The present disclosure is directed to an agitating system having a sub-hopper configured to receive particulate material, an agitator disposed within the sub-hopper and configured to promote movement of the particulate material through the sub-hopper, and a deflector configured to block a portion of the particulate material from exerting a force onto the agitator as the particulate material flows through the sub-hopper. The deflector is positioned such that the agitator extends beyond a first distal edge and a second distal edge of the deflector along a lateral axis.

A particulate material sensing and agitation control system of an agricultural system includes a drive system configured to operate an agitating system, a plurality of sensors, in which each sensor of the plurality of sensors may detect presence of particulate material at the sensor, and a controller. The controller is configured to determine a functional status of each sensor of the plurality of sensors, and, in response to determining the functional status of a respective sensor of the plurality of sensor is functioning, determine a detection status of the respective sensor. The controller is further configured to output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on a position within the agricultural system, the functional status, and the detection status of each sensor of the plurality of sensors.

Embodiments of the present invention include systems for storing large quantities of chemicals at a remote site. A controlled blending system balances the inflow of dry material and liquids into the blender based on a predetermined solid/fluid ratio. The blending system further balances the inflow and outflow of material from the blender.

Dust produced by handling proppant during fracking or other mechanical operations can be a health and/or safety hazard. The dust can be eliminated or at least mitigated using a method of conducting a hydraulic fracturing or other mechanical operation on an oil or gas well including treating a proppant that has been transported to an end use site at a level sufficient to prevent the formation of dust during handling of the proppant.

A system for blending polymers and other chemicals in an aqueous liquid is provided. Static mixers and tubes, preferably in one or more tube bundles, provide a volume sufficient to allow a residence time in the system to hydrate a polymer. Static mixers may be integrated with a tube bundle. The system may be mounted on a portable base such as a trailer. The concentration of polymer and chemicals in water may be controlled by a controller. A variable speed electric pump may be utilized to precisely control the amount of polymers or other chemicals added to the aqueous liquid.

A mobile chemical mixing plant includes an inlet for receiving fluid; a fluid conduit for conveying the fluid from the inlet; a container for containing a chemical therein; a chemical pump for withdrawing the chemical from the container and directing the chemical into the fluid conduit for mixing with the fluid in the fluid conduit to form a chemical mixture; and a homogenization pump for pumping the chemical mixture in the fluid conduit out of the mobile chemical mixing plant. The fluid conduit connects the chemical pump to the homogenization pump. The mobile chemical mixing plant is fixed to a trailer that is attachable to a vehicle. Because the fluid conduit directly connects the chemical pump to the homogenization pump, the mobile chemical mixing plant does not need an intervening mixing tank for mixing the fluid and the chemical.

A single-pass flow-through dry chemical mixing trailer for use with a well has a trailer, a refillable liquid storage tank, a main liquid storage tank valve, a liquid storage tank inlet valve, an onboard power supply, a motor with a fuel supply, a transmission, a fluid circulation loop, a self-priming bidirectional flow alternating centrifuge pump, an automated mixer assembly, and a discharge tank. The refillable liquid storage tank prevents backflow to the self-priming bidirectional flow alternating centrifuge pump while flowing the homogenized slurry to the well and the dry chemicals introduced at the automated mixer are subjected to high shear forces, incorporating the dry chemicals into the liquid with increased dispersion and reduced agglomeration.

A compost turning apparatus may include a towable mobile base being elongated in a longitudinal direction and having a lateral direction. The mobile base may comprise a frame, a tongue mounted on the frame, one or more transport wheels mountable in a transport setup and an operational setup, one or more support wheels mounted on the frame, and a drive wheel mounted on the frame. The apparatus may also include a rotor mounted on the mobile base to rotate about an axis oriented substantially parallel to the longitudinal direction of the mobile base. The rotor may have a plurality of paddles arranged in circumferential rows, with various paddle positions and paddle orientations.

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.
