Belt Conveyors for bulk materials: Take up Arrangement: All belt conveyors require the use of some form of take up device for the following reasons: 1. To ensure adequate tension of the belt leaving the drive pulley so us to avoid any slippage of the belt. 2. To ensure proper belt tension at the loading…
Conveyor Take-up Arrangement: All belt conveyors require the use of some form of take-up device for the following reasons: To ensure adequate tension of the belt leaving the drive pulley so as to avoid any slippage of the belt To ensure proper belt tension at the loading and other points along the conveyor To compensate…
Pulley Belt Conveyor Pulley: The diameters of standard pulleys are: 200, 250, 315, 400, 500, 630, 800, 1000, 1250, 1400 and 1600 mm. pulley may be straight faced or crowned. The crown serves to keep the belt centered. The height of the crown is usually 0.5% of the pulley width, but not less than 4…
Types of Belt Conveyor Drives: Single Unsnubbed Bare / Lagged pulley Drive Snubbed Bare / Lagged Pulley Drive Tandem Drive Special Drives Single Unsnubbed Bare / Lagged Pulley Drive: This is the simplest drive arrangement consisting of a steel pulley connected to a motor and the belt wrapped round it on an arc of 180°….
Drive arrangement: In belt conveyors the driving power is transmitted to the belt by the driving pulley which is rotated by an electric motor. The basic mechanism of transmission of power from the pulley to the belt is based on the theory of friction drive. The fundamental equation for a belt conveyor drive is given…
Idlers: Conveyor belts are usually supported on idler rollers. In some cases they are supported by solid wood or runway of steel sheet or a combination support comprising of the two types of supports placed alternatively. There are two basic types of idlers: Carrying idlers Return idlers Carrying Idlers: The most commonly used type of…
Belt Conveyor parts: The desirable properties of an ideal belt material are: High Strength, Low self weight, Small specific elongation, High Flexibility, High resistivity to ply separation Low hygroscopic Long service life In general Reinforced Rubber Belts meet these requirements better than any other material. In general, a conveyor belt consists of three elements: Top…
Conveyor layouts: Belt conveyors can be designed for practically any desired path of travel. It should be noted that transfer between conveyors should be avoided where possible due to additional wear on the belts at the loading points. Some of the profiles shown below: Horizontal Conveyor Decline Conveyor Inclined Conveyor Overland Conveyor Popular on BlogMech…
Types of conveyor: Troughed belt conveyor Flat belt conveyor Troughed belt conveyor: Troughed belt conveyor is that in which the belt forms a trough on the carrying side while running over idler rollers which are either in set of 5 rolls, 3 rolls or 2 rolls. The troughing angle adopted are: 15°, 20° , 25°…
Selection of Conveyor belt: To select the correct conveyor belt for your application involves a large number of considerations. Final selection may very well represent a compromise between what is desired and what is available. To assist you in obtaining the proper information required to select a proper belt construction, the following check list is…
Belt Conveyor A belt conveyor system consists of an endless belt of resilient material connected between two flat pulleys and moved by rotating one of the pulleys by electric motor. Normally material is fed on the belt near the other end pulley. The moving belt carrying the material towards the driver pulley is likely to…
