CRUSHING
& SCREENING
Power comes from either a Tier 3/Stage
IIIA Cat C9 diesel developing 261 kW (350
hp) or a Tier 4/Stage IIIB Scania DC9 70A
developing 257 kW (345 hp).
The hydrostatic transmission of the jaw
chamber provides reversible operation in
the event of a blockage, as well as variable
chamber speed to allow the crusher to
be tailored for the application.
It also features hydraulic assist
Chamber Closed Side Setting (CSS)
adjustment and can be changed
in just a few minutes, says Finlay.
The J-1170 is fitted with a variable
speed vibrating grizzly feeder with
an integrated pre-screen that provides
an aggressive action to separate fines
material efficiently. This ensures
continuous choke feeding of the crusher
chamber for optimal productivity.
Material from the pre-screen can be
diverted to a stockpile via an on board by-pass
conveyor, or join the crushed product on the
main belt.
Meanwhile, the Terex Finlay 684 is
described as a compact, easily-transportable
machine that offers operators rapid set up and
tear down times. Its new screenbox features
three full size 4.3 m x 1.7 m (14.1 x 5.6 ft)
inclined decks giving a screening area of 21.9
m
2
(774 ft
2
). The screenbox features quick
wedge tensioning, access holes and bottom
deck hydraulic tensioning system to reduce
time required for mesh changes.
All four discharge conveyors hydraulically
fold for transport, providing the operator
with rapid set up and tear down times. A
high performance 1.05 m (3.5 ft) belt feeder
with hydraulic gearbox drive is fitted to the
machine as standard.
Terex Washing Systems has introduced the
new Aggresand 206 washer. According to the
company, this larger model shares the modular
features of the Aggresand 165 launched in
2013, including ease of transportation and
rapid set-up time. It also comes pre-wired
and pre-plumbed, and with a human machine
interface (HMI) Control System. The official
launch and unveiling of the Aggresand 206
will take place at the Hillhead Show near
Buxton, UK, in June.
The 206 uses the Terex 6.1 x 1.8 m (20 x 6
ft) inclined rinser screen and will be available
in two or three deck options. It is designed for
the larger producer looking to increase the
tonnage per hour up to a maximum of 400
tonnes/hour.
EXPANDING THE RANGE
Sandvik was another company to showcase
new crushing and screening equipment,
including its CH550 stationary crusher and
its Q1451 mobile crusher and screener. In
autumn 2013, the company expanded its
mobile crusher portfolio with the introduction
of the new QS441 and QS331 track-mounted
cone crushers.
Its QI341 impact crusher is now available
with an optional hanging screen system, and
Sandvik has unveiled the QE141, the latest
Vegas debut for
Telsmith T400 cone
Telsmith, part of the Astec group of companies, used
ConExpo to give an official launch for its new high capacity
T400 cone crusher, which it claims offers the largest
clearing stroke and crushing force in its class.
The T400 delivers 300 kW (403 hp) performance
and offers a throughput of between 135 to 545
tonnes per hour. Telsmith says that the new unit has
been engineered for maximum productivity and lower
operating costs, and features a large clearing circuit
engineered to safely
and quickly allow uncrushab
le
materials to pass. This new cone is ideal for tough
mining and quarrying applications, says the company.
The T400 features a 1.4 m (4.6 ft) receiving hopper,
replaceable mainframe liners and epoxy-secured
manganese steel crushing members. A single bowl is
used for all liners over its range of operation to minimise
downtime and reduce inventory costs.
The T400 also features a new and improved patent-pending
anti-spin feature that prevents head spin to extend manganese life
mounted on the top of the machine, as with other key components, to offer easy top service
access. It has been designed to operate with pressure lubricating oil, while not using a
gear box and a separate hydraulic circuit. It has been designed with six cylinders – fewer in
number than that of conventional units – yet offers the largest crushing force available, says
the company.
