New tracked mobile heavy duty screener
The new Terex® Finlay 893 (Fig.) is a highly versatile and aggressive machine engineered and built for working in quarrying, mining, construction and demolition debris, topsoil, recycling, sand, gravel, coal, ore and aggregate applications. This forward facing inclined modular configuration screenbox has a 6.1 x 1.83 m (20’ x 6’) top deck and a 5.5 x 1.83 m (18’ x 6’) bottom deck. Depending on the working application of the machine hydraulic adjustment can be used to vary the working range angle of the screen box between 14-18°. The screenbox top deck can be fitted with a variety of screening media including; mesh, punch plate, bofor bars and tines. The bottom deck can be fitted with mesh, punch plate & cascade fingers.
A high performance 1100 mm (44”) apron feeder and 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 10 m³ (13.1 yd³) capacity as standard. The machine is powered by either a Tier 3/Stage 3A Caterpillar C6.6 151 kW (202 hp) or a Tier 4i Caterpillar C4.4 129 kW (173 hp) and is equipped with three hydraulically folding discharge conveyors allowing for maximum stockpiling capacity and associated benefits of rapid set up and tear down times.
The heavy duty crawler tracks, and optional radio remote control unit, make on site mobility very easy. A key feature of the machine is the ability to hydraulically raise the screenbox 600 mm (24”) at the discharge end to provide additional clearance for ease of media change as well as routine maintenance of the screenbox and fines transfer.
The plant has the capacity to process at a rate of up to 800 t/h and can be fed either by a tracked mobile crusher or an excavator. This fully self-contained plant can be hydraulically folded and ready for transport in less than 30 minutes making it the ideal machine for large scale contract screening projects were a highly productive and dependable screen is paramount.
