Annual report 2009 - Siempelkamp

Especially against the background of discussions about climate and energy
effi ciency, the conveyor belt has gained new importance reviving the market for
our presses. On many continents the material transport from mines is carried out
with mining trucks. This is an expensive process especially because the empty
weight of the truck has to be hauled during each transport. For some time, the
concept of “In-Pit Crushing and Conveying” (IPCC) has been discussed within the
mining industry. This concept is dedicated to the use of mobile crushing machines
and the increased use of conveyor belts starting directly in the mine.
Another market is that of retreading truck tires. For many decades Siempelkamp
has supplied multi-daylight presses for the production of tire treads. Single and
double C-frame vulcanizing presses are characterized by an extremely even pressure
distribution, special air systems for the degassing during the press process and
quick loader and unloader devices.

Two start-ups for conveyor belt presses in Australia
and China
In 2009 we completed two projects for steel cord conveyor belt
lines with their start-up and customer acceptance. Especially
pleasant for us was that at both locations we placed a world
record.
In July 2009 Fenner Dunlop, Australia, started operating a plant
for the production of steel cord conveyor belts in Kwinana Beach,
Western Australia. With a press capacity of 25,000 t (27,558 US
tons), the plant for steel cord conveyor belts is the strongest and
most effi cient in its class!
The centerpiece of this production line, the vulcanizing press, is
the largest of its kind. It features a production width of 3,200 mm
(10.5 ft) and a length of 18,480 mm (60.6 ft).
The plant was completely manufactured and set up by Siempelkamp.
Next to the vulcanizing press with clamping and plug
device, the scope of supply also includes the cable creel, the
cable clamping and tensioning device, the compactor lorry with
pre-press, the inspection lorry, the pull-roll stand and the winder.
The second plant accepted by one of our customers also represents
a record. Siempelkamp delivered a plant of exactly the same
design as the one in Australia for the production of steel cord
conveyor belts to the Chinese company Shandong Aneng.
Further more, this plant operates the fi rst multi-piston press in
China. Shandong Aneng decided to buy Siempelkamp technology
in the course of joint ventures with Veyance Technologies and
Goodyear EP respectively and is the largest manufacturer of
conveyor belts in China.
