A vertical hydraulic tank includes an upper cylindrical section and a lower conical section, with an outlet in the lower conical section. A lower multi-path manifold is attached to the outlet, the manifold including a vertical conduit in fluid communication with the outlet and a plurality of horizontal conduits in fluid communication with the vertical conduit. An upper multi-path manifold can also be attached to the tank with a plurality of upper horizontal conduits and a vertical conduit in fluid communication with the upper cylindrical section of the tank. Valves may be provided along the vertical conduit and the horizontal conduits to regulate flow of material through the conduits. A pump may be connected to either the upper manifold or the lower manifold, or both by way of a pump conduit. Multiple tanks can be connected together by way of tubing between the manifolds of each tank.

A mobile proppant delivery system may include a system for unloading proppant transport trailers, storing proppant in silos, and feeding proppant to frac operations. The system may include drive-over conveyors, swiveling distribution heads, internal silo bucket elevators, gravity feed, choke filling, and bases designed with internal conveying systems.

In an article processing apparatus (1), a plurality of hoppers (12) are disposed in a circular shape and each of the plurality of hoppers (12) causes an article (100) received from an upstream side to temporarily stay and then discharges the article (100) toward a discharge opening (20) on a downstream side. Each of the hoppers (12) includes: a body portion (12A); a slide portion (12B) provided on a downstream side of the body portion (12A), and having a slide surface (120) extending continuously from the body portion (12A); and a gate (12C) provided on the body portion (12A) to switch between a first state where the gate (12C) causes the article (100) to stay in the body portion (12A) and a second state where the gate (12C) releases the staying of the article (100) to cause the article (100) to slide down from the body portion (12A). The slide portion (12B) has a length (L) or an angle (A) with respect to a horizontal direction (H) of a path along which the article (100) slides down the slide surface (120), takes off from a downstream end portion (120E) of the slide portion (12B), freely falls in a space (S) where the slide surface (120) does not exist, and then reaches the discharge opening (20), in the second state.

An articulation mechanism for large scale mobile aggregate system equipment. The mechanism includes a screw device that is pivotally secured to an elongated portion of the equipment to drive its movement to and from a collapsed position. The screw device is driven by a screw jack and moved within a housing while the housing itself is pivotally secured to another portion of the equipment. Rollers within the housing may be used to stabilize the lateral movement of the screw device during the opening, closing or self-locking of the elongated portion by the mechanism.
