subject: Working Principle And Feature Of Belt Conveyor [print this page] Working principle and Feature of Belt Conveyor
Introduction
Belt conveyoris a machine transporting material in a continuous way by friction drive. It is mainly composed by rack, conveyor belt, belt roll, tensioning device and gearing. It can form a material delivery process between the initial feeding point and the final discharging point of jaw crusher .
It can transport not only granular material, but also work piece. Besides the pure material transporting, it can also form a rhythmic flow transport line complying with the requirements of various industrial production processes.
The belt conveyor can be used for horizontal transportation or inclined transportation in a convenient way, and widely used in modern industrial enterprises, such as: mine tunnel, mine surface transportation system, open-pit and concentrator.
Working principle
Belt conveyor is composed by two endpoint pulleys and a closed conveyor belt. The pulley that drives conveyor belt rotating is called drive pulley or transmission drum; the other one--only used to change conveyor belt movement direction--is called bend pulley. Drive pulley is driven by the motor through reducer, and conveyor belt dragging relies on the friction drag between the drive pulley and the conveyor belt. The drive pulleys are generally installed at the discharge end in order to increase traction and be easy to drag. Material is fed on the feed-side and landed on the rotating conveyor belt, then rely on the conveyor belt friction to be delivered to discharge end.
Feature
Compared with other transport equipment, such as Motorcycle, belt conveyor is the best efficient continuous coal transportation equipment with advantages of long transmission distance, large volume, continuous conveyor, etc., and operate reliably, easy to implement automation and centralization control; especially for high yield and efficient mine, belt conveyor has become the key equipment for coal mining and mechatronics technology.
The belt conveyor mainly has the following characteristics: the body can flex easily with a belt-warehousing, the tail can elongate or shorten complying with the coal face; directly lay on the roadway floor without setting up foundation; compact structure, light and handy rack and convenient disassembly. When the transmission capacity is big or transport distance is far, we can meet the requirements by equipping with intermediate drives. According to the requirements of transmission process, it can be transported by single transmission and also can be formed a horizontal or inclined transportation by multi-unit.
The belt conveyor is widely used in metallurgy, coal, transportation, utilities, chemical and other departments because of its features of big conveying capacity, simple structure, easy-to- maintenance, low cost and versatility.
The belt conveyor is also used in building materials, electricity, light, food, ports, ships and other departments.
