Metso recognised
Metso has been presented with an award
by Freeport-McMoRan Inc. for the long-term
partnership between both companies. “Your
long-time support of Freeport-McMoRan
has been a cornerstone of our success.
Most recently, your highly motivated team
has partnered with us as we weather the
difficult cycle that brought copper prices
to near six-year lows. Thanks to this team
effort, both our companies have worked to
reduce costs, gain efficiencies and remain
competitive. I am confident in the long-term
future of commodities and our industry. We
look forward to further strengthening our
partnership and moving ahead together,”
says Richard C Adkerson, president and
CEO of Freeport-McMoRan.
CDE’s research buy-in
CDE Global recently participated in the
first meeting of the EU-funded RE4 Project
in Brindisi, Italy. Over the next three-and-
a-half years following the first landmark
gathering on September 15, CDE shall
contribute to this group to develop new
technologies to increase the reuse and
recycling of construction and demolition
waste material in energy efficient prefab-
ricated elements for building refurbish-
ment and construction.
“To be involved in the first Horizon 2020
funded research project in this area is
an exciting prospect and a great oppor-
tunity to make significant advancements
in reducing the environmental impact of
construction and demolition activities,”
said Sean Kerr CDE representative, the
Northern Ireland firm’s head of engineer-
ing, speaking about the project.
Terex AggreScalp to boost quarries’
bottom line
Terex Washing Systems (TWS) has
launched its new Terex AggreScalp scalp-
ing unit and new Finesmaster UltraFines
recovery system, both said to boost any
quarry operation’s bottom line. The Terex
AggreScalp is a versatile, high-perfor-
mance heavy-duty electric screening ma-
chine that has the flexibility to operate as
a two-way or three-way split screener.
The aggressive screen can accept
media including bofor bars, finger screens,
woven mesh and 3D punch plates, which
allows it to be used across a wide variety
of applications. With on-board hydraulic
folding product conveyors, hydraulic
screen angle adjustment and single lift
set-up, it is easy to transport and to set
up. The AggreScalp can work in conjunc-
tion with the Terex AggreSand range by
providing a consistent feed material even
in difficult applications.

Weir Group’s investment into itsWeir Heavy
Bay Foundry (HBF) continues at pace, and is
set to position the operation as a best cost
producer of quality castings. The recent
commissioning of an advanced secondary
sand plant at Weir HBF will allow the Port
Elizabeth foundry to reduce manufacturing
costs, further enhance the quality of its
castings and mitigate the impacts of the
operation on the environment.
Grant Ramsden, operations director
at Weir Minerals Africa, says the new
sand plant deploys magnetic separation
technology to extract chromite sand
added to furan sand during the moulding
process. The plant also scrubs the resin
from the sand by a process of attrition.
The recovered furan sand can now be
reused, resulting in significant savings in
sand disposal costs, resin costs and the
purchasing of new sand. “In addition, Weir
HBF will be able to improve the efficiencies
of its casting processes by reducing ‘sand
burn-on’ caused by excess chromite sand
in the furan sand,” says Ramsden.
The secondary sand plant incorporates
German proprietary chromite separation
technology, and state-of-the-art program-
mable logic controllers. In line with lean
manufacturing principles, the plant only
runs when there is a demand for sand. It
was installed and commissioned using
Weir engineering expertise.
The lion’s share of the overall investment
has gone into improving safety and
productivity of workers at the operation.
A sound example of this is the seven new
fettling booths that have all been equipped
with dust extraction systems. “Equipped
with state-of-the-art equipment and its
strategic location close to the deep water
Port of Ngqura, there is no reason why this
operation will not be able to contribute
to Weir Minerals Africa seizing a larger
share of the niche one ton to 17 t castings
market,” says Ramsden.

Haver & Boecker, an equipment manufacturer
and solutions provider in aggregates and
mining applications, has introduced its Tyler
brand of hooked engineered screen media as
a solution to the problem of expensive deck
conversions. Tensioned screen media can be
used on a cambered deck, eliminating the
need for a deck conversion when switching
from woven wire to polyurethane screen
media. The media includes products such
as Ty-Max and Ty-Wire. “Hooked screen
media allows operations to easily switch
from woven wire to modular polyurethane
products without the expense of a deck
conversion,” the company says. Retrofitting
a machine from a cambered deck to a flat
deck can cost as much as US$15 000 per
deck. Tyler’s tensioned screen media is used
on a cambered deck to eliminate the need for
that conversion. This also allows operators
to test the media on a vibrating screen with
no additional cost or commitment.
Another benefit is that Ty-Max and
Ty-Wire can be blended with woven wire or
self-cleaning screens on cambered decks. In
many applications, operators are looking for
more wear life on the feed end of the screen.
This can be accomplished by installing a
section of Ty-Max at the feed end. Ty-Wire
can be used in the middle of the deck, for
example, where basic screening takes place
to give operators the ideal combination of
wear life and open area. Using woven wire
or self-cleaning screens at the discharge end
will provide maximum open area at the end
of the deck.
The polyurethane screen media is
manufactured out of Tyrethane, Haver &
Boecker’s signature blend of polyurethane.
Chemists developed Tyrethane to offer the
best combination of open area and wear life
for both wet and dry applications. Tyrethane
is poured open cast, resulting in 1,5 to two
times longer wear life than comparable
injection-moulded products. In addition, open
cast polyurethane permanently hardens when
cured to maintain its chemical properties, so
it resists wear and tear.
