CRUSHING&SCREENING
Nordberg C106 single toggle jaw crusher designated as the
Liugong LM J106.Themachine was joined on the stand by the
LM S48 tracked screen.
Both are designed for the Chinese market, with the crusher
featuring a diesel delivering 194 kW certified to Tier II and
the latter, weighing in at 32 tonnes, featuring a Tier III engine
delivering 86 kW.
According to the company, they are designed for crushinghard
stone and recovering building materials in quarrying, mining,
cement,municipal road and bridge construction.
Crushers
Precision and efficiency are key to Irock’s latest crusher, theTC-
20, whichmade its debut at the Conexpo industry event in Las
Vegas earlier this year.
Combining a larger feeder and a high performance four-bar
impactor, the company said it produces a uniform, cubical
product, with hydraulically adjustable aprons providing added
control over sizing.
According to Irock, its latest machine has the versatility to
process soft to medium rock, recycled concrete and recycled
asphalt.
The crusher’s rotor measures 40 inches
(1,016 mm) by 56 inches (1,422 mm)
and can process a variety of materials up
to24 inches (610mm) indiameter.A440
hp (328 kW) Caterpillar C-13 ACERT
Tier 3 engine powers themachine, which
canprocess up to 500 tonnes per hour.
The tracked crusher features a
fixed, Hardox steel hopper offering a
11.4 m
3
capacity. It is paired with a 52
inch (1,320mm) vibrating grizzly feeder,
which has three quarter inch (19 mm)
liners on the pan and side walls. The
feeder is up to 3 feet (914 mm) longer
than comparableunits,making it possible
to feedmaterial with a largewheel loader.
Consistent product development in
terms of flexible design and operational
readiness is an approach that Rockster
says it has applied to its range of crushers
–with its R1100DSno exception.
Featuring its multi-function display the
machine’s crushing gap can be adjusted
fully hydraulically and continuously, so
the final material can be defined simply
and easily, aiding precision of screening
curves.
The conveying velocity continuously
adapts the crusher load and the operating
pressure of the main conveyor, which
prevents overload and downtimes. If
necessary, the vibrating feeder can be
infinitely controlledmanually via the remote control.
Competingwithharsh climates is often a key consideration for
equipment for the crushing and screening sector.
One exampleof performanceunder testing conditions isSBM’s
STE 100.65.T combined with its Remax 132 Eco operating in
theTschita region of Siberia.
The mobile track-mounted primary and secondary crushing
unit, consistingof a jaw crusher and an impact crusher, is loaded
herewith especiallyhard and toughgabbrobasaltwith a feed size
of up to 600 mm. With a throughput of some 200 tonnes an
hour, a final grain size of 0-45mmwas achieved.
