Terex Finlay has announced the introduction of its new 873 tracked two deck screen that it says has been designed to work behind a primary crusher or on its own as a frontline screen. It is suitable for use in a wide range of applications in the quarrying, mining , construction and demolition sectors to process topsoil, sand, gravel, coal and aggregates.
The forward facing modular screenbox has top and bottom decks that both measure 3.6 x 1.52 m (12 x 5 ft) giving a total screening area of 14.4 square metres (155 square feet) and the angle of the screen box can be adjusted between 13 and 19°, depending on the application. The top deck of the 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 7 cubic metre (248 cubic foot) 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 galvanised 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.
