These conveyor structures contain belts for moving bulk sulfur from railcars to storage piles and from the piles to ships. A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems. A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them.

Liu, Prediction of Belt Conveyor Idler Performance, Dissertation, Delft University of Technology, 2016, pg. 1] Along with the growing international trade in major bulk materials, there is an increasing demand for the transportation of bulk materials. Correspondingly, large-scale belt conveyor systems have been installed to meet the demand for higher capacity and longer distance application of continuous conveying of bulk materials (Harrison and Roberts, 1983; Lodewijks, 2011). [X. Liu, Prediction of Belt Conveyor Idler Performance, Dissertation, Delft University of Technology, 2016, pg. 1] The downtime of belt conveyor systems leads to stoppage of transportation of bulk materials, influencing subsequent material processing and production, and consequently causing serious financial loss. In a mining plant, for example, sixty percent of the plant downtime was attributed to conveyor problems (Steinberg, 1983). The downtime cost of belt conveyor systems may vary from one application to another.

The financial loss due to the downtime of belt conveyor systems can be in a range of 100,000 to 200,000 Euro per hour, considering the loss of the revenue from material conveying, and shutdowns of subsequent material processing facilities (Lodewijks, 2015).[X. Liu, Prediction of Belt Conveyor Idler Performance, Dissertation, Delft University of Technology, 2016, pg. 1] Conveyor production delays and reliability issues are generally a result of a failure in one of the three main components of a conveyor system. The belt, drives/gearboxes or the conveyor rolling elements.

Coal is removed by the open cut or strip mining method. Topsoil is first removed and placed on previously mined and re-contoured areas or stored separately for later reclamation. Overburden is then blasted to loosen the materials and is removed primarily by electric dragline to expose the coal seams. Excavators, loaders and haul trucks then remove the exposed coal to a collection point, where it is crushed and loaded on a overland belt conveyor.

A disadvantage is the loss of much useful floor space as a result of the presence of the necessary supports for the belt conveyor. A bigger distance over a smaller floor area can be bridged using a product lift or a vertical conveyor. A continuous conveyor or a discontinuous conveyor can be chosen as a vertical conveyor. Continuous conveyors can take the form of a spiral conveyor, an L-shaped conveyor or platform lift or a product lift fitted with a fork.

A discontinuous conveyor also called a reciprocating elevator, lifts the product on to a platform using a platform, roller conveyor or belt conveyor and then moves the platform with the product to another level. Because of the cycle time required for input and output as well as lifting/lowering movements, such a conveyor can only be used for smaller capacities. Continuous conveyors are more suitable for bigger capacities. There are two important solutions which can be used for this group.

The overburden is then delivered to the discharge boom, which transfers the cut earth to another machine for transfer to a spreader. This may be a fixed belt conveyor system or a mobile conveyor with crawlers similar to those found on the BWE. Mobile conveyors permanently attached to the excavator take the burden of directing the material off of the operator. The overburden can also be transferred directly to a cross-pit Spreader, which reaches across the pit and scatters overburden at the dumping ground.

The disc cutters create compressive stress fractures in the rock, causing it to chip away from the tunnel face. The excavated rock (muck) is transferred through openings in the cutter head to a belt conveyor, where it runs through the machine to a system of conveyors or muck cars for removal from the tunnel. Open-type TBMs have no shield, leaving the area behind the cutter head open for rock support. To advance, the machine uses a gripper system that pushes against the tunnel walls.

Above Llangwstennin Rectory was a shale quarry. The shale was crushed at the quarry and conveyed by a covered belt conveyor down to a rear residing just north of the main railway line where it was so store in silos to be taken to somewhere in England to extract paraffin wax. When the only road through Mochdre was along the old highway, Thornton steam lorries carrying ruby bricks used to stop on the bridge over the river and replenish their water tanks. These devices became commonplace around the world, but Mochdre was the first place they were ever used, around October 1860.

Measures to protect air quality include water sprays and sprinklers to control dust on dirt roads and disturbed areas, enclosures and water sprays at belt conveyor transfer points, baghouses on coal storage silos, and other requirements of the mine's Clean Air Act operating permit NN- OP 08-010. The permit is administered, monitored and enforced by the Navajo Nation Environmental Protection Agency (NNEPA), as authorized by the US EPA. Peabody maintains a network of PM10 particulate monitors to assess the effectiveness of fugitive dust control measures and ensure compliance with national ambient air quality standards (NAAQS). Monitoring data are reported quarterly to the OSM and NNEPA.

A shiploader mainly consists of a central column, an extendable arm or boom, a belt conveyor extending out of the boom structure, a slewing mechanism, and a loading chute to transfer product from a source conveyor or feeder. The boom can move front and back, up and down by separate drives so that it can fill the whole breadth of the ship hold and adapt to the ships increasing draught while it is loaded. The shiploader is essential to the global shipping industry. Globalization has promoted the need for international maritime ports to be equipped with efficient and durable shiploading machinery able to a handle the great variety of materials that enter into harbors within short time frames.
