A mobile volumetric concrete mixing system includes a suction system that vacuums up trench spoils while a trench is being cut. These trench spoils are then screened on-site for particle size to be reused and mixed with water, cement, and/or other admixtures at an auger mixer to form a backfill mixture. This backfill mixture may then be loaded into a hopper that continuously agitates the mixture so that the mixture does not harden before pouring. The agitating hopper is coupled to a discharge chute of the auger mixer and includes one or more augers disposed at various orientations that the backfill mixture is channeled through. From the agitating hopper, the backfill mixture is channeled to an applicator that moves along the trench and that enables the mixture to be quickly poured into the trench with little clean-up required.

A microorganism curing anti-seepage device based on capsule transmission and control includes a stock bin which includes a mixing bin and an oil storage bin separated from the mixing bin. A feed pipe and an oil injection pipe are provided on the stock bin. A central shaft is rotatably provided within the mixing bin. A stirring component is provided on the central shaft. A delivery pipe is provided at a bottom portion of the mixing bin, an oil conduit is provided at a bottom portion of the oil storage bin, a jet pipe is provided at a junction of the oil conduit and the delivery pipe. Since microbial capsules are decomposed layer by layer, after the microbial capsules reach fissures, the microbial bacteria, the nutrient solution and the curing liquid are released step by step, and then calcium carbonate is induced by microorganisms to achieve solidification and anti-seepage of fissures.

Mixer bucket (1) provided with a hopper (12) having a concave bottom portion (120) provided with an opening (122) arranged between a first and a second continuous portions (124)(126); a funnel-shaped member (30) being carried by the concave portion (120) so as to face the opening (122) and define a gravity discharge for mixture; the funnel-shaped member (30) being carried by the hopper (12) by means of a guide (128) aligned with the given direction (D); actuating means (40) being carried by the hopper (12) to move the funnel-shaped member (30) along the guide (128) between a first position (P1), where it faces the opening (122), and a second position (P2)(P3), lateral with respect to the opening (122) in correspondence of one of the first and second flanks (14)(16).

A mixer for synthetic quartz includes a mixing barrel (1), a power transmission system (2), a mixing system (3), and multiple material receiving receptacles (4). The power transmission system is provided above the mixing tank. The mixing system is provided inside the mixing tank. The power transmission system is used to drive the mixing system to move. An opening is arranged at each of two ends of the material receiving receptacle. The multiple material receiving receptacles (4) are arranged at a top portion of the mixing tank, and end portions of two adjacent material receiving receptacles are spaced apart from each other without contact there between. A resin experiences low flow resistance in the material receiving receptacle, and thus can fall smoothly without accumulating in the material receiving receptacle. Moreover, the material receiving receptacle can be cleaned easily.

A system for applying a building material, including: a first component of the building material, including a first constituent and a second constituent; a second component of the building material; a first mixer for mixing the first constituent and the second constituent; a supply device for supplying the first constituent to the mixer; a movement device for modifying a site of application in a space; and a second mixer for mixing the first component and the second component.

A system for applying a building material, including: a movement device for modifying a site of application in a space; a first component of the building material; a second component of the building material; a mixer for mixing the first component and the second component, the mixer including a drive module with a first coupling element and a mixing chamber module with a second coupling element, the drive module and the mixing chamber module being detachably embodied, and the drive module and the mixing chamber module being actively interconnected in an application state of the system by means of the coupling elements.

A method in which a stream of dry cementitious powder from a dry powder feeder passes through a dry cementitious powder inlet conduit to feed a first feed section of a fiber-slurry mixer. An aqueous medium stream passes through at least one aqueous medium stream conduit to feed a first mixing section the fiber-slurry mixer. A stream of reinforcing fibers passes from a fiber feeder through a reinforcing fibers stream conduit to feed a second mixing section of the fiber-slurry mixer. The stream of dry cementitious powder, aqueous medium stream, and stream of reinforcing fibers combine in the fiber-slurry mixer to make a stream of fiber-cement mixture which discharges through a discharge conduit at a downstream end of the mixer.

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).
