Applications

The Conveyor Spiral Idlers are used on the return side of the belt as belt cleaner. Spiral steel welded on the spiral roller act as a screw and pushes the build-up material on the center to the edge of the belt, return roller. Our products are widely used in thermal power generation, harbours, cement plants, metallurgy and as well as the light duty conveying devices for industries.

Advantages

1) Solid design, suitable for heavy lifting.

2) The bearing housing and steel tube are assembled and welded with a concentric automatic.

3) Cutting of the steel tube and bearing is performed with the use of a digital auto device/machine/equipment.. 

4) The bearing end is constructed to ensure that the roller shaft and bearing can be firmly connected.

5) Fabrication of the roller is effected by an auto device and 100% tested for its concentricity. 

6) Roller and supporting components/materials are manufactured to DIN/ AFNOR/ FEM/ ASTM/ CEMA standard.

7) The casing  is manufactured with highly composite, anti corrosive alloy.

8) The roller is lubricated and free from maintenance.

9) Woring life expectancy is up to 30,000 hours or more, depending on usage.

10)Vacuum sealed which has withstood anti water, salt, snuff, sandstone and dust proof experiments
