Maximum usuage of conveyor belt

Apr 10, 2017 This not only produces the most economical operating conditions, but also the maximum tension in the belt. The chart is a graphical representation of the formula : Where, p = kgW(L + 10H) p = the correct number of plies k = a constant, depending on the type of drive g = the weight in pounds per cubic foot of material handled W = the width of the belt in inches L = the length of the belt in feet

L = conveyor length (m) ε = belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note: For long-distance conveyors, dynamic start-up calculations. may be required, because not all elements are set in motion simultaneously

In the case of a simple horizontal conveyor the maximum belt tension T1 is the sum of the effective tension Te and the slack side tension T2 ie: T1 = Te + T2 T1 is the tight side tension and 12 is the slack side tension For a more complex conveyor profile that is inclined, additional tensions are induced due to the mass of the belt on the slope

Notes: As a rule of thumb, the maximum angle for conveying cardboard boxes is 25 degrees. If conveying plastic containers, 15 degrees is typically the maximum incline. The conveyor can be inclined up to 30 degrees. Use our Box Tumbling Calculator to find the maximum incline angle for your containers. You may also be interested: Incline Conveyors
