The Terex 1100mm x 700mm
(44” x 28”) jaw chamber provides material reduction and product sizing in the
processing of blasted quarry rock and ore material. The jaw chamber is also
available with optional hydraulic release, a feature recommended for crushing construction
and demolition debris. The hydraulic release option has an automatic overload
protection system to prevent damage by uncrushable items in the feed material.

 

The machine
is powered by a Tier 4i Scania DC9 70A 257kW (350hp).


Hydrostatic transmission of the jaw chamber offers operators 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, and 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 an
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 stockpile
via the on board by-pass conveyor, or join the crushed product on the main
belt. 

 

The large 9.6m³ (12.55yd³) hopper has hydraulically
folding sides and an innovative hydraulic self-locking mechanism to provide efficient
and faster machine set up and tear down times.

 

“The Terex Finlay’s J-1170’s,
99600lbs transport weight and compact dimensions mean lower transport costs
between and within crushing sites.
The robust and intelligent
chassis design, with good clearance on both ends, also enables safe and easy
loading onto all transport trailers.
When
you combine these factors with the excellent crushing capabilities the machine
easily meets the demands of owner operators and crushing contractors, said
Keith McCann, sales and
marketing director.
