Belt Conveyors Manufacturers and Companies

From airport baggage handling, to assembly lines, to postal sorting, to the transport of humans along moving sidewalks or escalators, to the transport of materials like grain, sand, salt, coal and ore, the unique uses of belt conveyors are nearly endless. They reduce labor, allow for the rapid conveyance of large volumes of materials and save space. In addition, they can be installed nearly anywhere and they can move loads of all shapes and sizes, no matter how irregular. On top of that, they are much safer than moving machines like forklifts. The choice to purchase a belt conveyor is an easy one. One who does so, however, should pay attention to some safety regulations. In the United States specifically, he or she must make sure that the system is configured and installed in such a way that it adheres to the regulations of the Occupational Safety and Health Administration (OSHA). He or she should also take the time to educate workers on the proper protocol for working with the system. For the best results, one should call an experienced belt conveyor manufacturer.

The belt of a belt conveyor consists of one or more layers of material, such as the aforementioned polymer, PVC or something else. First, the belt is supported by an over layer called a cover and an under layer known, known as a carcass. While the cover is typically made of polymers, combination plastics or rubber, it can also be made of more unusual materials, like silicon, which conveys heat, or gum rubber, which provides traction. The carcass is made of plastic web, polyester, nylon, cotton or mesh. It provides the belt with linear length and shape. Typically, one or all of the belt conveyor pulleys are powered by an electric motor, linked via a sprocket and chain; these pulleys are known as drive pulleys. The chain is wrapped around the sprocket or sprockets, connecting the drive pulley and motor and, in doing so, the motor is able to power the drive pulley’s rotation. Any pulleys that are not motor-powered are called idlers. To regulate the speed of pulley rotation, a speed reducer is also connected to the motor, this time by a "c" face coupling or a v-belt. Once assembled, both the speed reducer and the motor are stored underneath the conveyor bed. Said conveyor bed may be either a solid metal frame bed or a roller bed. The latter is selected for heavy-duty applications, where it provides some friction reduction and stress relief. Note that some belt conveyors use tapered rollers and curved belting in order to achieve curves for going around corners. Sometimes, a belt conveyor can be much more simple, functioning as a slide and controlled by gravity.

These material handling apparatuses are generally divided into two main groups: polyurethane, or PVC/Pu conveyors, and modular belt conveyors. Since polyurethane is a food grade polymer, PVC/Pu belt conveyors are frequently used for food processing and pharmaceutical applications. Modular conveyor belts run on guides and do not rely on tracking devices. They are easier to maintain and, when compared to the former belt conveyor style, have superior durability. While a better make, they are slightly more expensive than PVC belt conveyors, and so do not necessarily enjoy vast popularity. Other types of belt conveyors include incline belt conveyors, enclosed belt conveyors, steel belt conveyors, portable belt conveyors and sandwich belt conveyors. Other types of conveyor systems in general include: heavy duty rear conveyor systems, spiral conveyor systems, vibrating conveyor systems, gravity skatewheel conveyor systems, gravity conveyor systems, electric track vehicle systems, drag conveyor systems, vertical conveyor systems, flexible conveyor systems and pneumatic conveyor systems.
