The stocker is connected to the main body, with the plurality of stockers being arranged radially around the supply region, and a center axis of the supplier being directed to a center of the supply region.

A purpose of the invention is to provide a powder supply device having a dust collection unit to collect powdery dust released when powder is supplied from a lateral side, and having a space-saving and simplified structure. A powder supply device according to the present invention has a main body, a plurality of stockers and a dust collection unit. The stocker has a charge port and a supplier. The dust collection unit has a casing, an exhauster and a filtering member. The casing has a ceiling portion and a lateral side portion, with a side opposing said ceiling portion being opened to form a lid-shaped configuration. The lateral side portion has a notched portion into which the supplier is to be inserted. The filtering member is provided inside the casing and is positioned above the notched portion and below the ceiling portion in order to collect the powder.

A container assembly comprises a container and a base and is configured to be transported horizontally to a work site where it is raised to a vertical working orientation. A hoppered container floor directs material to a discharge opening in a center of the floor of the container. A plurality of chutes is fixed to the container assembly and each slopes downward and outward from a chute input, located under a central portion of the hoppered floor, to a corresponding chute output. A distributor assembly mounted under the discharge opening receives granular material from the discharge opening and directs same into any one of the chute inputs. When loaded on a gooseneck trailer the container extends over the hitch assembly providing increased volume and capacity.

A hopper and method for transferring raw material, which can prevent segregation due to the impact caused by falling of the raw material powder when different types of raw material powders are transferred. The hopper for a raw material powder according to one embodiment of the present disclosure includes: a hopper body having an inner space in which the raw material powder is stored and including an outlet which is formed through the lower end thereof and through which the raw material powder is discharged; a transfer pipe to which the raw material powder discharged through the outlet is transferred and which has a region, through which the raw material powder is transferred, divided into a plurality of regions; and a slide gate unit disposed between the outlet and the transfer pipe to open or close the transfer pipe while adjusting a degree of opening of the transfer pipe.

Provided is a tank container which can accommodate and transport powder formed of hazardous material powder or the like while suppressing the contact of the powder with moisture in the air and an increase in temperature to a temperature equal to or higher than a predetermined temperature, and which can also easily discharge the powder, and a method of manufacturing the tank container. A tank container includes: a tank main body portion formed into an airtight cylindrical shape, which is configured to accommodate powder therein, and which is closed at both ends along a longitudinal direction; a plurality of accommodation and discharge portions, which are arranged so as to be adjacent to each other along the longitudinal direction in a lower portion of the tank main body portion, which have base end portions each airtightly joined to an inner wall of the tank main body and to an adjacent portion, and which have distal end portions each formed into an inverted tapered shape so as to protrude outward respectively from openings formed on an outer peripheral surface of the tank main body portion; a heat insulating portion formed on the outer peripheral surface of the tank main body portion; and a container frame portion having the tank main body portion fixed thereto.

Described is a cementitious material delivery system having at least one material box (10) with a lower access point (16) that is connected to a collection hopper (22). Also described is a cementitious material delivery system having at least one container (38) with an unloading end (42) that is located proximate to a collection hopper (22). The at least one container (38) can be positioned on at least one shelf (18) that can be raised so that the unloading end (42) is tilted toward the collection hopper (22).

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The container is mounted in a cradle that tips downward in arcuate motion for discharge or proppant through a top opening The tipping mechanism may be driven by a system of gears or a hydraulic ram.
