The Terex Finlay 873 tracked mobile heavy-duty screener incorporates a forward-facing, inclined modular configuration screen box that has a total screening area of 155 sq. ft. Various types of screen media can be placed on the top deck of the screen box, including tines, punched plate and mesh. Either mesh or cascade fingers can be placed in the bottom deck. The screener comes with three hydraulically folding discharge conveyors, which boosts stockpiling capacity.
The Finlay 873 works after a primary crusher or on its own as a frontline screening machine. It works best on aggregates, sand and gravel, construction & demolition debris, topsoil or coal. Additionally, the machine includes galvanized access ladders and catwalks on both sides of the screen box.
