Oural Cement Plant, Votorantim Cimentos,
Cementos Cosmos
Dal Teknik Makina has conducted an audit to
analyse the alternative fuel burning efficiencies in
the calciner. Detailed measurements have been
taken from the calciner together with the preheater
cyclones, in order to simulate the existed inefficient
fuel feeding and gas flow conditions of the calciner.
With the measurement results and data taken
from the plant, several CFD analyses have been
developed for different fuel feeding points to figure
out the placement and angle for the most efficient
fuel burning.
Guided by the CFD analysis results and detailed
engineering of DTM, the alternative fuel burning
efficiency of Oural Cement Plant has been
increased.
Toral de los Vados Cement Plant, Votorantim
Cimentos – Cementos Cosmos
Dal Teknik Makina has conducted an audit to
figure out the bottlenecks of the pyroline together
with the raw mill unit, in order for the Toral de
los Vados Cement Plant to burn alternative fuels
without decreasing its production capacity.
After evaluating the current situation of the
plant, together with the measurement results and
documents given by the plant, Dal Teknik Makina
has prepared a detailed report pointing out the
needed improvements the plant has to carry out.

from the top of the foundation up. It comprises
the complete process equipment, electrical
equipment and automation system as well as the
complete building on EPC basis.
The throughput of the Gebr. Pfeiffer mill type
MVR 2500 C-4 with its four equal-sized grinding
rollers and a table diameter of 2.5 m amounts
to 25 tph of slag powder (dry-base). The mill is
driven by an electric motor with 750 kW.
“Gebr. Pfeiffer’s core competences in grinding
technology and corresponding services are
constantly being improved and further developed.
In this instance, Gebr. Pfeiffer offers a service
agreement, starting from mechanical inspection
via process optimisation up to replacement of
main wear parts,” said Ludwig Zetterström, CEO
of Swecem AB.
