Thanks to the innovative use of Metso
Mobile crushing and screening units,
South African crushing contractor B&E
International has set up a production train
that consistently produces G1 road stone
product at a rate in excess of 550 t/hour.
Incorporating the first Metso Lokotrack
330D combination cone crusher and the
11 m² triple deck screen to be put into action
on the continent, this is regarded as one of
the first mobile trains in the region to achieve
these volumes.
“The train consists of four Metso prod-
ucts: 700 mm dolerite feed material is first
processed by an LT120 jaw crusher and is
then fed into a Lokotrack 300GPS sec-
ondary cone crusher which is capable of
accepting material up to 320 mm in size.
This in turn feeds the Lokotrack LT330D
combination cone crusher and triple deck
screen before quaternary crushing is com-
pleted in an existing Metso 9100 vertical
shaft impact crusher,” explains Sandro
Scherf, CEO of Pilot Crushtec Internation-
al, the sole southern African distributor
for Metso Mobile aggregates products
and services.
He adds that the cone crushers play com-
plementary roles in obtaining production
volumes of this magnitude. The Lokotrack
300GPS is capable of a huge output and
key to the success of the train as a whole
is the LT330D combination product’s ability
to process, screen and recirculate massive
volumes of secondary material.
According to Scherf, both of the cone
crushers were specially purchased by B&E
to produce high volumes of aggregate. B&E,
which is expected to achieve a turnover of
R1 billion in 2016, is an experienced user of
Metso Mobile products, operating a fleet of
more than 40 Metso units.

MULTOTEC GV CYCLONE
THE ANSWER FOR TAILINGS
DAMS
New MDS M412 for low capacity requirements
Tailings dams are sensitive to operating
costs, and while these operations require
quality process equipment, there is a definite
need for equipment with a low mass capable
of functioning at the required capacity and
that will be cost-effective over the life span
of the installation.
Designed specifically for tailings dam
applications, the Multotec GV Cyclone is
engineered to ensure sound operational
performance while keeping the cost of
individual components as low as possible.
RichardHaydon, processmanager atMultotec
Process Equipment, says it is important that
this has been achieved without affecting the
structural integrity or quality of the locally
developed and manufactured cyclone.
“When it comes to cyclone operation on a
tailings dam, it is critical to ensure that the
right volumetric split between the overflow
and underflow is achieved to match the re-
quired tailings dam rate of rise,” explains
Haydon.
Available in different configurations to
suit varying application and commodity
requirements, Haydon says it is the ability
to interchange the spigot and vortex finder
on the Multotec GV Cyclone that enables a
fit-for-purpose product installation. Optimum
flexibility is possible due to the different
spigot sizes and vortex finder sizes that are
available. By altering the combination of
the spigot and vortex finder, it is possible to
meet the specific operational parameters.
Selection of the size of either component is
dependent on the material characteristics,
and the tailings dam requirements.
Each cyclone is designed for an individual
application which ensures that the feed
parameters are matched to the cyclone
capacity and by doing so the lifespan of the
cyclone is optimised. “Where an application
is that specific, Multotec will collaborate with
the customer to find a unique and appropriate
solution, and this hybrid solution will take all
factors into account,” says Haydon. This will
include materials of construction specific to
the application, assuring the customer the
best possible wear life.

Metso Lokotrack LT300GP mobile cone crusher and LT120 mobile
jaw crusher are being used in a train of four Metso machines.
The recently
launched M412
trommel is ideal for
smaller production
requirements in
mineral processing
and recycling
applications.
BLT has launched the new M412 trom-
mel, said to offer cost-effective solutions
for smaller production requirements in
mineral processing and recycling appli-
cations.
“This lightweight machine, with a
compact design, is able to efficiently
handle various materials, from compost
recycling to blasted rock,” says Ken
Mouritzen, managing director, BLT
(Africa and Indian Ocean Islands). “M412
trommels have interchangeable screens
for different size rocks – between
10 mm and 500 mm – and are capable of
producing four products concurrently, at
an output rate of 150 t/hour.”
The machines are available as static
units or on tracks, depending on customer
preference. Other features include the
hydraulic push feeder mechanism, an
electric/hydraulic power system and easy
to operate control panel. The trommels
can be used with conveyors and are
also fitted with a washing system as an
option. The M412 trommels weigh in at
18 t and have a 1,25 m drum diameter
and 4,5 m drum length, making them easy
to be transported in a container.
Other machines in the MDS trommel
range include mobile and semi-mobile
units, as well as heavy duty static
machines for maximum output. Also in
the range are static and tracked trommels
for light and heavy duty recycling. MDS
trommels and apron feeders, which are
available from BLT on a purchase or
rental basis, are supported by strong
technical advisory and maintenance
service throughout Africa and the Indian
Ocean Islands.
