Mining equipment specialist Osborn
has secured a R12-million export
order to Angola for robust machines
that will enable the world’s fourth
largest diamond mine to process the
more competent material that it is
now mining.
Osborn will supply the Catoca
diamond mine with a large vibrating
grizzly feeder and a jaw crusher, says
Marketing Director Martin Botha. The
mine, which is located near Saurimo
in the Lunda Sul province of Angola,
is upgrading its primary tip in order
to accommodate the harder material
being mined, he adds.
Botha notes that an interest-
ing aspect of this order is that it has
arisen through complex global coopera-
tion – between Osborn’s Russian agent, a
Russian engineering house with a design
office in Germany, South African manufac-
turer Osborn and a diamond mine in Angola.
“Osborn netted this order through our agent
in Russia, which is working with a Russian
engineering firm that also has offices in
Germany with which Osborn has worked in
the past. It is a truly international undertaking
that reflects Osborn’s widespread reputation
for delivering robust, hardworking equip-
ment,”he says.
The vibrating grizzly feeder to be supplied
Osborn secures orders for Catoca
Osborn jaw crusher for Angola’s Catoca diamond mine.
to Catoca is anOsborn gearbox driven, 3-step,
2 m x 4,6 m machine while the jaw crusher
is a 50 x 60 unit. Botha reports that both
machines have been customised for the cli-
ent, with electrical control panels included at
the mine’s request. Osborn will be supplying
the machines and commissioning them after
installation.
“A second phase of Catoca diamond
mine’s upgrade to machines designed to
process more competent material is in the
pipeline, and may offer further opportuni-
ties for Osborn in Angola,” Botha concludes.

Safety in the workplace continues to be a
prime focus, and many manufacturing oper-
ations make use of Apex welding screens to
ensure workers are protected against weld
splatter and fumes as well as from harmful
UV radiation.
The screens are available in various con-
figurations to suit a variety of individual
requirements. The most popular version has
a free-standing frame, allowing easy han-
dling and portability. The feet of the screen
are angled to allow optimum utilisation of
floor space.
These features further promote ease of
erection, making it simple to set up and
arrange the screens in different shapes
according to the specific demands of each
particular workshop.
The screens absorb, scatter and filter the
light spectrum to create a safer working
Welding screens from Apex
environment for the welder and any co-
workers and supervisors in the immediate
vicinity.
Tests for total visible light transmit-
tance have reportedly demonstrated that
conventional materials permit 78 % light
transmittance while Apex material allowed
only 15,5 % – a dramatic difference, says the
company, particularly when one considers
long term exposure of workers and the con-
sequent repercussions on their eyesight and
even their skin.
Another important design characteristic
of the Apex welding screen is the patented
Balledge® design on individual strips, which
facilitates easy access for both person-
nel and equipment to cordoned-off areas.
Strips are made from specially formulated
PVC material and are impervious to burning.
