Cement-processing systems and equipment from BATEMAN
"BATEMAN is well positioned to assist the South African cement
industry gear up for the anticipated growth in demand from the building
sector," claims Paul van de Vyver, BATEMAN General Manager, Pneumatics
and Environmental Control. "Recent forecasts reported in the
business press indicate that cement sales in the forthcoming year
are likely to continue the upwards trend of the past year."
"During the past two decades, the cement-producing industry
has purchased a wide range of BATEMAN's processing systems, equipment
and services, ranging from storage and handling of material to environmental
control systems," says van de Vyver. "Since the early 1980's,
at least 10 large and smaller projects have been successfully completed
for clients in this industry.
"For storage, blending and out loading applications, BATEMAN
markets the Bateman-Ibau multi-compartment range of silos which can
handle all types of cement. The multi-cell concept is particularly
attractive when there are space constraints. Local environmental requirements
are routinely complied with and care is taken to ensure that these
structures are architecturally pleasing. These silos can be supplied
as completed turnkey projects in which BATEMAN provides the complete
civil, mechanical and electrical design and engineers, procures, constructs
and commissions the facility.
"Several hundred of such silos have been installed worldwide.
The most recent BATEMAN cement contract has been for NPC's Simuma
Plant in Port Shepstone (see page 1 of this issue of bateman Globe),
where a project for a large cement silo and associated mill upgrade
is underway. Several other prospects are being followed up.
"Several systems are available from which the optimal way can
be selected for moving the cement products around the silo. For example,
pneumatic-conveying systems can be installed to collect and discharge
granular material from one or many points and are particularly economic
and efficient for conveying the abrasive powdered materials commonly
processed by cement producers.
"Alternatively, Bateman-Redler bucket elevators can be used
to lift the incoming cement from the loading points to the top of
the silo compartments and Bateman-Redler conveyors may be used to
transfer product between the cells. The Redler systems convey particulate
solids cleanly, gently and economically by inducing the material to
move like liquid along dust-tight casings.
"Bateman-Ibau air-slides in the cells ensure the cement is released
from the cells as required and the rate is controlled using Bateman-Ibau
flow-control gates.
"For handling hot, abrasive and sticky materials, the robust
and durable range of Bateman-Aumund materials-handling equipment,
comprising conveyors and silo-discharge systems, is recommended. Hot,
up to
1 000°C, very fine-grained clinker with high dust contents can
be moved horizontally or at angles up to 60° using this equipment.
The Bateman-Aumund silo discharge system ensures constant discharge
rates up to
1 000 t/h, depending on the conveyor capacity, and generates little
dust. More than 1 000 systems have been installed worldwide.
"Japan Pipe Conveyors are ideal for conveying products around
cement producing plants, as the conveyed material is enclosed in a
moving belt which protects the conveyed particulate product and the
environment from mutual contamination. The conveyors can also curve
horizontally and vertically and move product up inclines 50 % steeper
than conventional conveyors, enabling a single pipe conveyor to fulfill
the function of several conventional conveyors.
"BATEMAN also supplies ash-classification plants to select and
extract waste ash from coal-fired power stations and produce high-quality,
pulverised fuel ash for the extension and improvement of Portland
cement.
"To contain the dust generated during the processing of cementitious
materials, BATEMAN supplies a comprehensive range of dust-control
systems including baghouses, reverse-pulse bagfilters, high-efficiency
cyclones, reverse-pulse cartridge filters and wet static and venturi
scrubbers."
