Abstract:
A reclaimer system for removing solid material from a fluid-filled pit. The reclaimer system comprises a screen, a pump, and a conveyor. The screen is positioned within the pit such that the pit is divided into a first portion and a second portion. The screen includes a plurality of openings. The pump is positioned in the first portion of the pit and includes at least one intake port in fluid communication with the first portion of the pit. The conveyor is positioned in the second portion of the pit adjacent the screen. The conveyor includes a frame, a belt, a plurality of flight members mounted on the belt, and a conveyor deck. The flight members are mounted on the belt and move the solid material along the conveyor deck, carrying the solid material out of the pit.
Abstract:
Wing pulleys that engage a conveyor belt during conveying operations are described. The wing pulley includes a central reinforcing disk that strengthens and stabilizes the pulley.
Abstract:
A cartridge assembly for use in a load zone support assembly is disclosed. The cartridge assembly includes a shaft configured to be coupled to an idler frame of a belt conveyor system. The cartridge assembly further includes a support plate coupled to the shaft and a wear pad coupled to the support plate.
Abstract:
The object of the invention is an apparatus for storage of wood chips in a curved-top stockpile the apparatus consisting of a central tower, which supports a conveyor for loading the chips and a beam-like turning pile composer, and a unloading beam supported on ground level on the lower part of the tower as well as on supporting wheels and furnished with unloading devices for transporting the wood chips towards the center of the apparatus. The central tower is furnished at one side with a tubular ex-central opening, and the tower occupies a central tube for delivering the wood chips either upwards or downwards from the opening. The unload drive for the unloading device is positioned inside the tower and the stockpile yard is furnished with a wall at the reach of the unloading device.
Abstract:
Toggle retainers are disclosed for toggle connection assemblies of conveyor pans of a chain scraper conveyor or guide troughs of a mining machine guide used in underground mining operations. The toggle retainers feature laterally open toggle pockets into which toggles can be readily inserted. The toggles have toggle heads that are connected in one piece with one another, with at least one of the toggle heads having a bolt tongue. A toggle retainer can be affixed to one of the toggle pockets by extending the retainer under one or more wall projections. The toggle retainer is designed so as to have multiple parts, with a bolt element, in the assembled state, extending over the bolt tongue and under the wall projections. To ensure a secure placement of the toggle in the toggle pockets, a filler element can be form-fittingly inserted between the bolt element and the back wall of the toggle pocket and connected to the bolt element via a screw joint.
Abstract:
The rotary disc conveyor system is formed of a series of units or pans linked together to form a continuous conveyor run. Each of the pans preferably includes a pair of rotary discs thereon, with all of the discs of the system rotating simultaneously and unidirectionally to convey material along the conveyor run. Each disc includes a series of generally radially disposed vanes thereon, to assist in sweeping the material along the conveyor. Guides may be installed along either side of the system, between each disc, to facilitate material flow and restrict return flow. Mechanical, hydraulic, or electrical power may be used to provide rotation of the discs. The rotary disc conveyor is particularly well suited for use in longwall coal mining for removing loose coal from the mining head and conveying it along the face of the wall to another transport system for removal from the mine.
Abstract:
An apparatus is provided for modifying a belt conveyor for enabling use of varying belt widths. The apparatus includes a pair of first mounting feet having slots and coupled by a cross member, wherein the first mounting feet are coupled to the cross member enabling the slots to mate with holes disposed on the frame, the apparatus further has second mounting feet having slots and adapted to couple to a first upper idler and a first lower idler, the apparatus further having supports coupled to opposite ends of the cross member, wherein a first end of the supports is coupled to the cross member and a second end is coupled to the second mounting feet. The apparatus is further characterized in that the cross member has a selectable length such that a second upper idler having a width greater than the first upper idler and a second lower idler having a width greater than the first lower idler can be coupled to the conveyor frame.
Abstract:
There is provided a material categorisation and transportation system including a plurality of mine vehicles for transporting material within a mine site from a first location in the form of a blast site to a second location. The system includes a sensing device for actively sensing chemical property characteristics of raw blasted mined material such that the raw material can be categorised into a plurality of material categories based on the sensed characteristics. The system further includes a loading device located at blast site for loading the raw material into a predefined one of the mine vehicles based on material category for transportation to the second location. The system is such that each of the mine vehicles only carries raw material of a predetermined one of the material categories.
Abstract:
A method for reducing the turbidity of as-mined sand comprising adding water to the as-mined sand to increase its moisture content to between about 5% and about 40% by weight, mixing the sand and water, piling the wet sand on the ground, allowing the sand to rest for a predetermined period of between about 12 hours and about 3 days, then harvesting less than all of the sand from the pile as reduced turbidity sand.
Abstract:
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.
