Abstract
A conveyor belt system essentially consists of an endless belt of elastic material connected between two flat pulleys and driven by the rotation of one of the pulleys by a direct current motor. Usually, the material is fed to the belt near the other end of the pulley. The moving belt that carries the material to the drive pulley tends to sag between the two end pulleys due to its own weight. Rubber conveyor belts are commonly used to transport items with uneven bottom surfaces, small items that fall between rolls, or product bags that sag between rolls.
Highlights
As the flat belt is always under tension, it is subject to elongation, which causes loosening of the pulleys and loss of tension and power
The conveyor system has achieved a dominant position in the transportation of bulk materials due to a number of inherent advantages, such as economy and operational safety, reliability, versatility and a virtually unlimited range of capacities
AG Thakur (2015) - This work presents an application of the concept of simultaneous engineering and the principles of design for manufacturing and design for assembly, several critical parts of conveyors were investigated for their cost of functionality and ease of assembly in the general conveyor system
Summary
As the flat belt is always under tension, it is subject to elongation, which causes loosening of the pulleys and loss of tension and power. That is why some type of belt tensioning device is incorporated into the system. This tensioning device is known as a retraction arrangement. The conveyor system has achieved a dominant position in the transportation of bulk materials due to a number of inherent advantages, such as economy and operational safety, reliability, versatility and a virtually unlimited range of capacities. Conveyor belts are generally of fairly similar construction, consisting of a metal frame with rollers at each end of a flat metal bed
