    Small Coke Briquetting Machine In Ethiopia

    Given the significant impact a rotary kiln burner has on the costs and revenues of iron ore pelletizing, that burner had better do its job well. The capital cost of combustion equipment is negligible in comparison to the capital cost of the plant. Yet, combustion performance is a major determinant of the pellet quality and

    Aug 04, 2015 Roasting of iron ore pellets is realized in rotary kiln with kiln end connected to PH and kiln head connected to C1. Fuels including pulverized coal and natural gas are injected into the kiln through nozzle and burner-blower to supply heat for the whole system. To optimize energy consumption, off-gas from C1 is re-circulated to rotary kiln, and ...

    The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects. It has its roots in a FORTRAN program that was developed by Venkateswaran (1978) to study the reduction of iron ore. The original software was used to model the operation of a 35 m pilot kiln at the Stellco company

    The final induration is accomplished in a rotary kiln, wherein the principal heat transfer mechanism is radiation from the system's main burner. Features. There are two main processes for producing iron ore pellets: The Grate-Kiln system and the straight grate system. In the straight grate system, a continuous parade of grate cars moves at the same speed though the drying, induration and cooling zones.
