Corrugated sidewalls, splicing accessories. Thanks! However, many conveyor design calculation programs ignore these areas. As belt tensions are often highest at the head pulley, belt edged stresses in these areas are also the highest in the belt. Conveyor capacity is determined by the belt speed, width and the angle of the belt - and can be expressed as Q = ρ A v (1) where Q = conveyor capacity (kg/s, lb/s) ρ = density of transported material (kg/m3, lb/ft3) A = cross-sectional area of the bulk solid on the belt (m2, ft2) v = conveyor belt velocity (m/s, ft/s) when the belt is empty.

The required take-up length is calculated as follows, where SSp= take-up length (m) 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. The surcharge angle, on the average, will be 5 degrees to 15 degrees less than the angle of repose. For pipe conveyors it is desirable to separate the Kx term into separate values for trough and return belt because the value for return Kx is much larger than for standard conveyors. F: Coefficient of friction (See. The first app to offer handy calculations where you need them, on the job site, not on a PC. Here's the logic behind the center-to-center distance formula: 2C: Multiplying the center-to-center distance by 2 accounts for the belt length on the top and bottom of the pulleys Note: The pitch created by differing pulley diameters is addressed later in the equation.
