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.

A plant for conveying material for the production of structural concrete comprises a first container configured to contain a first amount of material, a first detection member configured to detect a variation in the first amount of material and first release members configured to enable and/or disable release of the first amount of material towards a mixing area of the first amount of material. The plant further comprises a second container configured to contain a second amount of material varying between a second minimum and a second maximum reference amount, a second detection member configured to detect a variation in the second amount of material and second release members configured to enable and/or disable release of the second amount of material towards a mixing area. In particular, an unloading opening of the second container is connected to the mixing area, whereas an unloading opening of the first container is connected to a loading opening of the second container or to a mixing area. A control unit is configured at least to enable said release members to release the first amount of material when the second detection member detects the reaching of the second minimum reference amount in the second container. The present invention also relates to a process for conveying material for the production of structural concrete.

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 method of operating a concrete batching plant includes loading aggregates into an aggregate storage bin divided into compartments from the ground level by wheel loader, discharging the material from storage bin through batching gates fitted into a weighing hopper, hydraulically lifting the aggregates after being weighed in the weighing hopper, conveying cement through a screw conveyor into a cement weigher and discharging the same into a mixer, mixing and compacting the aggregates for a pre-determined time, discharging the mixed and compacted concrete into a concrete carrying hopper, transporting the concrete carrying hopper to a desired height, and loading the concrete into mobile transit mixer or concrete pump, based on the site requirement.

A method of lining a pipe with a lining mixture formed from a dry component and a liquid is discussed. The method includes placing the dry component in a dry component surface container located above ground, conveying the dry component from the dry component surface container to a dry component subterranean supply container located underground, conveying the dry component from the dry component subterranean supply container to a mixer located underground, mixing the dry component with the liquid to form the lining mixture, and applying the lining mixture to the pipe with a mixture applicator.
