Rotary kiln section

Graeme Moir, in Advanced Concrete Technology, 2003. 1.3.2 The modern rotary kiln. The rotary kilns used in the first half of the twentieth century were wet process kilns which were fed with raw mix in the form of a slurry. Moisture contents were typically 40% by mass and although the wet process enabled the raw mix to be homogenized easily, it carried a very heavy fuel penalty as the water

    Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum. Direct-fired kilns utilize direct contact between the material and

    ROTARY KILN CHAIN SYSTEMS At the cold end of the kiln, the relatively low gas temperature hampers heat transfer. To improve this, a section of chain is hung from the shell in this part of the kiln. This chain is made up of links that are typically in. by 3 in. (1.9 cm x 7.6 cm). Hangers attach lengths of this chain directly to the kiln shell

    Cement Kilns: Design features of rotary kilns

    The early commercially successful rotary kilns in Britain were nearly all straight cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were

    Rotary Kiln Shell Section Alignment Procedure

    The conventional procedure for aligning kiln shell sections prior to welding is to adjust the joints as necessary so that they are centered on the kiln rotating axis. This is accomplished by measuring and minimizing the shell radial runout at the joints, or by centering the joints on a line of sight (or laser beam) along the center of the kiln. The
