A conveyor belt, in particular a tubular conveyor belt or a pipe conveyor belt or a pouch conveyor belt, which has a belt body that has a carrying-side cover sheet, a profiling that is formed substantially perpendicular to the surface of the carrying-side cover sheet being formed on the carrying-side cover sheet, the profiling having a number of transverse-strip profiling regions along a longitudinal direction of the carrying-side cover sheet.

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 system for conveying material may include a conveyor belt, a feeding mechanism for feeding materials to be conveyed onto the conveyor belt, and a belt system in which the conveyor belt is guided. The belt system may include a first belt-shaping device with which the conveyor belt can be shaped into a U shape. Thus the material to be conveyed may be brought from a substantially flat shape into the U shape. A second belt-shaping device of the belt system may shape the conveyor belt downstream of the feeding mechanism in the conveying direction to form a closed tube. The feeding mechanism may include a catching region configured such that material to be conveyed accumulates therein and forms an impact surface onto which the material to be conveyed can be fed.

A conveyor assembly for moving material includes a plurality of chains each defining a longitudinal axis, and a plurality of flights coupled to the at least two chains and configured to contact and move the material in a direction parallel to the longitudinal axes. Each of the plurality of flights extends along a central axis oriented oblique with respect to the longitudinal axes. Each flight includes a first portion offset from a second portion in a direction parallel to the longitudinal axes.

A device and method for transferring solid particles between zones of different ambient conditions is disclosed. A piston chamber comprising a solids inlet, a solids outlet, and a piston is provided. The solids inlet is adjacent to a source of solid particles, the source being at a first ambient condition. The solids outlet is adjacent to a solids receptacle, the solids receptacle being at a second ambient condition. The piston comprises a hollow. The piston traverses back and forth across the piston chamber such that the hollow is moved alternately adjacent to the solids inlet and the solids outlet. The solid particles pass into the hollow as the hollow is adjacent to the solids inlet, and pass out of the hollow as the hollow is adjacent to the solids outlet.

Each flight includes a first portion offset from a second portion in a direction parallel to the longitudinal axes.

Provided is a pressurizing system which includes: a pressurizing nozzle configured to supply a pressurizing gas into a hopper (3) where pulverized coal is accumulated; a filter configured to face a space in the hopper (3) where the pulverized coal is accumulated, and to allow the pressurizing gas to pass through the filter, the filter being provided at an end of the pressurizing nozzle; buffer tanks (5a), (5b) in which a pressurizing gas to be supplied to the hopper (3) is collected at a first predetermined pressure; and a pressure control means configured to start, at a time of starting pressurization of the hopper (3), supply of a pressurizing gas at a second predetermined pressure which is lower than the first predetermined pressure of the pressurizing gas collected in the buffer tanks (5a), (5b).

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.

Provided is a pallet car for the transport of bulk material for a thermal treatment thereof. The pallet car comprises a frame with at least two opposed cross-beams on which grate bars rest and two end pieces each connecting the cross-beams with each other, which each include at least two rollers and at least one side wall. In the pallet car, the grate bars and/or the side walls and/or the insulating plates are made of a ceramic fiber composite, wherein the fibers are metallic and high-temperature resistant.

A conveying system for conveying a divided material forming a pile includes a trench extending in a main direction. The trench is under a reception location of the pile along an direction of elevation. The conveying system also includes a conveyor extending along a route, which includes at least one reception portion extending into the trench. The conveying system further includes a number of protectors extending across the trench above the reception portion in the direction of elevation, and a carriage adapted to move along the trench and including a first actuator adapted to successively move each protector in the main direction.
