A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is part of an overall system that is used to move sand for use as proppant, and is fitted with a vibration system that facilitates the discharge of sand from the container.

A feeder is described for the conveyance of material such as overburden or mineral from a working site, the feeder comprising a feed device having a material receiving end having a material receiving apron suitable for receiving material such as overburden or mineral at a working site; a material discharge end distal of the material receiving end; an endless conveyor disposed between the material receiving apron and the discharge end so as in use to cause material received at the material receiving apron to be conveyed to the material discharge end; a chassis supporting the feed device; a transport carriage supporting the chassis and adapted to cause the feeder to be movable across a surface for deployment in use. A system A system and method for the movement of material from a working site for example via transport trucks are also described.

Disclosed is a blast furnace apparatus includes: a rotating chute; a profile measurement device configured to measure surface profiles of a burden charged into the furnace; and a tilt angle controller configured to control a tilt angle of the chute, in which the device includes a radio wave distance meter installed on the furnace top and configured to measure the distance to the surface of the burden, derives the profiles on a basis of distance data for the entire furnace obtained by scanning a detection wave of the distance meter in the furnace in a circumferential direction, and includes at least one of arithmetic units configured to command during rotation, on a basis of the surface profiles obtained, the controller to change the tilt angle of the chute, or a controller to change a rotational speed of the chute or a feed speed of the burden fed to the chute.

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.

The present invention relates to a bucket wheel excavator whose bucket wheel is rotationally drivable and is supported at a pivotable bucket wheel boom and to a method of controlling such a bucket wheel excavator. In accordance with the invention, a mass flow and/or material flow adopted on the removal conveyor after a specific advance on the pivoting of the bucket wheel at the predetermined pivot angle speed is/are determined over the pivot angle, a desired mass flow and/or volume flow is/are specified on the removal conveyor, and then the previously specified pivot angle speed is automatically corrected using the determined mass flow and/or volume flow and the specified desired mass flow and/or volume flow to then perform the pivot cycle at the corrected pivot angle speed of the bucket wheel.

A conveyance system includes a conveyance device including a first conveyance mechanism configured to convey freight supplied from a loader, and a second conveyance mechanism configured to convey the freight supplied from the first conveyance mechanism, a weight detection device configured to detect weight of the freight loaded on the second conveyance mechanism, and a control apparatus. The control apparatus includes a first conveyance control unit configured to control the first conveyance mechanism. The first conveyance control unit controls the first conveyance mechanism based on a detection value of the weight detection device.

The disclosure relates to a movable material processing apparatus for handling material such as ore, gravel, rock or the like, comprising: a foldable conveyor for discharging material from the apparatus, wherein said foldable conveyor is movable between a transport position and an operating position, said foldable conveyor comprising a loading block arranged at the loading end, and a discharge block extending from said loading block towards a discharge end, wherein said discharge block is pivotally coupled to said loading block along a first axis being perpendicular to a transport path of the foldable conveyor and parallel with a carrying surface of the foldable conveyor, and wherein said loading block is pivotally coupled to a support structure of said movable material processing apparatus along a second axis being parallel to said transport path.

There is provided a conveyor belt for marginal life prediction, in which wear of the degree of the conveyor belt can be well and visually recognized without stopping of the conveyor belt on operation, and the replacement time of the conveyor belt can be easily predicted in advance, thereby to predict and efficiently manage the life time of the conveyor belt. It was difficult to check abrasion extents step by step and exactly predict the life time in the conventional conveyor belts. Further, the accidents of carrying articles released out of the conveyor belt were frequently occurred since troughs of the conveyor belt are not formed enough, and the angle of the trough is so small. As the way of solving the problems as above, while the wear of the conveyor belt is progressed, and when the abrasion check colored rubbers, which are embedded inside the conveyor belt, are exposed outwardly and checked visually by eyes, the extent of the abrasion of the conveyor belt can be estimated and the exchange time of the conveyor belt can be well predicted. The number of the exposed abrasion check colored rubbers is well detected by installing the abrasion check colored rubbers in multi-layers with installation number reduced downwardly, thereby to enable anybody to predict the life time of the conveyor belt step by step precisely.

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.
