The higher initial cost of the belt conveyor is offset by the higher on going expense of trucks such as the cost of truck mechanical maintenance and tires the driver and the distance related cost of fuel Needless to say belt conveyors serve a vital link in the movement of numerous types of materials.
Material handling equipment is used to safely move large volumes of product and does so with great efficiency The most common form of this technology is the conveyor which uses mechanized movement to transport material from its inlet to its discharge end via belts chains augers buckets and more Visit our article on understanding conveyor systems to see the huge variety in conveyor.
The demanding conditions of the mining environment coupled with the weight and abrasiveness of many of the materials being transported take a toll on these conveyor belts resulting in costly maintenance and downtime Operational continuity is critical to the productivity of mine operations.
We offer a range of standard conveyor systems with belt widths from 600 to 1350 The advantage for clients is the speed at which they can be issued for fabrication constructed and commissioned Straight inclined at any angle to suit application Horizontal section then with a minimum of 180 M radius curved section to any incline angle to suit.
Magnetic Conveyor Belts This type of conveyor belt can transport materials that contain iron through equally spaced electromagnets that are placed within the bed of the conveyor Sandwich Belt Conveyors They use two face to face belts to securely carry items at steep inclines or even up a vertical run.
