A.Composite idler roller 

Composite roller material

The roller body and bearing housing are hot pressed through proprietary technology, mixed with polypropylene,

Quartz sand, high hardness powders etc total 16 kinds raw materials according to special formulation.

Advantages 

1.   T.I.R ≤ 0.1mm      

                                                                 Double end boring machine

          How do we do        

                                                          

  • Roller and bearing housing are by special double end boring machining. 

  • The machine adopts double cutter, double system control, single knife adjustment, a clamping and cutting independent ends. 

  • Non tolerance tight fit assembly of roller body and bearinghousing, processing concentricity is less than 0.02mm.


           Why we do that


  •   Small T.I.R, small vibration, conveyor runs smoothly and easily.Low power consumption and Long service life.


2. Low Noise Factor

2.png3.pngClients 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.

3.Super wear resistant

 

84pcs 152*333mm carry composite rollers and 32pcs 127*506 composite return rollers were installed in Conveyor CV371, on June, 2015.  The speed for this conveyor is 6.0 m/s. After half year,  all rollers shell wearing were < 0.2mm. 


4.Anti-material sticky & Anti-static

                                          Composite roller                                                      Steel roller

When the conveyor system which installed steel rollers running, some of the dust will often be attached to the surface of the rollers, not only corrosion rollers, and with the uneven thickness of dust, resulting in faster wear belt, deviation , Tearing and belt machine load increase and so on. As the composite rollers will not occur on the roll surface dust adhesion, effectively protect the conveyor belt, extending the life of the conveyor belt.


No sparks, More safe. 


5.Anti-corrosion anti-acid and alkali

Especially for high humidity, high pH and strong corrosiveness harsh environment, such as chemical industry and wharf.

Tianjin Nanjiang coal terminal, humidity, high salinity, poor environment, the work piece temperature is about 50℃ in summer, steel rollers service life is less than half a year. 


In 2014, we installed 200pcs 133 * 315mm carrying composite rollers, 80 pcs 133 * 950mm return 

composite rollers. It is intact so far (December 2016) 


6.High Anti-magnetic properties

        8.png

  • In 2010, a loading conveyor belt of Tianjin Nanjiang Coal Terminal was installed composite conveyor rollers in the superconducting iron separator section. 

  • The operation of the superconducting iron remover reaches 30,000GS, which has little effect on the operation of the composite rollers. 

  • They are running well until now, the replacement rate is less than 1%. 

  • Compared with the 6 months of stainless steel magnet roller working life, composite rollers can reduce cost 6 - 8 times.
