In modern industry, the overland belt conveyor system is widely designed for handling bulk materials like iron ore, copper ore, bauxite, limestone, sand, aggregate, etc. Rough, mountainous and fragmented terrain with extreme differences in height is nothing overland belt conveyors can’t handle. The routing of the overland belt conveyor system is adapted to the geographic and topographic conditions by combining horizontal and vertical curves.
Our desire to collaborate and move the conveyor industry forward has lead to pioneering work with:
Long Distance Conveyor Design: Design of a conveyor system focused on proper major component selection through design trade-off studies and customer feedback.
Dynamic Analysis of Conveyors: Avoid common conveyor design flaws such as belt sag and drive slip by accurately modeling the starting and stopping of a conveyor while accounting for the change in stretch of the belt.
Transfer Chute Design by Discrete Element Method: The simulation of bulk materials flowing through transfer chutes is one of the most difficult engineering problems conveyor engineers face. SKE pioneered the use of DEM in belt conveyor transfer design. We know what the problems are and how to solve them.
Survey and Assessments: If conveyor downtime is eating into your production, a plant wide audit might reveal some simple changes that could have huge benefits. Or perhaps one or two problems always seem to pop up at regular intervals. SKE can help identify and eliminate these issues.
Options for overland conveying vary according to numerous factors, including capacity, length, terrain, geotechnical properties, and the environment.
The technology has been developing over the past decades and continues to do so. The technology and components are readily available from many suppliers. The baseline is a solid foundation of design and operation experience. However, technical risks are still associated with these systems at the ultimate limits of existing knowledge and experience.
Overland conveyor belt: Conventional large-capacity, long-distance overland conveyors use a steel cord belt with a single layer of parallel steel cords to carry the belt tension. Vulcanized splices are used to connect belt segments, and are the limiting factors in a belt’s carrying capacity. Current findings have led to the acceptance that splice safety factors can be reduced from previous empirical numbers, which had a significant impact on carrying capacity.
Overland conveyor idlers: The number of idlers installed directly affects the cost of the conveyor, and idler spacing has increased significantly for overland conveyors. The selection of the idler bearing, seal, and lubricant also has a significant effect on conveyor life, noise emission, and energy consumption.
Overland conveyor tension system: There are numerous options for tension the belt on a conventional overland conveyor, which allow the system to be very flexible and cater to numerous applications and loading conditions. Current knowledge of dynamic conveyor behavior and take-up control has allowed overland conveyors to be designed with sophisticated take-up management that reduces belt tension and overall costs.
Conveyor Drives: Conventional conveyors are typically driven and braked at one or more locations along the conveyor. The designs, locations, and controls of these drives, combined with take-up and splice technology, have allowed these conveyors to perform at capacities and lengths inconceivable 25 years ago. Several types of intermediate drives are available, from the tripper style through the booster style to the power-strip style, which does not need trippers.
The overland belt conveyor system is mainly used in bulk material handling industry. You can use it to transfer large quantity of bulk material in a certain hour. Our customers adopt it to convey iron ore, copper ore, limestone, granite, basalt, bauxite, phosphate rock, etc. In port, it is often combined with ship loader.
SKE is overland conveyor belt system manufacturer in China. We provide the structure system includes top and return idlers, brackets, stands, spreader bars and associated hardware. West River Conveyors can design and build a complete structure with all these components or supply just parts as needed. If you need any help about our overland conveyor, you can contact us.
