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,

pipe conveyors or tubular conveyors, high incline or high angle conveyors, wheel-on-rope type of conveyors like cable conveyors and Ropecon. Pipe conveyor was first installed in 1980s in Japan, the actual advantages of using pipe conveyor was its capabiitt to accomplish sharp curves and seal the transporting material.

Typical Conveyor Capacity. 1 in = 25.4 mm. 1 ft3/h = 0.028 m3/h. 1 ft/min = 5.08 x 10-3 m/s. The product cross sectional area is defined by the idler trough shape and the product pile on top of the idler trough the trapezoid shape. This section on top of the trapezoid can be described with a circle and the angle this circle makes with the belt ...
