CATALOGUES  - Conveyor Rollers - Composite roller

Production Progress:  

Composite roller shell is made of polypropylene, Quartz sand, carbon black,  high hardness powders etc 16 kinds of materials.It is thermoformed by patented technology.

3. Low Noise factor 

 

Clients conducted a noise test on the metal roller and composite idler roller at the site of use of the conveyor CV371. At the belt speed of 6m / s, under normal working conditions,  the metal roller noise was 80db; composite Roller was 70db.

5. Anti-material sticky & Anti-static 

 

when the conveyor running, the static material were sticked on the steel roll surface, which caused corrosion the roller, wear the belt, belt deviation problem , tearing the belt, belt overloading capacity, waste motor power. Because of our composite roller is anti-static, anti- material sticky, there are no electromagnetic dust attraction, it can protect the belt and save cost.

6. Anti-corrosion anti-acid and alkali 

In tianjin coal terminal, humidity, high salinity, poor environment, the parts temperature is about 50 degree in summer.  In 2014 , they installed composite rollers, until now the composite rollers are working very well.

7. High Anti-magnetic properties 

The composite rollers were installed under the superconducting iron separator section in Tianjin coal terminal, the opration of the superconducting iron revomer reaches 30000GS. After 12 months, there was no influence on composite roller, the stainless steel roller working life is less than 6 months.
