A hopper and a mineral material processing plant. The hopper includes hinged side walls configured to be pivoted into a first position and a second position and a connection wall attached between the hinged side walls. The connection wall includes a flexible member and is configured to fold together in response to the hinged side walls being pivoted from the first position to the second position.

Embodiments of the present disclosure describe a system for capturing dust and dust-laden air caused by the agitation, movement or transfer of particulate material. The system includes a dust collection assembly positioned proximate and associated with the delivery of particulate material to capture dust particles released by movement and settling of the particulate material when being dispensed and delivered. The dust collection assembly is positioned to direct an air flow in a flow path overlying the dust particles to capture the dust particles and move the dust particles away from the proppant thereby reducing risk of dust exposure.

A melter melts particulate hot melt adhesive into a liquefied form. The melter includes a heated receiving device having an interior with an inlet that receives the particulate hot melt adhesive and an outlet. The heated receiving device melts the particulate hot melt adhesive and directs the liquified hot melt adhesive to the outlet. A prepackaged container holds a supply of the particulate hot melt adhesive and includes an outlet. A particulate hot melt adhesive feed device allows the particulate hot melt adhesive to be directed from the outlet of the prepackaged container to the inlet of the heated receiving device.

A conveyor system for conveying material may include a conveyor belt, a feeding mechanism for feeding materials to be conveyed onto the conveyor belt, and a belt system in which the conveyor belt is guided. The belt system may include a first belt-shaping device with which the conveyor belt can be shaped into a U shape. Thus the material to be conveyed may be brought from a substantially flat shape into the U shape. A second belt-shaping device of the belt system may shape the conveyor belt downstream of the feeding mechanism in the conveying direction to form a closed tube. The feeding mechanism may include a catching region configured such that material to be conveyed accumulates therein and forms an impact surface onto which the material to be conveyed can be fed.

A picking device for piece goods is disclosed, in which cleaning of the picking device is facilitated. The picking device may include a shelf row having shelf bases, each including a plurality of storage chutes, and a retrieving device, via which piece goods can be retrieved. A shelf base may include a frame structure, chute partitions, chute bases, and blocking devices, which are coupled to a control device. Two chute partitions and one chute base may define one elongate storage chute, assigned to each chute base is a support device, on which the chute base rests and which is designed such that another chute base can be slid between the resting chute base and the support device. Assigned to each chute base is a holding means, which prevents the chute base from sliding in the longitudinal direction of the storage chute when the chute base is on the support device.

An additive manufacturing system can include a powder dispenser; a gate adjacent to the powder dispenser; a recoater blade system; and a control operable to move the gate with respect to the powder dispenser to selectively dispense powder from the powder dispenser.

A battery aligning device includes an inlet through which a first cylindrical battery is input, an outlet from which the first cylindrical battery is discharged, regulating plates constituting a slit in a path from the inlet to the outlet, and a support member which supports one end portion and the other end portion of each of the regulating plates, in the regulating plates, a length from the one end portion to the other end portion is longer than a length of the first cylindrical battery, an X-Z cross-section has a non-linear shape, in an interval between the one regulating plate and the other regulating plate, a facing interval between surfaces is larger than a diameter of the first cylindrical battery, and when a line segment having the same length as that of the first cylindrical battery is in contact with the regulating plate at two points on the X-Z cross-section, a distance between the line segment and the regulating plate is arranged at an interval smaller than the diameter of the first cylindrical battery.

An apparatus for dividing horticultural products, propelled by a fluid for transport from an intake region connected to an upstream station to an evacuation region connected to a downstream station. The apparatus includes a supporting frame for a contoured floor, which is arranged so that a first edge is at said intake region and is arranged so that a second edge, arranged opposite the first edge, is at the evacuation region. The contoured floor includes a plurality of lanes interposed in a parallel arrangement between the regions and have a substantially V-shaped transverse cross-section so as to produce the progressive conveyance and alignment of the horticultural products in transit along the bottom of each lane.
