A. Conveyor/Carrier Roller/ Gravity Conveyor Rollerng UHMW-PE (Ultra High Molecular Weight Polyethylene):
Ultra High Molecular Weight (UHMW) Polyethylene is often referred to as the world toughest polymer,it is a thermoplastic engineering plastic
with the average molecular weight more than 6.0 million. (PE only has the molecular weight between twenty to two hundred thousand.) which
is regarded as a surprised engineering plastic of excellent comprehensive capacity
B. Advantages for UHMW-PE Roller Idler
1.Abrasion resistance
UHMWPE has abrasion resistance 10 times that of HDPE .
2.Impact resistance
UHMWPE has the highest impact strength of any engineering plastics, about three times which of nylon, two times that of PC, five times that of ABS.
3.Effective sealing system
The primary labyrinth seal prevents most of the dust to get into the bearing house, and no water could leak in.
4.Light weight and energy saving
UHMWPE rollers are only one third less in weight than steel roller, they are even lighter than HDPE roller, since they have
superior strength .Light weight and low friction result in considerable energy saving.
5.Reduced belt damage
UHMWPE shell is self-lubricant, and prevent the adhesion of any transfer material, so no damage was caused to conveyor belt.
6.Noise reduction
UHMWPE is a much better noise debase material than other materials, UHMWPE rollers generate much less noise than conventional
steel roller, they are environmentally friendly.
7.Corrosion resistance
UHMWPE roller can withstand humidity, corrosive chemicals, acids, salt and alkalis.
8.No sticking
UHMWPE could not be sticked by any material, so no conveyor material will be sticked to roller surface.

Conveyor/Carrier Roller/ Gravity Conveyor Roller
Features of chinese Gravity Roller Conveyor aggregate circular vibrating screen
Special Conveyor/Carrier Roller/ Gravity Conveyor Roller design, more powerful exciting force and simpler maintenance.In order to satisfy the higher performance and more complex application conditions of the customers during the production operation process, Conveyor/Carrier Roller/ Gravity Conveyor Roller aggregate circular vibrating screen adopts SV super-energy vibration exciter core. This vibration exciter not only owns powerful exciting force, but also can be integrally installed in the inner hole of side plate,Gravity Roller Conveyor which avoid the trouble of replacing one bearing; the integral disassembly, assembly and replacement Conveyor/Carrier Roller/ Gravity Conveyor Roller will only take one hour, and the replacement and maintenance are very convenient.
HJHGFVDH
Gravity Roller Conveyor is of higher degree of universalization and greatly reduces the types of user’s spare parts Gravity Roller Conveyor, including screen tensioning plate, screen surface batten,Conveyor/Carrier Roller/ Gravity Conveyor Roller screen surface supporting bar, rubber liner plate and screen, all adopt standardized, modular and universalized design. Conveyor/Carrier Roller/ Gravity Conveyor Roller reduces the maintenance points of the screen and the types of user’s spare parts, thus guaranteeing the simple and practicable operation and maintenance.
