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 material handling system includes a conveyor, an actuation unit, and a chute. The chute is mechanically coupled to the conveyor at a defined angle with respect to a surface of the conveyor. The chute includes an inlet defining a first end and a second end, where the first end of the inlet is mechanically coupled to the surface of the conveyor. Further, the chute includes at least one tube configured to be rotated by the actuation unit at a defined rotational speed. The chute also includes an outlet mechanically coupled to the at least one tube. In this aspect, the defined angle and the defined rotational speed is based on at least one of: physical characteristic of an item to be passed through the chute, a rate of inflow of the item through the inlet, and a rate of outflow of the item through the outlet.

A gravity-driven tire delivery apparatus includes a base and a tire delivery chute that extends vertically from the base. The tire delivery chute includes a wall including a braking projection mounted to the wall that extends into a travel path of a tire through the tire delivery chute. The braking projection is sized to allow the tire to pass by the braking projection once the tire is moved laterally by the braking projection.

An aerial roof height item receiving structure demonstrating novel solutions to issues of item drop damage, noise, aesthetic, weather, item temperature, and safety concerns related to aerial based item delivery systems is presented. A chimney like chute can be made high enough to avoid collisions with people or pets yet still safely receive items dropped into it from heights through the use of impact absorbing pads and a mesh box spring within the chute. Heat exchange with the building structure or active heating or cooling of the box spring mitigate snow, ice, and item temperature issues. A swing door to function as an aerial unit charging platform for added distance delivery can be added to the top of the chute. An item drop box placed at human accessible height can also be added to allow the chute to dual function for traditional item deliveries.

A bolt escapement device includes holding rails, a blade disposed downstream of the holding rails, and a chute disposed downstream of the blade. The blade includes: a blade body configured to reciprocate in a direction intersecting the holding rails to pass through a first position and a second position; a bolt passageway extending in the blade body in a direction acute to a moving direction of the blade body; and a closure portion provided on a side surface of the blade body. At least one of the holding rails and the chute is provided with bolt guides. When the blade body moves from the first position to the second position, a corner portion of the bolt passageway that is closer to the holding rails is inserted between a bolt having entered the bolt passageway and a subsequent bolt and the rail gap is closed by the closure portion.

A compact modular mobile aggregate processing system configured with no stand-alone inter-plant conveyors for decreasing the footprint of the system and an infinitely adjustable flow diverter(s) for increasing the control of and variation of output characteristics of the system; the system further including specialized folding conveyors.

Apparatus for orienting objects, including a conveying apparatus, wherein the conveying apparatus has an inlet for receiving the objects and an outlet and is configured to convey the objects in a conveying direction. In this case, the conveying apparatus has an orienting apparatus which at least partially extends along the conveying direction. The orienting apparatus has a first portion and a second portion, wherein the first portion and the second portion are arranged next to one another along the conveying direction, wherein at least one of the first portion and the second portion is configured as an aero surface, and wherein the objects are subjected to a different acceleration/braking action by the first portion and the second portion for orientation purposes.

An object orientation device includes a shaking stand and a slide provided on the shaking stand; the slide includes a sliding groove and a retaining member on the sliding groove. A retaining member is parallel to and extends along a sliding direction, and has a retaining surface parallel to a side wall of the sliding groove. The retaining surface and the side wall form an orientation space which is parallel to the sliding direction. After asymmetric objects are on the slide and shaken by the shaking stand, each object has a first end restricted into the orientation space, and has a seat orientation and moves towards a predetermined direction. Such object orientation device allows objects to be aligned in the slide and have consistent seat orientations; a printing equipment can print on the same position of each object. Additionally, a system and a method of orientation and printing are provided.
