Thread: Belt Cleaner Selection

  1. Belt Cleaner Selection

    Dears,

    what is the best type of belt cleaner to clean fine or dust of iron ore from belt conveyor in heavy application?

    If there is any belt cleaner it should be ahead of the pulley and in any case it isn't working so well for the duty. Whatever secondary cleaner you choose, they are legion, is going to be subjective. Your goal is one of collection and transport for the debris. My underlying question is how far away is the crusher and why? Surely if there is that much debris from the crusher there ought to be dust extraction at the crusher exit. If there is a large distance then you really need another dust extraction plant because combining the airstreams would not balance. So, you need a hood to collect the dust and direct it to a screw, scooby-doo, for onward feed. The presence of a hood which almost encloses the belt then limits your choice because of the maintenance access requirement and that requirement will be very, very frequent. This will be the main factor in your selection process. Discard any cleaner which might jeopordise the regular adjustment and replacement. Remember that you will only notice wear when the belt is running ore and so if you want a cleaner operation you must minimise the adjustment time. Auto adjustment helps here and is a major consideration...if it is proved reliable. Also you need to design the hood so that various cleaners can be fitted and observed. It is very rare to get it right first time.

  3. Dear John,

    thanks for your explanation.
    yes, of course the belt cleaner should be installed ahead of head pulley. I have attached the photo(in first post) to show how dust which is not cleaned from belt, will become airborne when the belt pass through snub pulley and/or return idlers.

    So if the belt cleaned before leaving head casing, dust emission will be reduced significantly.

    What is your idea about motorized brush cleaner for this application? is it better or tungsten blade cleaner?
