A portable conveying apparatus for transferring particulate material comprises a conveyor supported on a trailer frame and operable to convey the material for subsequent discharge to a target location. A housing mounted to the trailer frame and substantially covering a top of the conveyor defines at least one inlet for delivery of material from a container to the conveyor. A flexible chute communicating each inlet and a container discharge to guide the material to the apparatus housing is carried on the trailer frame in a storage position so as to be transportable therewith. Within the housing, an upper guide surface converges to a central grate disposed at a transversely offset location from the respective inlet for central depositing of the material onto the conveyor. A suspension arrangement is operable to raise and lower the trailer frame between transport and operating positions so that a bottom of the trailer frame can rest on the ground to inhibit the dust emanating during use.

The disclosure relates to a support structure for supporting a belt of an enclosed belt conveyor between two transport units and a corresponding method. The support structure between two transport units includes a first end element having a main extension in a longitudinal direction, a width extension in a width direction orthogonal to the longitudinal direction, and a height extension in a height direction orthogonal to the longitudinal and the width direction. At least one guide assembly is arranged to engage opposite longitudinal edges of the belt. A first telescopic element is connected to the first end element, wherein an outer end of the first end element has a first end connector arranged to form a connection with a first transport unit.

A proppant conveyor system has: a tower; a bucket elevator; a telescopic conveyor boom mounted to the tower above a ground surface; the telescopic conveyor boom being connected to convey proppant from an outlet of the bucket elevator to a discharge point defined by the telescopic conveyor boom; and the telescopic conveyor boom being mounted to swing in lateral directions relative to an axis of the tower to reposition the discharge point. A method includes: conveying proppant up a bucket elevator, along a telescopic conveyor boom mounted on a tower above a ground surface, and into an inlet of a first storage bin at a well site; repositioning the telescoping conveyor boom over an inlet of a second storage bin at the well site by swinging the telescopic conveyor boom in a lateral direction relative to an axis of the tower; and conveying proppant up the bucket elevator, along the telescopic conveyor boom, and into an inlet of the second storage bin.

A control apparatus for use with a stone spreader vehicle improves the control of particulate material travelling on a conveyor. The control apparatus has an endless belt supported about a plurality of rollers, a capture volume at its leading edge for receiving the incoming particulate material on the conveyor, and a release volume at its trailing edge for releasing the particulate material from the control apparatus.

A method is provided for removing slack in a chain conveyor driven between a first sprocket and a second sprocket, the first sprocket and the second sprocket rotating in a first direction. The method includes: locking the second sprocket to prevent rotation of the second sprocket in a second direction opposite the first direction; operating the first sprocket in the second direction to position a slack portion between the first sprocket and the second sprocket; and removing at least one chain link from the slack portion.

A conveyor apparatus includes an endless conveyor belt wound around outgoing path side guide pulleys in turn along a helical conveyance path in a bent state where the belt is folded in two in a width direction such that an upper edge portion thereof is supported by the outgoing path side guide pulleys, and wound around returning path side guide pulleys in turn along the helical conveyance path in the bent state where the belt is folded in two in the width direction such that the upper edge portion is supported by the returning path side guide pulleys, and folded back at each turning positions of a horizontal conveyance unit located at an upper side and a horizontal conveyance unit located at a lower side of the support frame and being in an expanded state where the belt expanded in the width direction in a vicinity of the turning position.

A system is provided. The system includes a conveyor apparatus configured for conveying a material and a water content measurement system positioned about the conveyor apparatus for determining water content in the material. A dimension characteristic measurement system for detecting one or more dimension characteristics of the material is provided and a computer device is configured to manipulate data received from the water content measurement system and the dimension characteristic measurement system to determine a water content of the material.

A sand spreader includes a sand storage chamber. Two sand discharge ports are disposed below the sand storage chamber, and are an upper-layer staggered sand discharge port and a lower-layer sand pressing plate sand discharge port, respectively. The upper-layer staggered sand discharge port comprises a left side sand discharge plate and a right side sand discharge plate configured to intersect with each other. Horizontal staggered ports are formed in a position at the bottom of the two sand discharge plates, and vertical spacing between the staggered ports is adjustable. Also comprised is the lower-layer sand pressing plate sand discharge port, including left and right side sand pressing plates. Vertical sand discharge ports are disposed between the sand pressing plates on the two sides, and the width of the vertical sand discharge ports is adjustable, so as to further facilitate control over the amount of discharged sand.

A flowback tank cleaning system and method is described. A flowback tank includes a self-cleaning system. A flowback tank cleaning method may include moving solid debris collected at a bottom of a collection section of a flowback tank towards a lift auger using a cleaning auger or a conveyer belt extending along a length of the collection section, the bottom of the collection section including an angled trough, funneling solid debris towards the cleaning auger or conveyor belt by placing the cleaning auger or conveyor belt at a base of the angled trough, spraying fluid downward through a series of fluid outlets, removing the sand so moved by the cleaning auger or conveyer belt from the flowback tank using the lift auger, and removing the fluid from the flowback tank using a drain manifold below the cleaning auger or conveyer belt.

The disclosure relates to a drive arrangement for driving a belt of an enclosed belt conveyor. The disclosure further relates to a mobile haulage arrangement for continuously conveying fragmented material in a conveying direction and to a method for driving a mobile haulage arrangement. The drive arrangement for driving a belt of an enclosed belt conveyor include a conveyor drive assembly arranged to drive the belt of the conveyor run in the conveying direction, and a return drive assembly arranged to drive the belt of the return run in an opposite direction.
