    Flow of materials in rotary kilns used for sponge iron

    The present work identifies the basic features of burden movement in a rotary kiln. The cold model study was conducted with iron ore as the feed material to determine the influence of length to diameter ratio (L/D) of a rotary kiln on the filling degree, hold-up, and residence time of the charge. An empirical equation correlating different operating variables has been derived on the basis of

    Flow of materials in rotary kilns used for sponge iron

    The formation of accretions or ’rings’ in rotary kilns used for the manufacture of directly reduced iron (sponge iron) affects the residence time of the charge, kiln hold-up, and the kiln output to a great extent. In this part of the work, the effect of ring formation was simulated at room temperature in a scaled-down model of a rotary kiln by inserting conical dams in the shape of

    Study on Air Tubes Failure in Sponge Iron Rotary Kiln

    Keywords: Sponge Iron, Heat Transfer, Rotary Kiln . 1. Introduction . In Rotary kiln, carbon is charged from either end, in one end in the form of coal particles and in another in form of coal lumps. The coal reacts with air to form carbon monoxide which then reduces iron oxide (ore) to iron. So, in a kiln,
