  • Drag Chain Ash Conveyor For Mining Application - Poland

    price: contact company for price

    In produced by our company wet drag chain ash conveyor we

    incorporate the following solutions:

    - shaped fastening of conveyor to the chain without

    additional fixing elements - easy assembling and dismantling

    - mining coal chains - links are connected with cell


    - conveyor box of welding construction reinforced at the top

    and bottom with the hard-steel flat bars

    - drive chain wheels with teeth adapted to mesh with

    vertical links in the mining chain - wheel design allows

    disassembly without removing the drive shaft from the drag

    chain ash conveyor

    - chains wheels, stretch rolls and chain guiding rolls are

    made of steal L35GSM - chain mating surfaces are induction


    - conveyor chain tensioning is carried out by compression

    springs or hydraulic cylinders

    - top and bottom guiding rolls of chains have the same size

    - flexibility with parts exchange

    - central lubrication system

    - control of drag chain ash conveyor operation by slow

    rotation indicator.

    For drag chain ash conveyors collecting slag from boilers

    with firing grates we also provide slag spreaders and

    flexible cover (lid). Lumps of slag sliding down from crater

    of firing grate goes into rotating blades. Then, in the form

    of small pieces, they fall into the water filling drag chain

    ash conveyor bed. There they are getting cool and divide

    into smaller pieces. This solution eliminates appearing big

    explosions in drag chain ash conveyor bed. The space between

    spreader and drag chain ash conveyor bed is covered with

    special covers (lids), partially submerged in the water

    filling drag chain ash conveyor. Cover elements are

    connected to each other very tight. Thanks to their

    flexibility covers are resistant to thermal deformation and

    unexpected changes of pressure.

    The operating experience shows that the weakest elements of

    the conveyor chain are the side locks. To eliminate this

    problem we use our own solution for which we have patent no.

    334928 of the Polish Patent Office.

    Solutions used in our devices have been notified in the

    Polish Patent Office under No.:

    - P334928 universal connecting link, especially for the

    mining chain

    - P335523 slag spreader, especially for slag installation in

    power industry.
