By Andrew Macklin
May 26, 2015 – The new Terex Finlay 873 is designed to work after a primary crusher or on its own as frontline screening machine. This versatile and adaptable machine is suitable for working in quarrying, mining, construction and demolition debris, topsoil, recycling, sand, gravel, coal and aggregate applications.
This forward facing inclined modular configuration screenbox has a 3.66m x 1.52m (12’ x 5’) top deck and a 3.66m x 1.52m (12’ x 5’) bottom deck giving a total screening area of 14.4m2. Depending on the working application of the machine hydraulic adjustment can be used to vary the angle of the screen box between 13–19°. The top deck of screenbox can be fitted with a variety of screening media including; tines, bofor bars, punched plate and mesh. The bottom deck can be fitted with mesh or cascade fingers.
The hopper has a seven cubic metre capacity as standard with a drop rear door for use in conjunction with a mobile crusher.
The machine is equipped with three hydraulically folding discharge conveyors allowing for maximum stockpiling capacity and associated benefits of rapid set up and tear down times.
Additional features of the machine include; galvanized access ladders and catwalks fitted as standard to both sides of the screen box. Hydraulic raising of the screenbox discharge end provides additional clearance for screenbox and fines transfer conveyor maintenance.
