A portable mixer includes a frame, a hopper for receiving therein dry cementitious mix, and a chute rigidly coupled to the hopper that communicates with the hopper via an aperture. The hopper and chute are pivotally coupled to the frame. The portable mixer further includes an auger extending from the hopper into the chute via the aperture, a water supply system configured to apply water to cementitious mix, and a motor coupled to the auger and configured to rotate the auger to mix the dry cementitious mix with the water.

An apparatus for preventing proliferation of dust during mixing of material, including a semi-dome shaped element configured for placement over a top opening of a mixing container, a fastener extending along a bottom circumference of the semi-dome shaped element, such that said fastener is configured to couple to the top brim of the mixing container, and an opening in the semi-dome shaped element, the opening configured to accept a vacuum hose.

A portable mixing apparatus for mixing components is disclosed. The apparatus comprises a container for receiving components to be mixed, a frame for supporting the container in a first orientation for mixing components and a driving assembly couplable with the container for rotating the container. The frame comprises: a first handle for gripping with a first hand of a user, the first handle being disposed above a centre of mass of the portable mixing apparatus, when orientated in the first orientation, the first handle extending forwardly of the apparatus over the container; a second handle for gripping with a second hand of the user while the first hand grips the first handle, the second handle being disposed below the centre of mass of the portable mixing apparatus when orientated in the first orientation, the first and second handle being arranged to enable the user to carry the mixing apparatus and re-orientate the apparatus between the first orientation and a second orientation for emptying the components from the container.

An extruder includes a receptacle for containing material to be extruded. The extruder further includes a dispersion blade positioned within the receptacle and a nozzle secured to the receptacle. The nozzle defines a first opening positioned within an interior of the receptacle, defines a second opening positioned outside of the receptacle and defines a channel which extends from the first opening through the nozzle to the second opening defining a flow path which extends from the first opening, through the channel and to the second opening. The nozzle extends through a wall of the receptacle and into the interior of the receptacle such that the first opening is positioned spaced apart from the wall.

A method for mixing concrete constituents that generally has a step of rotating a drum having a probe mounted inside the drum and immerged in the concrete constituents being mixed inside the drum; a step of receiving a first set of pressure values indicative of pressure exerted on the probe by the concrete constituents, the pressure values of the first set being taken at different circumferential positions of the probe during a single rotation of the drum; a step of determining a deviation of the pressure values of the first set from reference data; and a step of reducing a rotation speed of the drum upon determining that the deviation is lower than a threshold value.

A portable mixer includes a frame, a hopper for receiving therein dry cementitious mix, and a chute rigidly coupled to the hopper that communicates with the hopper via an aperture. The hopper and chute are pivotally coupled to the frame. The portable mixer further includes an auger extending from the hopper into the chute via the aperture, a water supply system configured to apply water to cementitious mix, and a motor coupled to the auger and configured to rotate the auger to mix the dry cementitious mix with the water.

A mobile twin shaft mixer is disclosed herein, as well as methods of using the same. A benefit to the mobile twin shaft mixer can be a compact, lightweight, high capacity twin shaft mixer useful for mixing, proportioning, and transporting construction materials in mobile operations. A benefit to the methods of use of the mobile twin shaft mixer can be the supply of modern construction materials to the delivery location at the point of installation.

The present invention relates to a loading device for loading particulate material, comprising a body with a first opening and a second opening, wherein a gasket is arranged at the first opening. The present invention also relates to a mixing device with a loading device according to the invention and a method of loading particulate material using the loading device according to the invention.

A portable mixer that has a first auger, a second auger, a motor, a material loading location, where material may be loaded into the mixer, and a dispensing conduit. The motor powers both the first auger and second auger. Further, the second auger may rotate in a first rotational direction and a second rotational direction and the second auger substantially prevents material from exiting a dispensing conduit when the second auger rotates in the first rotational direction and the second auger distributes material through the dispensing conduit when the second auger rotates in the second rotational direction.

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.
