Abstract (en)
[origin: EP3401250A1] A system for conveying proppant includes a conveyor assembly to receive and support one or more containers having proppant stored therein, having a conveyor belt that receives proppant from the one or more containers. The system also includes a conveyor auxiliary unit connected to an end of the conveyor assembly having one or more joints to enable expansion and collapse of the conveyor belt from the conveyor assembly. The system further includes a movable proppant chute to direct the proppant from the conveyor belt into a blending hopper, and a tub positioned at an inlet of the blending hopper, the tub being removable from the blending hopper and positioned at a lower elevation than the proppant chute when coupled with the blending hopper.
