Pipe Conveyor Belt Selection

Posted in: , on 12. Mar. 2014 - 02:54

we would like use Pipe Conveyor for transporting Calcined Petroleum Coke at material temp of 90 degree C. the belt width is 2200mm (Pipe dia 600mm) and length 1.2km.

As per our client requirement belt cover shall be 7mm on top and 5mm on bottom.

but our vendor is proposing belt cover 5mm on top and 3mm on bottom. Vendor explained that the for Pipe Conveyor System is the most critical aspect in terms of minimizing the operational problems. An under-designed belt may cause belt deformation while an over-designed belt can lead to excessive power consumption and damage to both belt and system. a too much thick cover could be damaged easier due the continuous open/close of the pipe (cover thicker more distance of external fibers from belt neutral axle higher tension on external fibers due to the belt transversal bending for open/close operation) and in addition to that, a thicker cover will determine an higher power consumption

I would like to know your opinion on Pipe Conveyor Belt Selection. is it acceptable (Vendor proposal) and does it affect belt life & operation??

Please advice.. Thank you in advance..

Hi, assuming that you shared all the critical information with the vendor (belt speed!, layout, charging situation!), and that the vendor knows the difference between a standard conveyor belt and a pipe conveyor belt I would tend to trust the belt supplier. However, for a Pipe Conveyor this size to be reasonable I am assuming that your conveying speed is very high, and together with this large diameter 5+3 sounds rather too little than too much. But again, make sure first the belt supplier knows all your critical details. Hope that helps.

First, do you know what the 90 C degree temperature will do to your belt design?

Second, you have not shared the belt construction, which is germain to the discussion. Share the belt construction, then maybe your answer will follow.

Third, have you ever designed a pipe belt of this size before or know of a successful one with the features of your design? If so, you have your anwer.

Fourth, you must know the belt's fabric and rubber properties that will function at this temperature ans stress and that will provide years of life. Do you know what properties you need? Do you know what will happen if you get these facts wrong? Can you calculate the stresses and deformation?

Based on your question, I have doubts. You can always ask for help, if you are tasked to solve the problem, but, know you know not vs. know not you know not-- recall Arab Proverb.
