A conveyor belt (or belt conveyor) consists of two or more pulleys, with a continuous loop of material - the conveyor belt - that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler. There are two main industrial classes of belt conveyors; those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport industrial and agricultural materials, such as grain, coal, ores, etc. generally in outdoor locations. Generally companies providing general material handling type belt conveyors do not provide the conveyors for bulk material handling.
Conveyors are durable and reliable components used in automated distribution and warehousing.
The conveyor belt system
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.
The development direction of the transmission equipment belt conveyors for bulk materials is moving towards to large-scale, automatic sorting of materials, reduce energy consumption, and reduce pollution.
Large-scale includes large transmission capacity, large stand-alone length and the transmission angle. The length of the hydraulic conveyance device has reached more than 440 km. The stand-alone belt conveyor length is nearly 15 km and has a contact of several sets of belt conveyor road. Many countries are exploring long-distance, large capacity continuous transport of materials conveyor structure.
Expanding the scope of the use of the conveyor means developing conveyor equipment which can be corrosive, radioactive, flammable substances in the environment, work under conditions of high temperature and low temperature, and can transport a hot, explosive, and easy to knot groups, viscous materials.
Common conveyor belt type conveyor belt includes TD75, DT Ⅱ, and so on.
