Thread: Conveying of Wheat

  1. Conveying of wheat

    We are looking for a pneumatic conveying system for wheat.

    This is a typical requirement and not usual one. The distance to be conveyed is ~ 700 mtrs and capacity 600 + TPH in 24" pipeline.

    Any ideas on this? For further details reqd., pls. contact on jigishu.shah@portofmundra.com

  2. wheat conveying

    Are you sure you want to do it pneumaticly? It will take a lot of energy. When you have a lot of bends, you will have a lot of wear.
    With closed tube type belt conveyors there is a lot possible!
    Send me a lay out drawing of the track and we can have a look at it.

    For such a long distance I would suggest you consider using a water slurry system. You will prevent attrition of wheat particles and will have a much smaller system than a 24 inch line.

  5. Mr. Agarwal,

    didn't got your point properly. How the system works? Can you please throw some more light on this.

    Thanx,

    I would not have thought it advisable to deliberately mix wheat with water, you usually want to keep it dry?

    I agree that wheat should not be mixed with water but it all depends upon how long the wheat particles remain in water. The conveying time can be as short as 20 seconds. Due to this short time, slurry conveying of wheat in water should be Ok.

    Conveying of wheat

    You still have to dewater and dry the wheat when you receive it. Seems to be a very expensive option. Even the addition of very small quantities of water (0.25%) for dust suppression purposes is prohibited by most grain handlers. Most put a limit of 12% moisture on receivals.

    All of the moisture should be surface moisture. This is normally removed by centrifugal dryers. These dryers can remove surface moisture down to 0.1%.

    Dear Mr. Shah,

    I am not sure if you have already got your solution !

    However, I am inclined to ask you

    1. why you are so specific about 24inch pipe size !
    2. is the pipe routing very complicated with lots of bends !!
    3. Since the distance is not very long, I would go for stepped piping solution and try to maintain as much dense phase as possible inside the pipeline (in order to reduce the degradation of weat particles)

    In case if you feel that we could help you through some Indian counterpart known to us I would be glad to be of assistance!

    best regards
