Osborn exports to Kazakhstan
South African mining equipment special-
ist Osborn has secured an export order to
Kazakhstan, for an Osborn mineral sizer
that will be employed by Kazakhaltyn
Mining-Metallurgical Concern (MMC) in
its kimberlite mining operation.
According to marketing director
Martin Botha, the order is a significant
one as it is the first Osborn mineral sizer to
be exported to Kazakhstan.“It reflects our
growing success in the region, where we
already have numerous Osborn machines
in operation.”
Kazakhaltyn MMC currently has jaw
crushers in operation at its kimberlite
mine, but is replacing these with the new
Osborn mineral sizer, which is ideally
suited to the wet, claylike material being
processed.
“In winter, which is very wet in this
region, the jaw crushers are inefficient.
They are unable to crush the muddy run of
mine material, and production has come
to a standstill as a result. Kazakhaltyn
decided to replace the jaw crushers with
a different machine, and identified the
Osborn mineral sizer as the perfect pri-
mary crusher for this material and these
conditions,” he says.
Osborn’s range of mineral sizers
boast a design that can be configured to
a range of twin shaft sizers. They have a
heavy-duty low profile design capable of
handling high tonnages. “The low profile
and small footprint of these machines
makes them ideal for primary tips where
the mine doesn't want a huge installation
as is required by a big gyratory or jaw
crusher,” Botha expands.
The Osborn mineral sizer can be con-
figured to operate in two ways, depend-
ing on the material output size required.
“As a primary crusher, for example, as
at Kazakhaltyn, rotation of the breaker
shafts will be towards the centre of the
machine, but by reversing the rotation
of the breaker shafts towards the sides of
the machine and changing the tooth or
segment configuration, it can be used as
a secondary or tertiary crusher.”
The company will ship Kazakhaltyn
MMC’s new mineral sizer in two pieces,
and Osborn technicians will be on site
to handle the assembly, installation and
commissioning of the machine.

most of the dynamic loads within the framework of the machine,
which means much lighter foundations and much lower
installation costs compared to a conventional crusher system.
