An additive feeder assembly includes a supply reservoir having an outlet and an outlet tube having a first end in fluid communication with the outlet and a second end located vertically higher than the supply reservoir. An air stream transports a first granular material discharged from the supply reservoir and into the first end of the outlet tube to the second end of the outlet tube. A granular material distributor is in fluid communication with the second end of the outlet tube. The granular material distributor has a top end configured for attachment to a feed supply for a second granular material, a central portion located vertically below the top end and configured to mix the first granular material and the second granular material, and a bottom end configured for vertically discharging the mixed first granular material and second granular material.

A weigh hopper assembly including a plurality of adjacently aligned weigh hoppers connected via a frame, and longitudinal conveyor mechanism extending along a top portion of the weigh hopper assembly. Each weigh hopper has independent load cells in order to individually weigh the material discharged into the weigh hopper. The conveyor mechanism includes a plurality of gates along a bottom surface of the conveyor mechanism, each gate being aligned with a corresponding weigh hopper of the plurality of weigh hoppers. The conveyor mechanism is in turn connected to a plurality of product bins. A top portion of the conveyor mechanism is in communication with a plurality of product bins via a series of inlet chutes and gates. The weigh hoppers are aligned adjacent to each other and spaced so that each weigh hopper aligns with the transport vehicle.

A method and means to manage timing and delivery of paving material to refill a paver during a paving operation is provided. The invention employs a semi-automated dump routine to manage the level and condition of material in the dump hopper of the material transfer vehicle (MTV) thereby minimizing flaws in the roadbed otherwise expected. Further, the invention provides for monitoring and managing multiple operational data pertaining to delivery of material related to the paving process to determine and coordinate timing of travel and delivery of the paving material to increase optimal conditions of the paving material to minimize road and pavement defects.

A proppant metering and loading apparatus for a hydraulic fracturing blender unit is provided. A continuous loop conveyor belt receives proppant from a source location on the blender, such as a hopper, and delivers the proppant to a blender device of the blender. A measurement device (e.g. weigh scale) measures and provides an indication of amount (e.g. weight, volume and/or density) of the proppant delivered to the blender device by the conveyor belt.
