At CONEXPO 2014, Terex will introduce its new Finlay J-1170 primary mobile jaw crusher and Finlay 684 tracked mobile inclined screen.
The Finlay J-1170 is a high performance machine built around the renowned and aggressive Terex 1,100 mm x 700 mm (44 in. x 28 in.) jaw crusher, with a proven track record in recycling, aggregate production and mining applications.
The Terex 1,100 mm x 700 mm jaw chamber provides excellent 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, 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 IIIA Caterpillar C9 261 kW (350 hp) engine or a Tier 4 Interim Scania DC9 70A 257 kW (350 hp) 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 fine 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 9.6 m³ (12.55 yd³) 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 tonne 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,” says Nigel Irvine, Sales and Marketing Director.
Key Features:
- Robust proven Terex 1,100 mm x 700 mm 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 make the J-1170 the optimum solution for contract crushing as well as demanding in-pit applications.
- 45 ton / 99,600 lbs. transport weight ensures easy transport of machine between work sites.
- Full CANBUS control system.
- Hydraulically assisted closed side setting adjustment minimizes downtime and offers quick adjustment.
- Excellent fuel economy
- Safe, quick and easy service points for regular maintenance
The new Terex Finlay 684 is a highly versatile and adaptable machine engineered and built for working in quarrying, mining, construction and demolition debris, topsoil, recycling, sand, gravel, coal and aggregate applications.
The Terex Finlay 684 is a compact, easily transportable machine that offers operators rapid set-up and tear-down times. The new screenbox on the Finlay 684 features three full size 4.3 m x 1.7 m (14 ft.x 5 ft. 7 in.) inclined decks giving a large screening area of 21.9 m2 (236 ft.2) to provide efficient screening and high capacity. The screenbox features quick wedge tensioning, access holes and a bottom deck hydraulic tensioning system to reduce time required for mesh changes. All four discharge conveyors hydraulically fold for transport. The fourth product ‘oversize plus’ conveyor can work at varying angles to accurately discharge material for recirculation and stockpiling
A high performance 1,050 mm (42 ft.) belt feeder, with hydraulic gearbox drive, is fitted to the machine as standard and has proven performance and versatility in demanding and varied working environments. The hopper has an 8 m³ (10.50 yd³) capacity as standard and can be fitted with a 14 ft. tipping grid or 12 ft. vibrating grid.
A Caterpillar C4 82 kW (111 hp) air cooled engine is used to power the machine. The heavy-duty crawler tracks, and optional radio remote control unit, make on-site mobility very easy.
This fully self-contained plant can be hydraulically folded and ready for transport in less than 30 minutes, making it the ideal machine for contract screening.
Key Features:
- New triple deck configuration with three full size decks 4.3 m x 1.7 m (14 ft. x 5 ft. 7 in.) with full catwalk access
- The fourth (oversize plus) conveyor can work at varying angles and can discharge from 15 to 24 degrees for recirculation to crusher or for stockpiling.
- Maximum utilization of three full size 4.3 m x 1.7 m (14 ft. x 5 ft. 7 in.) decks provides ultra-efficient screening capabilities even at small aggregate sizes.
- A combination of quick wedge tensioning, convenient access holes and hydraulic tensioning on the bottom deck ensure mesh set up and change out times are kept to an absolute minimum.
