Re: Tube Drag Conveyor
I'm a bit confused here, are you
1) talking about a chain conveyor in a tubular housing?
2) talking about a Tube Belt Conveyor, where the conveying belt is rolled longitudinally to form a tube that contains the material ?
If its a chain conveyor in a tubular housing then a conveyed distance of 250m is too much for a single machine and machines in tandem would be needed. If you wanted to blend different grades then it would be necessary to "layer" these into the first machine at the feeding points, then as the layers of material tumbled at the junctions between successive machines a degree of mixing would take place. ■
Re: Tube Drag Conveyor
Dear all,
Terribly sorry that My english isn't good. So i made you confused. I've read the reply from you. I would like to know about Disc - Cable conveyor in Tubular Housing.
Thanks a lot for your advice.
I have some questions:
- Is it possible to integrate drying process with the conveying process?
- I have got some trouble in calculating the friction loss in the tube caused by bulk material. I fluidized the bulk material layer in the tube and calculated the loss energy like in the case of fluid with the modification factors. Is it O.K?
Best regards,

Re: Tube Drag Conveyor
You won't get a disc-on-cable mechanical conveyor to do 150 te/hr, unless someone can prove me wrong.
It is possible to dry (partially) product during conveying in mechanical conveyors, but in most cases conveyors are used to convey and driers are used to dry.
Power in mechanical conveyors is all about friction. The mass in movement, the coefficient of friction and the speed.
But you need practical experience and knowledge. In most cases this resides with those employed by companies who make mechanical conveyors (especially the more specialised types of machines). They don't give this information away, you buy their machines. ■

Tube Drag Conveyor
Dear all,
I have some problems in calculting the energy loss in conveying pipe system.
Anyone helps me? I have some questions:
1. In the case of Tube drag Conveyor, is it possible to integrate the pre - blending process with the convaying process in the same time? I have an idea of using blades on drag disc for blending, how to design the profile of those blades?
2. How to choose the diameter of tube if the pitch between two dishes is known? We have the initial known factor about material (coffee beans), Conveying quantity 150TPH, Distance of conveying:
- Total Height: 4m.
- Total Length: 250m.
Best regards to all,
