    Lightbulb Troubleshootin of Dust extraction equipment in a Nitrophosphate Fertilizer Plant

    We are having trouble with the operation of the Dust extraction system in our Fertilizer plant, which uses the nitrophosphate process. The system comprises a collection piping, a cyclone, a ventury scrubber and a fan (induce air flow throughout the system). Main problems are:
    1) excesive quantity of dust to be collected at 2 chain crusher to belt conveyor tranfer points. It is very difficult to handle such a huge quantity of dust.
    2) Dust material (fertilizer) is very hydroscopic which tends to plug gradually the pipes and the cyclone. Although the system is heated by hot air injection, It is very difffucult to avoid plugging.
    3) The rotary valve for the discharge of material ant the cyclone doesnot work properly.

    Does anybody can provide us with some ideas to overcome the above mentioned problems. Does anybody has experience in this particular aplication.

    Best regards,
