Abstract (en)
[origin: US4797080A] A kneading machine with a charging opening leading to a kneading chamber, in which two axially parallel kneading tools can be driven in opposite directions at different rotational speeds, has at least three such kneading chambers which are disposed next to each other and an aperture which connects their internal spaces. The material to be kneaded can be conveyed through this aperture, which extends transversely of the shafts of the kneading tools from one kneading chamber to the next, so that the material is continuously treated until it reaches in the last kneading chamber an evacuating opening and preferably an evacuating worm which is mounted at such location and by means of which the material is ultimately evacuated from the machine. In this manner, the advantages of a kneading machine with shafts for kneading tools which are journalled at both ends are combined with the advantages of continuous treatment of the material to be kneaded. This also renders it possible to vary the shapes of kneading tools in the of kneading chambers.
