    rotary kilns: frequently asked questions (faqs)

    Rotary kilns are a large, rotating drum that can be either of the direct or indirect configuration. In the direct configuration, the kiln can be designed for either co-current (parallel) or counter-current air flow. As solids pass through the drum, the heating medium increases their temperature

    Uranium content is concentrated at the base of the MCB and decreases moving toward the top of the bed. The MCB ranges from 1.3 to 4.4 metres in thickness. The floater reefs are generally thinner, ranging from 0.1 to 2.0 metres in thickness, and generally contain uranium grades of less than 0.04%

    In the dry method, UF6 is heated to a vapour and introduced into a two stage reaction vessel (eg, rotary kiln) where it is first mixed with steam to produce solid uranyl fluoride (UO2 F 2) – this powder moves through the vessel to be reacted with H 2 (diluted in steam) which removes the fluoride and chemically reduces the uranium to a pure microcrystalline UO2 product

    Rotary Kilns. Industrial Rotary Kilns are primarily used in cement, lime, and iron ore processing. These furnaces use direct flame-fired heating methods to remove volatile compounds, instigate chemical reactions, and fuse powder into pellets. The material is rotated as it moves through the kiln, in order to evenly heat said material without
