A proppant delivery assembly receives and supports a plurality of containers having proppant stored therein. A cradle has a top surface which receives and supports the plurality of containers when positioned thereon. The cradle enables the plurality of containers to dispense the proppant stored therein. A proppant mover is positioned to underlie and extend along the top surface of the cradle aligned with the plurality of containers to receive proppant from the plurality of containers. The proppant mover carries proppant away from the plurality of containers. A chute is coupled to the cradle for receiving proppant from the proppant mover and directing the proppant to a blender hopper. A hood assembly is disposed at an end of the chute opposite the proppant mover for directing a vacuum air flow that removes a volume of air containing proppant dust particles directed from the chute. The hood assembly includes a curtain extending about a perimeter of the hood assembly and downward therefrom to at least partially define the volume of air being removed by the hood assembly.

A delivery system for feeding particulate matter to a target location at a well site, including a transportable conveyor belt assembly; one or more silos in fluid communication with a particulate supply line, each of the silo inlets extending through a side wall of the respective silo and disposed at a different location from the others along a longitudinal axis of the respective silo; and for each silo an enclosed chute detachably attachable thereto so as to receive into the chute particulate matter gravity fed out of the respective silo and convey such matter into the housing of the conveyor belt assembly. The silos, the chutes and the housing enclose the particulate matter as it passes from the silos through the chutes and conveyor belt assembly to the target location, to inhibit the release of dust generated from movement of the particulate matter from the silos to the target location.

The present invention discloses a feeding system that comprises a plurality of material tanks having air outlets, a plurality of blowers, a dust remover having an air inlet, and a connecting pipe. Air inlets of the plurality of blowers are in communication with the air outlets of the material tanks in one-to-one correspondence. The first end of the connecting pipe is in communication with the air inlet of the dust remover, and the second end of the connecting pipe is movable between being connected with the air outlet of a first one of the plurality of blowers and being connected with the air outlet of a second one of the plurality of blowers. The disclosed feeding system a simple structure and zero dust leakage. Also disclosed is a glass production apparatus that comprises the disclosed feeding system.

The present invention relates to a loading device for loading particulate material, comprising a body with a first opening and a second opening, wherein a gasket is arranged at the first opening. The present invention also relates to a mixing device with a loading device according to the invention and a method of loading particulate material using the loading device according to the invention.

An apparatus for rotary dumping of rail cars, including a material receiving pit. A rotary rail car dumper includes a rotational frame supporting at least one baffle. The rotational frame is configured to dump a load from a rail car during rotational motion of the rotational frame between an upright position wherein the entire load is in the rail car and a dumping position wherein the load can exit the rail car. A backside airflow diverter is located beneath the rotational frame and includes a curved upper surface. A lower margin of the at least one baffle contacts the curved upper surface during at least part of the rotational motion of the rotational frame.
