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...Know More
