Belt Conveyors

A belt conveyor as the name implies is comprised of a durable material (the belt) that encircles two or more rollers. One of the rollers has a drive mechanism (usually an electric motor) attached to it either directly or through a gear reducer. The other roller is usually unattached to any type of drive and allowed to roll freely.

Belt Conveyor, Automation System Belt Conveyors are the most commonly used bulk handling conveyors in history due to their reliability, versatility, and range of capacities. Materials from fine powders to large, lumpy stone or even discrete parts can be handled on a belt conveyor. This type of conveyor can exist as a single wide belt or two or more "V" belts. Usually a single wide belt is used in an application where a single item is to be conveyed, that has little or no chance of separating. For example, you might use a single conveyor belt system to convey a small section of carpet, a tray of parts or other single unit materials from one location to another. automation system

You might use a "V" belt type system when handling material that could break or come apart. If the material does come apart, you want the broken or detached material to fall through the belts and onto the floor rather than impeding the material behind it. This type of belt conveyor is good for handling glass and other breakable items.

Conveyor belts are available in widths up to 100 inches. It is the most costly part and the component is most susceptible to damage. The parts that make up the belt are: the covers (top and bottom), and the carcass. The carcass provides: the tensile strength needed to start and move the loaded belt, the transverse and longitudinal flexibility required to allow the belt to both support the load and conform to the shape of the idlers when empty and to wrap around pulleys, the the strength to resist impact forces. The cover's main function is simply to protect the carcass from damage. The material that a belt is made of can be made from anything from very common and economical cloth / rubber material all the way to more exotic heat and chemical resistant materials. You must be knowledgeable of your application and pick a belt that best suites the product that you convey.

The power required to drive a belt conveyor is derived from the tensile forces required to propel or restrain the belt at the design speed. These include: the resistance of the drive, conveyor components, and material; the acceleration of the material; and the gravitational forces required to lift or lower the material. A wide variety of belt conveyors are used in material handling systems. The most popular types are the; flat, telescoping, trough, and magnetic belt conveyor.
