Polyester EP Conveyor Belt

Polyester conveyor belt, also known as EP conveyor belt, wear-resistant conveyor belt, automatic conveyor belt, cement conveyor belt, high modulus, low elongation, good heat resistance, impact resistance, suitable for medium and long distance, High-density, conveying materials at high speeds. Used in coal, mining, port, metallurgy, electric power, chemical and other fields to transport materials. According to the different properties of the cover rubber, it is divided into cold-resistant type, acid-resistant type, alkali-resistant type, oil-resistant type and wear-resistant type.

Conveyor belt joint cutting length formula calculation:

L=L+(n-1)S+1/2B (single)

L=M[ L +(n-1)S]+1/2B (multiple)

Inner circumference of inner-annular conveyor belt (m)

B — conveyor belt width (m)

n — the number of layers

s — length of each layer of cloth (m)

M — number of conveyor belts
