A wet sand loading system includes a material conveyor configured for carrying wet sand from a hopper to an elevated position over a loading platform. A funnel assembly is coupled to the material conveyor. The funnel assembly has a lower end movable relative to the material conveyor to direct wet sand into the hopper in a selectable direction.

A kit for forming a hopper bottom of a particulate material storage container comprises a generally conical lower section having a tapering diameter from a first end to the second end such that the second end is sized diametrically smaller, and a plurality of arcuate cone segments each defining an inclined concavely curved wall following a generally circular curvature, all of which can collectively form a hopper cone. The arcuate cone segments are connected in an annulus in which the walls of the arcuate cone segments collectively form a generally conical second cone section having a tapering diameter from one end to an opposite end which has a diameter substantially equal to that of the second end of the first cone section. Afterwards, the opposite end of the formed second cone section is connected to the first end of the first cone section so as to form the hopper cone.

A pulverized-fuel supply unit includes a hopper, first nozzles, second nozzles, a pressurizing-gas supply device, a fluidization-gas supply device, and a pulverized-fuel supply line. The hopper has a hollow to store therein pulverized fuel. The first nozzles are provided to the hopper. The second nozzles are provided to a vertically lower part of the hopper below the plurality of first nozzles. The pressurizing-gas supply device is configured to supply pressurizing gas to increase internal pressure of the hopper. The fluidization-gas supply device is configured to supply fluidization gas to fluidize the pulverized fuel in the hopper. The pulverized-fuel supply line is provided to a vertically lower part of the hopper. The pressurizing-gas supply device supplies pressurizing gas to the first nozzles and the second nozzles. The fluidization-gas supply device supplies fluidization gas to the second nozzles.

The present invention is a modular system for delivering material directly to a blender hopper. The system includes primary base and optional secondary base modules supporting surge hoppers which receive material from material containers. The surge hopper may then dispense the material directly and rapidly to the blender hopper by gravity feed. During continuous operation, exhausted material containers may be removed from the surge hoppers and replaced with full material containers as material empties from the surge hoppers. This allows steady, high-volume flow of material to the blender hopper.

A bulk storage bin is provided for grain and particulate material and includes a hopper bottom formed by a plurality of trapezoidal panels, each having upper and lower edges and opposite side edges. Flanges extend outwardly along each edge of each panel to provide a bolted flanged joint for adjacent panels. Plate assemblies extend along the upper edge of each panel to form a continuous 360 compression ring when the panels are assembled. Each flange has a portion extending behind the plate assemblies, with interior bolt holes. An access hole is provided at each end of each plate assembly for access to the interior bolt holes.

An inner plastic liquid container (25) includes a filling neck (41) in an upper wall (33) for filling the inner container and a front side outlet neck (40) for an outlet armature. A lower wall (28) interconnecting two side walls (30, 31), a rear wall (32) and a front wall (29) supports the container on a transport pallet (21) pallet base (26), which has an outer mantle (24) for receiving the container. The outlet neck is at a hopper bottom (39) of an outlet hopper (34) in the lower bottom wall. The outlet hopper has a front hopper wall (35) and inclined lateral hopper walls (36, 37) that are arranged at a hopper angle and each extend from a keel-shaped hopper base (38) to a lower edge (46, 47) of a side wall. A keel line (63) rises at another hopper angle from an outlet neck toward the rear wall.
