How to determine the speed of the conveyor belt

Author:admin　Source:Original　Updated:2013-9-29

Selection of conveyor belt speed depends largely on the nature of the material being transported , the required transmission capacity and the use of the belt tension .

Powder material should be as low as possible under the conveying speed in order to reduce dust, particularly at the feed and unloading should be so . Brittle materials should also limit the speed of conveyor , conveyor belt and is transported as fragile material in the roller on the beat , so need a low belt speed so that the feed point and the discharge point does not entail fragmentation of brittle materials .

Heavy and sharp edges of the material to be transported at moderate speeds , because the material may become excessively sharp edges of the cover layer belt wear , especially when the material along the belt running direction is significantly lower than the charge speed of conveyor speed This is especially true .

For the selection of belt speed should consider the following factors :

( 1 ) Bandwidth: belt width is smaller, high-speed operation , the more unstable and prone to serious or even sprinkle material phenomenon .

( 2 ) fixed belt conveyor , installation quality are generally higher , preferably higher belt speed ; semi- fixed and mobile conveyor speed should be low.

( 3 ) horizontal or nearly horizontal transport speed is high, inclined conveyor , the greater the angle , the material more easily scroll or inclined belt conveyor safety Pei . In contrast, the material more rolling or sliding on a conveyor belt .

( 4 ) The larger transmission capacity tonne-kilometers , the required conveyor intensity.

( 5 ) the impact of loading and material impact will cause belt wear , so the best short-distance conveyor slowed . However, to reduce the belt tension , long distance conveyor often used high speed.

In summary, can be used in the case of high belt speed : long-distance transport ; material block is smaller than the maximum allowable block degree ; material mixed with a certain proportion of the different sizes of the powder , i.e., low percentage of large pieces of material ; rational design belt loading point , the material can fall smoothly and reduce tension on the belt when ;

Belt has sufficient impact strength and toughness to withstand higher belt speed ; conveyor systems operate independently , once a week or operation will last one day ; high quality and comprehensive repair and maintenance systems . Installation costs which is a major consideration.

Hand, can use a low belt speed situations: the number of short conveyors conveyor system ; containing large degree of hardness and bulk material ; material powder has less ; loading points use of conventional design ;

The use of ordinary strength, hardness and restorative conveyor ; belt speed is limited by the quality of roller and conveyor ; conveyor system run convergence ; ordinary maintenance quality.
