Mechanical conveying is the most widely used form of materials handling in industry. Although a large number of devices are available, most systems conform to the basic elements in which belts, chains, or moving flights are used to move materials. Mechanical conveyor has advantages in terms of the ability to effect accurate control in the monitoring of material from one process to another. Further, by careful selection of construction materials, it is possible to design systems to meet a wide variety of operating conditions including corrosive environments and extremes of temperature. Belt conveyors are the mostly used and versatile mode of mechanical conveying systems. These are able to handle larger mass over longer distances and at a lower cost than most forms of conveying system. A belt conveyor is an endless length of flexible material stretched between two drums and supported at intervals. The importance of conveyor belt idler rolls within materials handling has led to the development of shell tubing and bearings specially designed for idler rolls. It is therefore reasonable to except idler manufacturers to utilize these components. However, the life and performance of these components in the finished idler roll will be largely dependent upon the design of the roll, the methods of manufacture and the fits and tolerances employed. The power absorbed by conveyor idler rolls is an important factor governing the selection of items such as motors, gearboxes, belting etc. Conveyor Idlers are generally manufactured in steel with bright bar shaft, single piece frame fitted with bearings for carrying, impact, and return Rollers.Conveyor belt idlers are a vital component of the economic development of the country. It is critical to the development of infrastructural sectors, such as coal and other minerals, irrigation and power, ports, steel, fertilizers, road construction, urban development and the like. India is fast emerging as a global manufacturing hub. India has all the requisite skills in product, process and capital engineering, owing to its long manufacturing history and higher education system. India's cheap, skilled manpower is attracting a number of companies, spanning diverse industries, making India a global manufacturing powerhouse. Thus the market for conveyor belt idler in the coming years is very bright as industries will cater the need for material handling. New entrepreneurs should venture into this field.
