CRUSHING/SCREENING
‘train’
makes its African debut
The 694+ dual power
inclined screen delivering
four products.
The dual powered
J-1175 jaw crusher
incor-
porates the robust JW42 high performance
electrically driven single toggle jaw chamber
and a heavy duty VGF feeder to give optimum
production. Additional benefits are said to
include rapid set up time, ease of maintenance,
high reduction ratio, high output capacity and
an advanced electronic control system.
The jaw chamber is hydrostatically driven
which offers operators reversible operation for
clearing blockages that may be experienced in
demolition and recycling applications.
The hydrostatic system also provides vari-
able chamber speed to suit given applications.
Chamber CSS (Closed Side Setting) adjustment
is fully hydraulic and can be changed in a mat-
ter of minutes.
The dual powered
C-1540 cone crusher
incorporates the proven Terex
®
1000 cone
crusher with direct electric drive, automatic
tramp relief and hydraulic closed side setting
(CSS) adjustment. The C-1540 can be fitted
with an optional patented pre-screen module
which allows fines materials to bypass prior to
being fed to the crushing chamber offering bet-
ter wear rates in the crushing chamber.
The large hopper/feeder has an automated
metal detection and purge system to protect the
cone and reduce downtime by removing metal
contaminants via the purge chute.
The
694+ dual power inclined screen
uses
as standard two 37 kW IE2 electric motors
which operate at 50 Hz; however, a 60 Hz and/
or IE3 set-up can be configured to suit particu-
lar regions.
The intuitive and user friendly electrical and
hydraulic system allows the customer to switch
between diesel and electric mode at the flick of
a switch. The primary operation and controls of
the machine remain the same regardless of the
selected power.
The unit features a large 6,1 m x 1,525 m
triple deck inclined screen giving a total screen-
ing area of 28 m² to provide efficient screening
and high capacity.
Among the customers at the launch was
Kinyua Gachoki, owner of Umhlali quarry in
KwaZulu-Natal. “I love the idea of dual power,
especially in our current South African con-
text,” he said. “I will definitely look to buy
one of these units when replacing my current
Finlay cone crusher in the near future.”
His view was echoed by Johann van Heerden
of Sand Van Heerden in the Free State gold-
field. “With the price of diesel being what it
is, the option to run the machines on electric-
ity is bound to lower our production costs, and
a lower cost per tonne is what any machine
owner should be aiming at.”
Looking at the outlook for the dual pow-
ered concept, Terry Gillham, Bell Equipment’s
Director, Sales & Marketing, said that Bell was
expecting to see good demand for the new mod-
els. “We may be the ‘new kids on the block’
as far as screens and crushers go but – in the
two years or so that we’ve been in alliance with
Finlay – we’ve sold 60 units – 48 screens and
12 crushers. This probably makes us the domi-
nant player in the field. We anticipate that this
success will continue with the dual powered
machines.”
