    Conveyor Belt Ice Buildup

    I am looking for some information on any type of pulley heating system. We have ceramic inlaid pulleys in place and our consumption of deicer is expensive and I am searching for any information on ways to heat the pulley in order to prevent ice buildup.

    Not sure what you are using now but have you tried Liquid Heat. Check out the link below. Works well in Canada.

  3. Dear Mr.Trentaiken,
    I do not know about the installation of conveyor-is it outside the building or inside the building?You can use additional drive to run the conveyor at empty during non-working time which may reduce the problem of ice building.

    Heating of pulley

    Dear sir
    you can consider heating of pulley by providing heaters below shall connected thru slip rings . withthe help of rtd you can control the temperature of pully shell at about 20 degree centigrate.
    function will be similar to electromagnetic pulley in this cse instead of magnetic coil heating coil will be provided.

    Do you have one of these in operation or have information on one?

  7. Conveyor belt ice build-up

    Dear Mr. Trentaiken,
    ISPAT KARMET at KAGAKHSTHAN, they do not stop the conveyor to avoid build up of ice.They use only one drive. But I suggest you that you must use one small drive to run the conveyor during ideal time.
    Regards.

    wow
    Do not stop the conveyor waste power continously
    provide another drive for ideal running again waste power and cluch in both drive
    why all these just to remove ice
    when other economical methods are available like liqid heat, salt rock or pulley heating are available pl donot sugest in case somebody is using same.
    I also request you pl donot mind as this forum is to express your views here you are not consultant and vendor will listen to you

    Pulley Heating

    We currently use Liquid Heat but still experience ice build up from time to time.
    It is a mater of more than just running the belt, we can keep the belt running and still experience Ice Build up. We experience temperatures down to -40 degrees (F).

    There are two ideas I am pursuing.

    1. An infrared type heater that only heats up the pulley only an will shut of at an amient of "x" degrees.

    2. Or, develop a pulley that has built in stator, and rotor and heating coils that will generate its own electricity internally to heat the coils merely by it rotating and that will open the induction circuit once a temperature of "x" is reached.

    Dear Trentaiken,

    Have you looked at the operation in the Alberta Oil Sands?

    They use a special casted polymer for their lagging.

    THe Rheinbraun coal field operations use an extruded polymer that looks similar to the Oll Sands. This polymer is applied to a rotating pulley when to lagging is applied from a fixed end tube fitting.


    I can put you in contact with Syncrude's operating engineers to allow your further investigation if you have not already done so.
