Bateman-Japan Pipe Conveyor for alumina plant in
Brazil
Tecno Moageira S.A. of Brazil has ordered a Bateman-Japan Pipe Conveyor
(JPC) that is to be installed at a large alumina-production plant
in Northern Brazil.
The JPC will convey 2,500 t/h of alumina (Al2O3) from the plant to
a ship load-out station, located some distance offshore. For much
of its length over the water, the JPC will run alongside an existing
gantry carrying four conveyors. At its ends the JPC will veer off
to link up with its on- and off-loading points. The belt will be a
total length of 776 m, travelling at 2.75 m/sec, and folding into
a pipe 700 mm in diameter, making it one of the largest-diameter pipe
conveyors to be installed anywhere in the world.
The JPC was selected as the best means to increase the amount of product
being conveyed to the load-out station, as there was no additional
space in the gantry for another conveyor. Because of its ability to
curve horizontally and vertically, the JPC will not require transfer
points to enable it to follow the curved path needed to fit it into
the existing plant layout. The pipe-form of the JPC also maximises
the load-carrying capacity for very fine powders such as Al2O3
, which
has a low angle of repose.
Another, but prime reason for the choice of the JPC is its environmentally-friendly
concept, as the Al2O3 will be carried within a closed pipe that not
only protects it, but also prevents the Al2O3 from contaminating the
surrounds. Dust-suppression units will be required only at the transfer
points at both ends of the JPC, where the pipe opens up to load or
discharge the product.
The plant is one of the largest alumina-producing facilities in South
America. Strict environmental standards are enforced for which the
owner has received a number of national and international awards,
including honours for the maintenance of health, safety and the environment
as well as productivity and quality.
Bateman Engineering will supply all of the engineering-design drawings
and proprietary and specialised components from South Africa and arrange
for the supply of the JPC’s Bridgestone belt. The main components
of the JPC will be manufactured, installed and commissioned on site
by Tecno Moageira, under the supervision of engineering personnel
from Bateman Engineering.
This R27m (US$3.6m) turnkey contract was placed in January 2007. The
JPC is scheduled for delivery by the end of the year, with commissioning
due early in 2008.
Bateman Engineering has during the past 25 years installed more than
60 JPCs in Southern Africa and elsewhere, conveying products as diverse
as soda ash, clinker, fly ash, coal fines, sludge granules, diamond
concentrate, alumina and ice.
