The Terex Finlay J-1170 is a high performance primary mobile jaw crusher built around the renowned and aggressive Terex 44 by 28 in. (111.7 by 71 cm) jaw crusher, with a proven track record in recycling, aggregate production and mining applications.

The Terex 44 by 28 in. jaw chamber provides excellent material reduction and product sizing in the processing of blasted quarry rock and ore material. The jaw chamber also is available with optional hydraulic release, a useful 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, according to the manufacturer.

The machine is powered by either a Tier III/Stage 3A Caterpillar C9 350 hp (261 kW) or a Tier IVi Scania DC9 70A 350 hp (257 kW).

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 by-pass conveyor, or join the crushed product on the main belt.

The large 12.55 cu. yds. (9.6 cu m) hopper has hydraulically folding sides and a hydraulic self-locking mechanism to provide efficient and faster machine set up and tear down times.

“The J-1170's [49.6 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.
