For the Jänschwalde project,
which comprised a new
10-km-long belt conveyor
system and the retrofitting of a
bucket-wheel excavator and a
spreader (involving ABB, BEA,
and other companies), Siemens
assumed overall responsibility
for the electrical equipment.
Moreover, Siemens designed,
supplied, installed, commissioned,
and tested the conveying
system with six drive stations and
large, dynamically-controlled
conveyor drive systems, in addition to a variety of secondary
equipment.
Thanks to advanced technology,
these systems help to make both
the retrofitted and new conveying
systems exemplary in terms of economic
operation and environmental
compatability. Dynamically-
controlled drives save energy in
operation while reducing wear on
the conveyor pulleys and keeping
operating noise to a minimum.
The new control system has also
been responsible for more effective
loading of bulk material on the
belt, leading to higher overall productivity.
And sophisticated diagnostics
systems support the determination
of optimization potential
and in maintenance.
LAUBAG can be proud of the
fact that it is now equipped to run
one of the world’s most modern
opencast mining operations at
Jänschwalde.
