Introduction A conveyor system is a common piece of mechanical handling equipment that moves materials from one location to another Conveyors are especially useful in applications involving the transportation of heavy or bulky materials in Industries. Conveyers are also used in general material handling such as those moving boxes along inside a factory, such as agricultural materials, such as grain, salt, coal, ore, sand, overburden and more.

Belt Conveyor Belt- are the most common type of conveyors and are very versatile. Conveyor belts are used in a wide variety of material transport applications such as manufacturing, food processing, and heavy industry.
Working Of belt The Belt is provided with two rollers . One is the Drive and other is the Tension Roller. Drive roller is driven mechanically by a motor . Tension roller can be moved forward and backward directions to release or tight the belt with our requirement.
Belt Material Belts are typically made from cotton, canvas, Kevlar, nitrile, nylon, polyester, polyurethane/urethane, PVC, rubber, silicone, steel cord, Teflon, wire mesh or weave.
Design of belt The Belt consists of one or more layers of material.Generally contains two layers. 1.) An under layer -to provide linear strength and shape called a carcass(polyester, nylon and cotton) 2.) An over layer called the cover. (rubber or plastic compounds)
Properties of Belt Flexibility Transverse rigidity Low mass per unit length High strength Simplicity and inexpensive Longer life Should not stretch under normal working stresses ,i.e., low relative elongation. Wear resistant Fire resistant
Advantages of Belt Conveyor Belt conveyor can be used for abrasive, wet, dry, sticky or dirty material. Higher capacity can be handled than any other form of conveyor at a considerably lower cost per tonne per kilometer. Longer distances can be covered more economically. It can be horizontal, incline or decline or combination of all. It is considered a labor saving system that allows large volumes to move rapidly.
Limitations The belt needs higher initial tension. Conveying of sticky material is associated with problems of cleaning and discharge causing poor productivity. Higher elongation of the belt (4% elongation may take place at the working load).
Conclusion Belt Conveyor systems can improve efficiency and help to reduce repetitive lifting and carrying. Many industries use Belt conveyor systems to transport raw materials and products through the stages of a process. We can say that the Conveyor system is the backbone of an industry, if there is any failure in conveying system that needs to be fix as soon as possible.
