided with hollow pipe- or tube-like inserts containing the cooling medium circulating through said cooling channels, and only a part of the outer surface of the pipe- or tube-like inserts is in direct thermal contact with the walls limiting the cooling channels. Alternatively, there is provided an intermediate layer by means of which the outer surface of the pipe- or tube-like inserts is in thermal contact with the walls limiting the cooling channels.
