Terex Finlay launch tracked mobile screen at Intermat 2012

Terex Finlay to launch new 684 tracked mobile inclined screen at Paris show

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 screen box on the Finlay 684 features three full size 4.3m x 1.7m (14ft x 5ft 7in) inclined decks giving a large screening area of 21.9m2 (236ft2) to provide efficient screening and high capacity. The screen box features quick-wedge tensioning, access holes and a bottom deck hydraulic-tensioning system to reduce time required for mesh changes.

For ease of transportation, all four discharge conveyors fold hydraulically. The fourth product ‘oversize plus’ conveyor can work at varying angles to accurately discharge material for recirculation and stockpiling.

A high-performance 1,050mm (42in) 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 a 8m³ (10.50yd³) capacity as standard and can be fitted with a 14ft tipping grid or 12ft vibrating grid.

A Caterpillar C4 82kW (111hp) 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.

The fully self-contained plant can be hydraulically folded and ready for transport in less than 30 minutes making it suitable for contract screening.

Key features:

  • New triple-deck configuration with three full-size decks with full catwalk access
  • The fourth (oversize plus) conveyor can work at varying angles and can discharge from 15 degrees to 24 degrees for recirculation to crusher or for stockpiling
  • Maximum utilization of three full size 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.
