Abstract: This invention provides a mixing chamber that utilizes several tined cylinders to convey materials through the mixing chamber for applying liquid additives to the materials. Each of the tined cylinders includes a number of spring biased tines extending from the surface of the cylinder. The tined cylinders are arranged within the mixing chamber such that, as the tined cylinders rotate about an axis, the spring biased tines engage the materials within the mixing chamber and “sweep” them along towards a discharge opening of the mixing chamber. As the materials are conveyed through the mixing chamber, an additive liquid, typically containing various chemicals, colorants, dies, and/or paints, is sprayed onto the materials. In this manner, liquid additives are applied to materials more evenly and more thoroughly, resulting in a more consistent finished product.

The conveyor assembly includes a cement metering function as well as a slurry mixing function. A selectively openable and closable bypass gate permits the dry cementitious material to be sent directly to the final product mixing chamber in the event of conveyor failure.

Abstract: An extrusion apparatus having a rotor member rotatable within a barrel member longitudinal and cross-sectionally mixes and extrudes thermo-plastic and thermo-setting materials. The apparatus is articulated into sections including a barrel entrance and forcing section, a blending section, and an end discharge section. The barrel entrance and forcing section consists of helical extrusion grooves which terminate at an abrupt rotor to barrel and barrel to rotor material transfers.

Longitudinal displacement is accomplished in the blending section by providing a double extrusion capacity main extrusion rotor and a single capacity backfeed rotor arranged to recirculate half of the material processed by the main stream rotor.

Abstract: 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.

The use of relatively fast moving beaters within a small mixing chamber in combination with relatively slow moving paddles in a larger mixing chamber enables flour-like materials to be properly blended with water with both sufficient agitation and proper retention times within the vessel.
