thyssenkrupp will supply a 4 700m-long, 1 830mm-wide overland conveyor featuring dual 5.5MW gearless
drives operating at a design tonnage of nearly 11 000 tons per hour at the Las Bambas mine in Peru.
One of the world’s largest copper reserves
will soon be accessed with the help of
high-capacity overland conveyors from
thyssenkrupp. The Industrial Solutions
business area recently won a contract to
supply a material handling system for Anglo
American’s new Quellaveco copper mine in
the Moquegua region of Peru.
thyssenkrupp will supply a 4 700m-long,
1 830mm-wide overland conveyor featuring
dual 5.5MW gearless drives operating at a
design tonnage of nearly 11 000 tons per
hour. The scope of supply also includes
the complete material handling system for
the concentration plant, including eight
in-plant conveyors and 11 belt feeders. First
production from the new mine is expected
in 2022.
Due to their proven track record of
high reliability and efficient use of energy,
gearless drives were selected to power the
new overland conveyor. The elimination of
a whole series of mechanical and electrical
components increases the reliability and
improves the efficiency of the overall system
by three to four per cent. The maintenance
requirements of gearless drives are also
substantially lower compared to other drive
systems.
According to Torsten Gerlach, CEO of
the Mining Technologies business unit at
thyssenkrupp, it is the seventh overland
conveyor project using gearless drives that has
been awarded to the company and its partner
Siemens since 2010.
The new conveyor system will initially
move 127 500 tons of primary crushed ore
per day from the pit to the stockpile adjacent
to the copper concentrator. Quellaveco
contains approximately 7.5 million tons of
copper in ore reserves — enough to wire
80 million homes or to equip 90 million
electric vehicles. Vast sections of the overland
conveyor will traverse from one valley to
another through a 3.2km-long tunnel.
After exiting the tunnel, the conveyor will
pass over hilly terrain before terminating
at the stockpile. The stacker will feature a
structure designed to replace the discharge
pulley without the need to clear out the
stockpile for crane access. thyssenkrupp
has designed similar systems for both the
Antapaccay and Las Bambas mines in Peru.

The Grib Mine, located in Russia’s
Mezensky District in the Arkhangelsk
Oblast, is one of the largest diamond
deposits in the world. During winter,
temperatures can reach −25°C
(sometimes even up to −37°C). The
Arhangelskgeolrazvedka exploration crew
bores wells and monitors underground water
levels and temperature. Keller, represented in
South Africa by Instrotech, has equipped the
wells with water-level monitoring systems.
