A mixing apparatus for preparing mortar has a screw conveyor for conveying dry material, such as a mixture of sand and cement, from a storage vessel to a mixing chamber. The mixing chamber has an inlet end, adapted to receive dry material from an outlet end of the screw conveyor, an outlet end for dispensing wet mortar, and a water feed between the inlet and outlet ends for delivering a metered flow or quantity of water into the mixing chamber. A mixing device within the mixing chamber mixes the dry material and water and controls passage of material from the inlet to the outlet end. The outlet end is located above said inlet end so the dry material falls under gravity from the outlet end into the mixing chamber, maintaining separation between the dry material in the screw conveyor and the wet material in the mixing chamber.

Provided is a mixing apparatus. The mixing apparatus comprises a housing defining a primary chamber, an inlet for receiving material into the mixing apparatus, as well as an outlet for discharging material from the mixing apparatus. The housing provides within the primary chamber a plurality of rotating shafts, each rotating shaft having a plurality of flailing fixtures associated therewith.

A preparation apparatus for preparing feed for animals, includes a first storage container for storing a dehydrated feed, a second storage container for storing a liquid such as water, mixing chamber, a mixer for mixing the dehydrated feed and the liquid in order to form a feed ration in paste form, and a consumption container arranged to receive the feed ration, wherein the mixing chamber includes an opening, the mixing chamber is mounted movable relative to the preparation apparatus, so as to move from a first position to a second position.

A toilet apparatus has a waste material receiving bowl with an opening at a top of the waste material receiving bowl. A bag receives and retains waste material and an absorbent media introduced through the opening. An agitation device agitate the absorbent media and the waste material at a lower portion of the bag to cause the absorbent media to at least substantially cover the waste material while the agitation device is not contacting the absorbent media and the waste material.

The disclosed apparatus, systems and methods relate to devices, systems and methods for mixing particulate matter such as salt with moisture. In various implementations, the mixer is transportable. In various implementations the mixer comprises a hopper, at least one auger, and a mixing housing. Various implementations, additionally include at least one liquid tank.

The present invention relates to a dosing device for a product in powder form, comprising a holder (10) intended to hold a first quantity of the product therein. The holder is provided with dosing means to draw off the product from the holder and move it to an outlet. The dosing means comprise a worm body (20) with a worm thread (21). In a first aspect the worm body comprises at an outer end facing toward the outflow opening at least one further worm thread (22) which runs between the first worm thread (21). In a second aspect the worm thread (21) encloses a smaller volume between successive turns at a base than between successive turns in a part thereof located further toward the outer end.

Static plant for preparing feed mixes for ruminant livestock, having a conveyor unit for conveying the feed mix ingredients, chain and/or screw feeders, feeders with weight sensors and supplementary conveyor belt, silos of solid ingredients, and silos of liquid ingredients, independently supplying via the conveyor unit, with dual flow, two or more high-capacity mixers.

A system for electric-motor driven transportation mechanism for fracturing operations is disclosed. The system includes at least one transportation mechanism to transport blender components for a blender fluid from a first tub that may be a proppant hopper to a second tub that may be a blender tub and that may be associated with a fracturing blender; an electric motor and a control unit associated with the at least one transportation mechanism; and at least one variable frequency drive (VFD) associated with the electric motors for real time control of a speed associated with the at least one transportation mechanism.

An installation for storing, metering, and dissolving water-soluble polymer particles, in particular for enhanced oil and/or gas recovery operations, includes a so-called polymer dissolution container A and at least one so-called polymer storage and distribution container B positioned upon container A. The bottom of container B and the roof of container A each have an opening facing one another allowing the passage of the polymer from container B into the supply mechanism of container A. The installation further includes a connection mechanism able to work with the polymer supply mechanism.

A mobile aggregate hopper for a volumetric and gravimetric mixer having arcuate longitudinal walls for holding and isolating aggregate. The mobile aggregate hopper has a base integral with the arcuate longitudinal walls with an aggregate transfer conveyor capable of attachment to a trailer or chassis having wheels. The single sheet structure of the longitudinal arcuate side walls minimizes welding and mechanical joints during manufacturing and provides a hopper with high strength and capacity and low overall weight.
