I
t was a one of a kind project when
J.K. Cement Works started production at
its new green field plant in Fujairah at
the end of 2014. The plant is not only one
of the few worldwide that produces white
cement, this plant also produces grey cement
in one and the same production line. It is able
to switch the necessary fuels for the clinker
process – petcoke and coal dust – in next to no
time. One reason for this smooth switchover:
the fuels which fire the kiln and calciner are
dosed by pneumatical rotor weighfeeders
from German FLSmidth Pfister. Those devices
are engineered for flawless handling of
different pulverised fuels.
In the modern construction industry,
both grey and white cement find their own
application. While grey cement is cheaper
and is used as general purpose cement for
concrete etc., white cement is instead used for
decorative and aesthetic purposes. Though
both types consist of basically the same
ingredients, the quality of the raw materials
has to be considerably higher in the production
of white cement.
The heart of each cement manufacturing
process is the clinkerisation. Therefore,
at J.K. Fujairah Cement the fuel is
prepared in the fuel tower. At J.K. Fujairah
