HDPE rollers,Conveyor drums pulleys,Belt conveyor roller for Mine/Port/Cement/Concrete/Power Plant
Advantages and Benefits:
1, Lower weight-50% lighter than steel roller which means lower power consumption
2, Easier to install and maintenance, Easier /cheaper transportation.
3, The most important is that it reduces the cost of conveyor roller.
4, Lower abrasion and corrosion of roller shell which means longer life of roller and lower maintenance.
5, High resistance to chemical agents which means the roller will not rust and is suitable for a wide variety of applications.Belt friendly since HDPE shell will not wear and cut the belt.
6, Low noise emission due to thermoplastic noise absorption.
7, Self -cleaning roller surface which means prevention of build up of material which main cause of belt mis-tracking and less spillage from the belt.
8, Low running resistance sealing system which means lower motor torque need in conveyor start , lower power size and energy consumption.
