A system for delivering and applying a flowable mixture to an article (311-313) is disclosed. The system includes a mixture delivery system (200) and a skinning system (300). The mixture delivery system (200) includes a mixer (220) configured to mix a dry material and a fluid to produce the flowable mixture, and a pump (235) configured to pump the flowable mixture to a delivery line. The skinning system (300) receives the flowable mixture from the mixture delivery system (200) through the delivery line. The skinning system (300) includes a skinning pipe (310) configured to apply the flowable mixture to the article (311-313) and a manifold (305) that supports the skinning pipe (310). The skinning system (300) also includes an article feeding mechanism (315) configured to push the article (311-313) into the skinning pipe (310). The skinning system (300) includes a transfer system (320) configured to hold the article (311-313) and move the article (311-313) out of the skinning pipe (310).

There is provided apparatus (301) for mixing contents of a receptacle, the apparatus comprising a rotary shaft (302) equipped at a proximal end with a connection for removable attachment to a means of providing rotation. The rotary shaft has a mixing element (303) fixedly connected at a distal end of the shaft opposite to said proximal end. The mixing element comprises at least two arms (304) at the distal most end of the shaft, a corkscrew neck (306) on the shaft and a collar (305) on the shaft positioned in between the at least two arms and the corkscrew neck. The at least two arms are configured in a first partially-open resting position and are moveable to a second fully-open operative position. The mixing element further comprises a blade (307) positioned across the shaft more proximally than the corkscrew neck.

A technique facilitates mixing of cement slurry for use in a cementing application. At least one cement mixer is provided with a tank, e.g. a conical tank, having a powder cement blend inlet and a mixing liquid inlet. A cement slurry discharge may be positioned generally beneath the tank. A mixing assembly also is positioned below the tank and driven by a shaft. The mixing assembly is exposed to an interior of the tank and is used to mix the cement slurry when rotated by the shaft and to direct the cement slurry out through the cement slurry discharge. Additionally, a recirculation system comprises an inlet positioned to receive a portion of the cement slurry mixed in the mixing assembly. The recirculation system also comprises an outlet positioned to direct the portion back into the mixer to enhance mixing effects.

A stirrer (1; 100) for stabilizing liquid binding unfinished products intended to form ceramic items comprising a support shaft (2) individuating a longitudinal rotation axis (Y) and contained into a mixing tank (V) of the liquid binding unfinished product, motorization means (3) operatively connected with the support shaft (2) in order to rotate it around the longitudinal axis (Y), and a main operating blade (4), coupled with the support shaft (2) through interconnection means (5) in such a way as to be contained into the mixing tank (V) in order to interfere with the liquid binding unfinished product and cause its continuous mechanical mixing action inside the mixing tank (V) itself when the support shaft (2) rotates around the longitudinal axis (Y). In this case, the stirrer (1) includes a thermoregulation circuit (6), which extends within the support shaft (2) and within the main operating blade (4) and is connected with an external source for supplying a heat transfer fluid crossing the thermoregulation circuit (6) in such a way as to exchange heat with the liquid binding unfinished product within the mixing tank (V), in order to bring the it to a predefined temperature, while the support shaft (2) and the main operating blade (4) integral with it rotate around the longitudinal axis (Y).

Mixing systems that include a mixer housing and one or more disk assemblies for mixing and processing materials is disclosed. The disks rotate to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. The disks may have a plurality of fingers or lobes which extend from a central portion of the disks.

A method for applying a curable building material, in particular in an additive method, including the steps of: providing at least two separate components of the building material; adding the at least two separate components into a mixing apparatus, in particular into a mixing chamber of the mixing apparatus, by a supply apparatus; mixing the at least two separate components in the mixing apparatus to obtain a curable building material in a set, cured state; supplying the set building material via a conveying line to a printing head, which is movable in at least one spatial direction, using a conveying apparatus; applying the set building material by the movable printing head.
