Rotary kilns have been used successfully for many years to
produce calcined coke for the aluminium industry and they offer a
high level of automation, performance and flexibility. Shaft
calciners make a high bulk density, coarse particle size product
and several papers have been published recently highlighting
these benefits. This paper presents a comparison of the merits of
these two different calcining technologies from a product quality
and process performance perspective. It addresses several
misconceptions about the technologies related to operability,
product quality and their ability to handle a wide range of green
coke qualities. Both technologies will continue to be used in a
complimentary manner in the future.
