A Comparison of Effective Tension Calculation for

The difference between CEMA and DIN when determining the effective tension is on the use of coefficient of friction, because DIN uses a global coefficient of friction while CEMA uses different friction coefficients on idler, belt and material. This difference in coefficient of friction results in different ways of calculating the resistance being the accumulation of the effective tension. The result is an effective tension value using DIN

For example, the measurement from the base or the conveyor frame to the top of the center roll in a 4” diameter CEMA B is 7”, a 5” diameter B roll is 7-1/2”; the same measurement in a 5” diameter CEMA C is 8-3/4”. Individual idler replacement on a conveyor will lead to variations in the center height creating hills and valleys in the belt run, placing undue load related stress on the higher rolls as well as the potential for disturbing material on a loaded belt
