Abstract: A screw pump for feeding highly viscous material such as mixed concrete and the like. Plural projections engage the helical screw of the screw pumps to facilitating removal of the material such as gravel caught in the screw pump. Further for preventing excessive force from being exerted on the screw because of material caught in the screw pump, a spring is interposed between partitioning plates and hydraulic cylinders or crank mechanisms. Further, to make the position of the holder for the partitioning plate stable, plural rollers are provided above the holders.

Abstract: Apparatus for mixing charges of flowable material has an open-top vessel movable up and down by fluid-operated motors along vertical guides, either with or relative to a cover which can seal the open top and is provided with an inlet for admission of fresh charges. The extent to which the cover is movable along the guides is limited by followers which are provided on the cover and extend into channels of the guides. The cover carries one or more rotary agitating devices with orbiting blades which mix the contents of the vessel while the open top is sealed by the cover. The central portion of the concavo-convex bottom wall of the vessel has an outlet normally sealed by a closure which is pivotable by a fluid-operated motor. The vessel is lowered away from the cover for the purposes of cleaning.

Abstract: Mixing apparatus, typically a tractor powered agricultural trailer for mixing and dispensing animal feedstuffs, has a main body in which a main mixing rotor rotates for agitating and stirring the material which it sweeps round lower part-cylindrical wall structure of the body and a lateral extension along an upper side of the main body having a feed out rotor therein for urging the material to and through a discharge door in said extension. The inboard side of the extension is open to the main part of the body and said wall structure includes a part bounding the bottom of the extension which can be moved angularly between a first position close to the envelope of revolution of the mixing rotor to deflect material from entering the extension during mixing and a second position at which it is remote from said envelope so that material is swept into the extension during discharge.

Abstract: The invention relates to a multi-spindle kneading mixer with at least two axis-parallel agitator shafts engaging into one another, one of which is designed as a disk shaft, into which kneading elements of a kneading shaft engage, wherein these kneading elements scrape the product off from the disk surfaces and press it by means of corresponding diverting surfaces into a kneading gap formed on the one hand by the kneading element and on the other hand by the opposite disk surface, the product being moved axially to and from between the disk surfaces.

Abstract: A dual-spindle blender includes a container having two intersecting lobes forming a figure-eight cross section with a cutter blade assembly disposed centered in each lobe. The bottom of one of the lobes is lower than that of the other lobe so that, when small quantities of material are treated, it preferentially falls into the lower bottom to produce a deeper pool which can be operated on by the associated cutter blade assembly. In one embodiment of the invention, the cutter blade assemblies are at the same height and are spaced with their planes of rotation non-intersecting. In another embodiment of the invention, the cutter blade assemblies are displaced in height, whereby the blades are offset from each other. In this embodiment the offset of the blade heights optionally permits their planes of rotation to intersect without suffering blade strikes.

Abstract: A conditioning device for an extruder includes two juxtaposed, frustocylindrical, intercommunicated chambers, one chamber of which has a greater cross sectional area than the other chamber. A mixing shaft centrally located within the small chamber carries a number of radially extending beaters which rotate at a speed twice that of the rotational speed of paddles mounted on a second mixing shaft located in the large chamber and material introduced into the vessel is passed from side-to-side between the two chambers while being advanced along the length of the vessel. 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.
