This is a very special application of belt conveyors. Not many suppliers for this type, and not much practical experience.

I understand you want a belt 1000 wide, with cleats every 252 mm. ***1000mm wide and 252mm is I suggest for our customer?I am not sure it is appropraite?

Question 1 - is the 160 mm side-wall part of the belt rubber, or is it the depth of the air-box underneath?***Side-wall high is 160mm

Question 2 - is the angle of the conveyor 80 deg to horizontal - that is almost like a bucket elevator?***I am sure not bucket elevator, as we always manufacture some 90 deg sidewall conveyor belt in China and for EU market.

Question 3 - how high are the cleats?

IS 100 MM IS THE MAXIMUM SIZE OF COAL TO BE CONVEY.

PLEASE TELL US % OF FINES AND METHOD OF LOADING /UNLOADING.

IF YOU WANT TO BUY BELT ,THERE ARE FEW MANUFACTURER IN INDIA WHICH CAN DESIGN THE SAME.

PLEASE NOTE FLEXOWALL GERMANY ARE SUPPLING SIDEWALL CONVEYOR BELTING.

IF YOU WANT TO BUY COMPLETE CONVEYOR ,WE CAN SUPPLYTHE SAME.

This application sounds unusual & refers to an ill-founded process flow sheet which has been used as the basis for a poor plant layout. Conveying 100mm lumps of coal, HOW HIGH?, up an 80 degree incline suggests that the coal breaker is in the wrong place. Few modern processes accept lumps that size. Conveying those lumps on any belt at those sort of inclinations is highly dangerous. Lump size needs to be reduced first. Then with a bit of attention to the plant layout you can fit a bucket elevator into the line to handle 80tph. It's not a lot is it? If you insist on using a pocket belt you have to think about running it vertical. Why: because the tension is about the same as at 80 degrees but the sag support requirement is a whole lot less, nil even.

Sidewall belts are loaded before the steep incline, in cases like these. If a large lump rolls out just after the bottom bend rollers it will fall into one of the following pockets that is approaching the rollers. That will overload the receiving pocket so that the lump will fall straight out again.

On loading, imagine that you are trying to shoot a 100mm lump into a space 252mm long & 160mm high travelling by at 1.25m/s & reasonably expecting it to stay in those confines after they have been squeezed round the bottom rollers & quickly opened up again. Let's not even consider direct sidewall disturbances.

I really recommend more time at the drawing board.
