Terex Finlay’s new J-1170 high performance primary mobile jaw crusher is built around the renowned and aggressive Terex 1,100mm x 700mm jaw crusher.

The company says that with a proven track record in recycling, aggregate production and mining applications, the jaw chamber provides “excellent material reduction and product sizing in the processing of blasted quarry rock and ore material,” while the Terex 1,100mm x 700mm jaw chamber is also available with optional hydraulic release, an excellent feature when 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 either a Tier 3/Stage 3A Caterpillar C9 261kW or a Tier 4i Scania DC9 70A 257kW engine.

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 stock pile via the on-board bypass conveyor or join the crushed product on the main belt. 

The large 9.6m³ 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 J-1170’s 45tonne 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 Nigel Irvine, sales and marketing director.

Terex Finlay says key features are:


Terex 1,100mm x 700mm jaw crusher for high capacity and large reduction ratios in quarrying, mining, demolition and recycling applications.

Optional hydraulic release for demolition and recycling applications.

Compact dimensions and quick set-up for contract crushing as well as demanding in-pit applications.

45tonne transport weight for easy transport of machine between work sites.

Full CANBUS control system.

Hydraulically assisted CSS adjustment to minimise downtime and offer quick adjustment.

Fuel economy is said to be “excellent.”

Safe, quick and easy service points for regular maintenance.
