dry screeningconstructionfor mining

Overview
The Terex Finlay 694+ portable inclined screen is designed for high‑production screening applications in quarrying, mining, sand and gravel, coal, woodchip and topsoil operations. The machine features three full‑size decks allowing efficient processing of fine, sticky and dirty materials. A large hopper with a variable speed belt feeder and multiple optional grid arrangements supports consistent feed.

Key features

• Triple full‑size screenbox: top and middle decks 6.1 m x 1.53 m, bottom deck 5.55 m x 1.53 m for high screening capacity.
• Optional hybrid electric powerpack enabling operation from external electrical supply or onboard engine.
• Hydraulically adjustable screenbox angle (approx. 18°–32°) to optimise throughput and separation.
• Foldable conveyors and wide folding catwalks for rapid onsite deployment and maintenance access.
• Optional integrated rinser module for wet screening applications.

Hopper / Feeder

• Discharge height example: ~4.97–5.1 m.

Oversize Plus Conveyor (optional)
• Belt width example: 650–800 mm (26"–32").
• Fixed or variable working angle; variable discharge height and swivel discharge for recirculation or stacking.

Middle Grade Conveyor
• Belt width: typically 800 mm (32").
• Working angle and speeds similar to oversize minus conveyor.

Fines Conveyor
• Belt width: typically 1200 mm (48").
• Working angle up to approx. 27°–28°.
• Speed and discharge height vary by configuration; standard discharge height around 4.4–5.5 m.

Undercarriage / Mobility
• Tracked undercarriage with shoe width examples ~500 mm.
• Travel speed approx. 0.8 km/h; gradeability around 32°.

Powerunit / Engine
• Engine options include Caterpillar C4.4 Tier 3/Stage IIIA ~97 kW (130 hp) and Tier 4 Final/Stage V dual certified ~102 kW (137 hp).
• Hybrid electric option available as an alternative drive solution.

Screenbox
• Top & middle decks: 6.1 m x 1.53 m (20' x 5').
• Bottom deck: 5.55 m x 1.53 m (18' x 5').
• Screen stroke and speed configurable; total screening area approx. 27–28 m².

T-Link telematics
• Compatible with Terex Finlay T-Link for remote monitoring of location, status and utilisation (manufacturer activation/service applies).

Notes
• Optional components (rinser screen, hybrid drive, tipping/vibrating grids, conveyor arrangements) increase site versatility. Maintenance access and fold‑down conveyors are designed for faster deployment and serviceability.
