### Conveyor Belt Equations

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, due to the elastic properties of the conveyor belt.
