MODERN MINING
March 2017
Osborn reports that a R27-million order
for a turnkey crushing and screening plant
for a new mine in KwaZulu-Natal reflects
its ability to deliver customised solutions
that are a perfect match to customers’
requirements.
According to Product Sales Manager
Shane Beattie, this new plant features a
unique process designed by Osborn to
minimise fines generation in the produc-
tion of calcite and lime. It has been supplied
by Osborn to Umzimkhulu Industrial
Holdings’ Rossmin opencast limestone
mining operation at Port Shepstone.
“The plant was designed and installed
to only produce two sized products:
80 mm +30 mm and -30 mm + 10 mm. The
-10 mm is a by-product,” Beattie explains.
He says the process is revolutionary in
that a conventional crushing plant would

be a jaw and cone configuration to crush
down to a -80 mm product from a run of
mine (ROM) of 600 mm. “We supplied an
Osborn modular 3042 jaw plant feeding
into an Osborn modular 2340 jaw plant,
then over an Osborn modular 6 x 20 triple
deck screen, splitting the product into
-80 mm +30 mm, -30 mm +10 mm and a
-10 mm +0 mm.
“The primary reason for the two-stage
jaw crushing process is to minimise the
generation of fines (-10 mm),”Beattie elab-
orates, adding that this material is a waste
product.
Beattie says that Osborn’s pioneering
process is more effective than the conven-
tional separation process at other plants,
where all the ROM material is crushed to
-1 mm and smaller, with flotation then
being used to remove the impurities. “This
process requires lots of water and waste
that is more difficult to manage,” he says.
Umzimkhulu and Rossmin will only pro-
cess the high grade material, up to 99 %
calcite. By only feeding the high grade
-80 mm+30 mm to the tertiary/quaternary
plant and, with the next stage being dry,
the plant will produce a higher yield per
ton crushed. “Since this stage is the most
expensive part of the process, by only
crushing the desired calcite, the operation
will be able to dramatically reduce its cost
per ton, and the capacity in this stage is uti-
lised to its fullest potential.”
Beattie says that Osborn’s attention to
detail and commitment to meeting the
client’s needs, together with the compa-
ny’s long-standing reputation for quality
machines and service, led to this signifi-
cant order from Rossmin.
