Product overviewThe Finlay® 684 3-Deck is a compact mobile inclined screener engineered for quarrying, mining, sand & gravel and recycling operations. It features three full‑size inclined decks (4.3 m x 1.7 m each) providing a large screening area, quick wedge tensioning, access holes and hydraulic bottom‑deck tensioning to reduce mesh change time. All four discharge conveyors are adjustable and hydraulically fold for transport. The fourth (oversize‑plus) conveyor offers variable tilt and side slew for precise discharge and recirculation. Hybrid on‑board electrical option and T‑Link telematics are available/standard.
