Aggregate washing systems are described including mechanisms for slurrying, washing and/or dewatering aggregate material.

A storage and mixing device for two-component polymethyl methacrylate bone cements having a cylindrical interior of a cartridge that is delimited on a front side by a cartridge head, a plunger arranged to be axially movable in the cylindrical interior of the cartridge and spaced from the cartridge head, a powdery first parent component of the bone cement, that is contained in the interior between the plunger and the cartridge head, a feed-through arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head. The feed-through is connectable to a fluid line, a receptacle for a monomer liquid, wherein the fluid line connects the feed-through to the receptacle in a liquid-permeable manner, and a press-out device pushable into the receptacle, so that monomer liquid is pressable out of the receptacle into the fluid line. The plunger (2) is spaced from a back side of the cylindrical interior, located opposite the front side, so that, by moving the plunger in the direction of the back side, the press-out device is pushable into the receptacle and a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head.

A storage and mixing device for PMMA bone cements having a cylindrical interior of the cartridge that is delimited on a front side by a cartridge head with a closed delivery opening, a plunger which is arranged to be axially movable in the cylindrical interior of the cartridge and which is spaced from the cartridge head. The plunger circumferentially rests against the inner wall of the interior, so that the plunger divides the interior of the cartridge into two sections in a gas-tight manner, a powdery first parent component of the bone cement, which is contained in the interior between the plunger and the cartridge head, a feed-through which is arranged in the cartridge head or in the cylinder barrel of the cartridge between the plunger and the cartridge head, wherein the feed-through is connected to a fluid line in which a monomer liquid as a second parent component of the bone cement is contained or into which a monomer liquid is fillable or introducible. A filter is arrangeable in the cartridge head, in the feed-through and/or in the fluid line, wherein the filter is permeable to the monomer liquid and impermeable to the first parent component, wherein the plunger is spaced from a back side of the cylindrical interior, located opposite the front side, to an extent that, by moving the plunger in the direction of the back side, a reduced pressure is producible in the interior of the cartridge between the plunger and the cartridge head, wherein the reduced pressure is able to suck the monomer liquid out of the fluid line into the interior of the cartridge.

A continuous extrusion kneader comprising a first supply section for supplying a solid electrolyte, a first kneading section for kneading a material supplied from the first supply section to provide an intermediate mixture, a second supply section for supplying an electrode active material to the intermediate mixture, and a second kneading section for kneading the intermediate mixture and the material supplied from the second supply section, wherein the first kneading section comprises a forward kneading section for kneading the material supplied from the first supply section and conveying the material downstream, and a reverse kneading section for kneading the material supplied from the forward kneading section and applying a force in the upstream direction.

An apparatus for mixing and pumping, the apparatus comprising a housing with an inlet and an outlet for receiving and expelling liquid and a material. The apparatus has a shear rotor and a stator for mixing the liquid and material and an impeller for pumping the liquid and material from the inlet, via an annular clearance between the shear rotor and the stator and to the outlet. The apparatus has a return conduit configured to return to the inlet a part of the liquid and material pumped via the annular clearance and openings in the stator.

An apparatus configured to process foodstuff materials can include an exterior tube, an inner shaft, and multiple differently shaped protrusions. The exterior tube can have a foodstuff inlet, an outlet, and a longitudinal axis, and can be configured to facilitate the conveyance of foodstuff materials along a material passage from the foodstuff inlet to the outlet. The inner shaft can be located within the exterior tube, can extend along the longitudinal axis, and can combine with the exterior tube to define the material passage. The inner shaft can be configured to be rotationally driven. The multiple differently shaped protrusions can be coupled to and extend from the inner shaft, and these differently shaped protrusions can be configured to process the foodstuff materials when the inner shaft is rotationally driven. Processing can include conveying, agitating, and/or hydrating the foodstuff materials.
