Oil Resistant Belt Quality

Posted in: , on 20. Sep. 2011 - 21:55

Dear experts,

In our rock phosphate floataion plant we are using Tall oil,Diesel oil and Sodium oleate to flaot and seperate the rock phosphate from the ore.

After separation the rock phosphate is conveyed through belt conveyors.

The quality of the belt is oil resistance -G but after installing the new belt,the belt is running off center and totally going out side.The belt is

in curved shape in the return side.(The problem starts after 2 months run)

To over come this problem we are oblized to stop/start the belt with product.

Existing belt Specification:

Width :800mm

Thick: 6 + 2mm

Quality:Fabric-Oil resistence grade-G

Strength: 250N/mm

Ply: 2

Kindly suggest the suitable belt quality.

With Regards,

M.Ayappan.

Dear Mr. Appayan,

those effects must not only be due to belt quality, but can also be due to the mechanical installations that support, drive and guide the belt. By your description an accurate & applicable opinion may not be formed, suggestion is that you contact the manufacturer of the conveyor itself and/or make the maintenance staff look into any handbooks and manuals and/or hire a reputed specialist who may have a look onto the issue on site. Belt tension device / misplaced idlers / belt training device in lower strand could be starting points. Concerning the belt, if in last time your staff had to re-tension the belt quite a lot, this may be due to "undue" elongation, which must be further investigated. I fear though that your present belt may not reach a much longer service life.

Best regards

R.
