The Metso ST2.4 is a used tracked screener — also referred to as a screen plant — built for separating and sizing aggregate, rock, sand, gravel, and other bulk materials in quarry and mining applications. Metso is a well-established Finnish manufacturer of heavy processing and materials-handling equipment, serving the mining, quarrying, and construction industries worldwide with crushers, screens, and related plant.
At the heart of the machine is a 5-foot by 12-foot two-deck incline screen mounted on a heavy-duty box sub-frame. The screen runs on a robust two-bearing design with a manual tensioning system and increased screen media camber for improved and consistent tensioning across the decks. The screen angle is adjustable across a working range of 11 to 17 degrees, allowing the operator to tune performance to the material being processed.
Material is delivered to the screen by a feeder comprising a 6.3-cubic-yard lined hopper paired with a 48-inch heavy-duty hopper belt running at variable speed. Hydraulic wing walls are fitted to the hopper, easing material intake and accommodating different loading conditions.
The conveying system is comprehensive. A 48-inch-wide main conveyor with belt scraper handles primary discharge, supported by a 48-inch-wide under-screen conveyor for fines or mid-spec product. Two 32-inch-wide wing conveyors, each fitted with a belt scraper, manage the additional product fractions. All conveyors feature hydraulically adjustable height, giving flexibility in stockpile placement and truck-loading clearance.
Power comes from a Caterpillar C4.4 four-cylinder liquid-cooled engine rated at 100 horsepower. The plant includes remote automatic greasing for the pillow-block bearings, full walkway access around the screen plant, and wireless remote control for machine tracking and tramming.
The undercarriage runs on tracks with 16-inch-wide track pads and an 11-foot track length. The design provides maximum access to the gearbox and motor without requiring track removal. The machine was manufactured in 2017 and is offered here in used condition from a location in Montana, USA.
