Primary Mobile Jaw Crusher
Has Hydraulic Options
Terex Finlay’s recently introduced J-
1170AS model is a high-performance
primary mobile jaw crusher built around
the proven Terex 1,100- x 700-mm
(44- x 28-in.) jaw crusher. The jaw chamber,
according to the company, provides
excellent material reduction and product
sizing in the processing of blasted material.
It has an optional hydraulic release
with automatic overload protection system
to prevent damage by uncrushable
items in the feed material. The machine
is powered by either a Tier 3/Stage 3A,
261-kW (350-hp) Caterpillar C9 or a Tier
4i, 257-kW (350-hp) Scania DC9 70A
diesel. Its hydrostatic transmission
offers reversible operation in the event
of a blockage. The hydrostatic system
also provides variable chamber speed to
suit given applications. The crusher features
hydraulic assist Chamber CSS
(Closed Side Setting) adjustment, which
can be changed in a matter of minutes.
The machine has a heavy-duty variable
speed vibrating grizzly feeder (VGF) with
integrated pre-screen, providing aggressive
action to separate fines material
efficiently. The variable speed VGF
ensures continuous choke feeding of the
crushing chamber for optimal productivity.
Material from the pre-screen can be
diverted to a stock pile via the onboard
bypass conveyor or joins the crushed
product on the main belt. The 9.6-m3
(12.55-yd3) hopper has hydraulically
folding sides and an innovative hydraulic
self-locking mechanism to provide
efficient and faster machine setup and
tear down.
