Terex Finlay J-1170 Primary Mobile Jaw Crusher

The new Terex Finlay J-1170 is a high-performance primary mobile jaw crusher built around the renowned and aggressive Terex 1,100- x 700 mm (44- x 28-in.) jaw crusher, 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. It 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 (350 hp) or a Tier 4i Scania DC9 70A 257kW (350 hp).
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 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 9.6 cu. m (12.55 cu. yd.) 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 45-ton 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.
