EP belts are normally comprised of different layers and are among the mostly used types of belts. They are made up of cover rubber and carcass.
Cover rubber protects carcass from external abrasion and impact injuries. There are available in different types, depending on the application:
Carcass provides the body to a belt and bears tension. It consists of different textile materials namely Nylon and Polyester. The carcass is made of a number of plies bonded together with rubber compound.
Range of belts:
Width: conveyor belts are offered in lengths up to 2400 mm.
Tensile strength and type: Conveyor belts are offered in two types, heavy duty and extra heavy duty. Type selection depends on different factors and operating conditions like load support characteristics, impact, troughing angle, belt fatigue and etc. Belts are of tensile strength up to 3000 kN/m and up to 9 ply construction.
