The aggregates are fed by the
dryer feed belt into the lower part of
the dryer drum in which the initial section contains
a series of spiral
flights which feed the material towards the internal
flights. The flights
have been designed in such a way as to lift the
aggregates and then
drop them in a thin veil in front of the burner
flame ensuring an
efficient drying process. The Drying unit is started
through Siemens
soft start technology, resulting in a smooth
activation process.
The burner and the drum tube form a precisely
balanced unit, the
combined effect of which is low fuel consumption,
exit height and gas
temperature and secondary air intake resulting in
the improvement
and economy of the mixing unit as a whole. |
