Modern rotary kilns

Aug 24, 2021

Thanks to the use of modern precalcination processes, rotary kilns nowadays seldom need a length to diameter ratio above 15:1. Up to this L/D ratio, Polysius offers both the classical 3-support kiln and the modern POLRO two support kiln. For the first time, rotary kiln dimensioning can therefore concentrate on suiting the characteristics of

    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 present had to be driven off in the kiln
