Belt Converyors
Belt conveyor systems consist of two or more pulleys, with a continuous loop of material being the conveyor belt that moves rotationally around the drive and idler pulleys. The powered pulley is known as the drive pulley and the unpowered pulley is known as the idler. The pulleys are powered, moving the belt and the material on the belt forward. The main classes of belt conveyors (uses):
- General material handling such as belt conveyors moving boxes along, inside a factory.
- Bulk material handling such as belt conveyors used to transport industrial and agricultural materials, such as coal, grain, ores, and other minerals or materials with lumps.
The actual conveyor belt consists of multiple layers of material, conveyor belts can also be made out of rubber. Many belts in general material handling have two layers, the first layer is an under layer of material to provide linear strength and shape called a carcass and the second layer is an over layer called the cover.
The carcass is often created from a woven fabric, The most common carcass materials are polyester, nylon and cotton. The cover normally consists of various rubber or plastic compounds depending on the use of the belt. Covers can be made from many more exotic materials, silicone for high heats or gum rubber when traction is needed are just a few of these unusual applications.
Belt conveyors are probably the most common form of conveyors, Available as follows:
- light duty belt conveyors
- medium duty belt conveyors
- multiple band belt conveyors
- heavy duty belt conveyors
- bulk handling belt conveyors
