Belt conveyors can now be manufactured with curved sections which use tapered rollers and curved belting to convey products around a corner. These conveyor systems are commonly used in postal sorting offices and airport baggage handling systems. A sandwich belt conveyor uses two conveyor belts, face-to-face, to firmly contain the item being carried, making steep incline and even vertical-lift runs achievable.
Belt conveyors are the most commonly used powered conveyors because they are the most versatile and the least expensive. Product is conveyed directly on the belt so both regular and irregular shaped objects, large or small, light and heavy, can be transported successfully. These conveyors should use only the highest quality premium belting products, which reduces belt stretch and results in less maintenance for tension adjustments.
Belt conveyors can be used to transport product in a straight line or through changes in elevation or direction. In certain applications they can also be used for static accumulation or cartons.
Primitive conveyor belts were used since the 19th century. In , Thomas Robins began a series of inventions which led to the development of a conveyor belt used for carrying coal, ores and other products. In Richard Sutcliffe invented the first conveyor belts for use in coal mines which revolutionized the mining industry. Hyacynthe Marcel Bocchetti was the concept designer.
Goodrich Company patented a conveyor belt that it went on to produce as the Turnover Conveyor Belt System.
Incorporating a half-twist, it had the advantage over conventional belts of a longer life because it could expose all of its surface area to wear and tear. The belt consists of one or more layers of material. It is common for belts to have three layers: a top cover, a carcass and a bottom cover. The purpose of the carcass is to provide linear strength and shape.
The warp refers to longitudinal cords which characteristics of resistance and elasticity define the running properties of the belt. The weft represents the whole set of transversal cables allowing to the belt specific resistance against cuts, tears and impacts and at the same time high flexibility. The most common carcass materials are steel , polyester , nylon , cotton and aramid. The covers are usually various rubber or plastic compounds specified by use of the belt.
Today there are different types of conveyor belts that have been created for conveying different kinds of material available in PVC and rubber materials. Material flowing over the belt may be weighed in transit using a beltweigher. Belts with regularly spaced partitions, known as elevator belts , are used for transporting loose materials up steep inclines. Belt Conveyors are used in self-unloading bulk freighters and in live bottom trucks.
Belt conveyor technology is also used in conveyor transport such as moving sidewalks or escalators , as well as on many manufacturing assembly lines. Stores often have conveyor belts at the check-out counter to move shopping items.
Ski areas also use conveyor belts to transport skiers up the hill. The longest belt conveyor system in the world is in Western Sahara. It is 98 km 61 mi long, from the phosphate mines of Bu Craa to the coast south of El-Aaiun.
The longest conveyor system in an airport is the Dubai International Airport baggage handling system at 63 km 39 mi. It was installed by Siemens and commissioned in , and has a combination of traditional belt conveyors and tray conveyors. Boddington Bauxite Mine in Western Australia is officially recognised as having the world’s longest and second-longest single belts with a kilometre-long 19 mi belt feeding a 20 km This system feeds bauxite through the difficult terrain of the Darling Ranges to the Worsley Alumina refinery.
The longest single-belt international conveyor runs from Meghalaya in India to a cement factory at Chhatak Bangladesh. The conveyor is actuated by three synchronized drive units for a total power of about 1. The conveyor belt was manufactured in meter lengths on the Indian side and meter lengths on the Bangladesh side, and was installed on-site by NILOS India. The idlers, or rollers, of the system are unique [ citation needed ] in that they are designed to accommodate both horizontal and vertical curves along the terrain.
Dedicated vehicles were designed for the maintenance of the conveyor, which is always at a minimum height of 5 metres 16 ft above the ground to avoid being flooded during monsoon periods.
