Abstract
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.
