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.

A continuous mixer that is installed in the bed of a dump truck. The mixer has a hopper for cement, a pair of belts to move the other mixing materials, and a chute with an auger for mixing the cement and mixing materials with water and depositing the mixture where desired. The hopper stands upright in the bed when the bed is down and tilted at about 45° when the bed is up. An auger at the bottom of the hopper feeds cement to an opening at the bottom of the hopper, The belts sit below the hopper and are oriented with the belts parallel to the ground during operation, The belts feed mixing materials from the bed to a mixing chute below the belts. An auger combines the dry materials and water to form the concrete as they travel the length of the chute to the discharge end.

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.

Embodiments relate to a hydraulic fracturing system that includes a blender unit. The system includes an auger and hopper assembly to receive proppant from a proppant source and feed the proppant to the blender unit for mixing with a fluid. A first power source is used to power the blender unit in order to mix the proppant with the fluid and prepare a fracturing slurry. A second power source independently powers the auger and hopper assembly in order to align the hopper of the auger and hopper assembly with a proppant feed from the proppant source. Thus, the auger and hopper assembly can be stowed or deployed without use of the first power source, which is the main power supply to the blender unit.
