Rising demand for Bateman-APIC Jigs
Intensive global marketing of the Bateman-APIC jigging technology
has resulted in contracts for three jigging plants during 2005, two
in India and one in Europe. These jigs all incorporate the Bateman-APIC
under-bed air-pulsed jigging technology.
The APIC Jig is an efficient gravity-separation process used to clean
saleable material from waste / raw material by separating particles
of different densities in a homogenous bed of granular material.
In October 2005 a 300 t/h coarse-coal Bateman-APIC Jig was commissioned
for ACB at the Dipka Mine in Chhattisgarh State, India.
The coal washery at the mine is one of the largest in India, processing
10 million t/yr of coal using gravity-separation techniques.
The run-of-mine coal comes from the nearby Gevra-Dipka open-cast
mining complex, Asia's largest mine of this type. It produces 110,000
t of coal per day, used primarily in thermal-power stations in and
around Korba, but also in other power stations around India.
The jigging facility supplied to the Dipka site comprises a Bateman-APIC
Jig and bucket elevator which has been installed at the core of a
new expansion phase at the washery. It is the second 300 t/h APIC
Jig supplied to ACB in the past year.
The jig, designed by Bateman Engineering, was manufactured and assembled
by Delkor Technik India. Delkor India is Bateman EngineeringÕs
jigging-technology partner in India and also markets the technology
in that country. Some of the key components of the plant, mainly the
control system, were imported from South Africa. The modular nature
of the facility enabled the washery personnel to easily undertake
the assembly.
Commissioning, by a team comprising engineers from Bateman Engineering,
Mintek and Delkor India, and plant operators from the mine, took only
a few weeks.
Also in India, a mobile two-gate Bateman-APIC Jig was commissioned
earlier in 2005 by Bateman Engineering and Mintek engineers for Nava
Bharat Ferro Alloys Limited near Meramandali in Orissa.
The jig is being used for the recovery of marketable ferrochrome
from furnace slag in size fractions of minus 6 mm and plus 6 mm and
a rate of between 25 and 40 t/h. BATEMAN was able to guarantee an
optimum recovery of metal with an efficiency surpassing that of any
of its competitors.
Manufacture, pre-assembly and testing was done in South Africa before
export to India. A team of Australian, South African and Indian engineers
supervised the erection and provided training for the plant operators.
Towards the end of the year an order was received from a company
in Europe for a similar jig with a JigScan controller to facilitate
operations. It is equipped with an integral pulse control system and
will be the first such installation in Europe. It is fully compliant
with European safety and environmental regulations.
This is the second APIC Jig to be ordered by this company, where
30 t/h of ferroalloys less than 30 mm in size is produced as well
as sand for the aggregate industry.
A contract to supply APIC Jigs to process ferrous ore has also been
received recently from a client in Asia.
