The elastic modulus of the conveyor belt is the ratio between the stress and strain of the belt; it is an important index for assessing the capability of the belt to resist elastic deformation. A higher elastic modulus often indicates that a greater stress is required to cause elastic defor-
The implementation of multiple drives for belt conveyors can solve the problems associated with motor overpower and the excessive tension of conveyor belts powered by a single drive. However, multiple drives can suffer from uneven driving power allocation. Among various factors, the selection of the type of conveyor belt particularly affects the power allocation. The current …
The modulus of elasticity is calculated by dividing the stress by the strain, where . M = modulus of elasticity (ISO 9856) F = force (N) ε elast = elastic elongation at the end of the specified number of cycles (N/mm). In other words: The higher the modulus the lower the elastic elongation per unit stress.

Modulus is a measure of a conveyor belt's resistance to stretching. The modulus of elasticity in tension, sometimes referred to as Young's modulus, is defined as the ratio of the increment of unit stress to increment of unit deformation within the elastic limit. A list of conveyor belt modulus is provided below.
Belt modulus is the modulus of elasticity for belt, and its purpose is the same as modulus of elasticity for other materials. For materials, it is E = (Stress) / (Strain). This mathematically translates into required stress to create extension of length equal to original length i.e. strain = 1 which is called unit strain.

In simplified terms, the load required to elongate the belt 1% is calculated by dividing the elastic modulus by 100. Because of the relationship of modulus to load (stress) and elongation (strain), the higher the modulus the lower the elastic elongation per unit stress. Example: Belt Modulus = 60,000 piw Load required to elongate belt
Typical values for conveyor belt modulus may range from 1000 piw to 100,000 piw. Determination of the value used for elastic modulus calculations has varied among manufacturers and engineers within our industry. One such method of determination that is widely used is the international standard ISO 9856.
