1) What rate (te/hr)

2) What material density (kg/m3)

3) How far (m)

4) Horizontal or inclined (degrees)

5) Particle size distribution

The above will enable more informed suggestions to be made. ■

Urea prills or granular ??? ■

If the product is a powder I would certainly consider an enclosed screw conveyor over a belt conveyor (even if provided with covers). ■

Could we be of any help engineering the screw conveyor part ?

Have a look at our website www.van-beek.nl ■

Dear Mr. Notis Koumakis:

Given the details you provided, I would recommend the use of a Serpentex belt conveyor system. This would allow you to load directly from the bags and discharge directly above the reactor without grinding the granules. Also, this conveyor style will provide you with good spillage control (provided you do not overload the sections).

Dear Mr. Notis Koumakis

Please provide full information about the material characteristics i.e. (1) material size, (2) material size gradation, (3) bulk density, (4) Abrasiveness, (5) Corrosiveness, (6) Susceptibility to degradation, (7) repose angle, (8) whether hygroscopic, etc. and your certain statement about the nature of this material and specific requirement in handling the material.

For example, if it is urea prills from fertiliser plant and is to be marketed then it should not get degraded. In this situation belt conveyors are regularly used running at low speed about 1.25 mps, or less. It’s loading and unloading etc. are also designed very carefully so that minimum portion of the material gets degraded. If it is this kind of material then use of screw conveyor is ruled out. But if you are referring to different physical condition of urea for some other purpose then it could be a different case. The material particular condition and purpose makes remarkable difference in suggesting the type of equipment, particularly when such materials are of special name and nature.

"We were asked by a customer of ours to offer him a fully equipped reactor (design, engineering, procurement and installation) that produces resins based on urea and melamine."

So the application USES urea, it doesn't PRODUCE it. So I'll stick with a screw conveyor over a belt conveyor. ■

In that case please sent us some details (drawing etc) info@van-beek.nl

We could provide you with IIID design if you are interested. ■
