  • Iron Ore Balling Drums FEECO International Inc.

    Balling Process Overview. Iron ore fines and concentrates are fed to a mixer, along with any additives and binders. The mixer produces a homogeneous mixture. The mixture is then fed to the balling drum, which is set at a slight slope to allow gravity to assist in moving material through the unit.

    emerge from the drum they are passed through a screening process whereby balss of the correct size are drawn off and passed to an induration process ~~rc~ss et ai, 1977). Over-sized balls are similarly drawn off and reground, while balls which are too small are fed onto a conveyor belt and recycled through the drum (Fig 1).

  • Increasing throughput in balling-drum operations

    In manufacturing (avionics), Charlie implemented pull systems, work cells, and a high performance management process. Results included a reduction in process cycle time from 45 days to nine days while increasing labor productivity by 50%. Since the improvements were sustainable, the client reduced the cycle by 40% after the project ended.

The off size material may range up to 400% of the production. Normally, the length of an iron ore balling drum is two to three times its diameter and the inclination 2-5 degrees. A drum of 2.5-m diameter and 7.5-m

  • Balling Drum Design KrechOjard

    BALLING DRUM DESIGN. Krech Ojard performed a feasibility study at a northern Minnesota iron ore mine to improve their taconite balling drum design. The project involved the replacement of two existing ten foot diameter drums with two twelve foot diameter drums, reworking feed and takeaway conveyors, and replacing the existing roll screens with wider, longer roll screens.

    01/01/1978· Normally, the length of an iron ore balling drum is two to three times its diameter and the inclination 2-5 degrees. A drum of 2.5-m diameter and 7.5-m length, operating at 10.75 rpm or 40% critical speed, should produce about lo00 tons of 19-mm pellets per day. This is equivalent to a specific production rate of approximately 13 kg/min-' m-' of the drum surface area (M2). In order to prevent a buildup of moist charge on the surface, the drum
