Four Belt Conveyor Layout Principles

Conveyor belt is a widely used transport equipment , transport it to achieve a continuous process , with transport capacity, strong climbing performance, simple operation , safe and reliable, high degree of automation , easy maintenance and overhaul equipment and so on. Belt conveyor can be used for horizontal transport , inclined conveyor and transported upward tilt down , arranged the following four principles .
( A ) the belt conveyor is arranged on the profile as a straight line , to avoid excessive convex arc or arc arrangement of the furrow , in order to facilitate proper operation. When the conveyor belt through a convex arcs , edges to limit elongation does not exceed the allowable value , the provisions of convex arcs curve radius R1 common belt conveyor ≥ 18B, mm (B is the tape width ) , while steel cord conveyor convex arcs curve radius R1 ≥ (75 ~ 85) B, mm. When the conveyor belt through a concave arc , in order to prevent from the roller conveyor , conveyor requirements must be greater than the weight of the conveyor belt tension concave arc upward component .
( 2 ) drives should be arranged in the unloading end , to facilitate the reduction of the maximum tension the belt . The tensioning device should generally be arranged in the smallest of the belt tension .
( 3 ) Double drum drive , in order to improve the life of the belt and do not reduce the friction coefficient between the belt and the roller surface without "S" -shaped arrangement .
( 4 ) Multi- drum -driven power allocation ratio should be used , such as driving power unit method. On the drive roller conveyor confining corners should meet the requirements of the circumferential force distribution method , such as the drive power unit , and to consider the possibility of the arrangement .
Steel cord conveyor rapid development in recent years has gradually promote the use of various types of mines . To improve transport capacity, used to increase the bandwidth and increases roller groove...
