A material (e.g., proppant) handling system includes a storage container, a mechanical conveyor system, and a pneumatic conveyor system. The mechanical conveyor system is configured to convey material from an unloading station to a conveyor system discharge and into an inlet of the storage container (e.g., at an elevation that is higher than the unloading station). The pneumatic delivery system is configured to deliver material from the storage container to an off-system destination (e.g., a silo or the like), pneumatically. In a typical implementation, the storage container, the mechanical conveyor system, and the pneumatic conveyor system are all on, or connected to, or supported by one common chassis.

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.

A collapsible storage system for flowable material, for example granular material, includes a base frame and an upper frame which is movable between a collapsed position and a working position spaced above the collapsed position. A plurality of storage silos are supported in a row, each including a hopper discharge cone on the base frame and a collapsible tubular wall assembly connected between the discharge cone and the upper frame. Redundant loading conveyors are provided in communication with the silos across the upper frame for loading and redundant unloading conveyors are provided in communication with the silos across the base frame.

A haulage arrangement has a frame configured for operative attachment to a suitable tractor, and defining a tray for operatively receiving particulate material therein. The tray comprises two side walls separated by a loadbearing lower section with a headwall at a head end of the tray and slidably arranged in-between the side walls. Also included is an urger at the head end configured to operatively urge the headwall to slide across the lower section. Arrangement further includes an elastically flexible floor slidably arranged on the lower section and fast at a first end with the headwall, as well as a retractor arranged at an ejection end of the tray and configured to continuously retract a second end of the floor underneath the lower section whilst the headwall is urged. The retractor is further configured to agitate the floor during retraction to counteract adhesion of particulate material ejected from the tray.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.
