Construction screening unit 883+ Triple Shaft

mobilefor bulk materials

Description The Finlay® 883+ triple shaft mobile scalping screener is designed for dry and sticky applications including quarrying, mining, sand and gravel production, construction and demolition debris and recycling. The triple-shaft screenbox incorporates two full-size 4.8 x 1.53 m (16' x 5') decks and an oval motion stroke to deliver aggressive screening action while reducing plugging and blinding across the decks. The model is available with hybrid power (on-board electric motors plus standard engine) to allow operation from external power or the onboard engine.

Key features

• Higher G-force and larger, adjustable stroke and angle of the triple-shaft screenbox for improved productivity in dry and sticky materials.
• Multiple media options (Bofor bars, finger screens, woven mesh, punch plates) for applications from fine screening to heavy scalping.
• All media configurations are compatible with both standard and triple-shaft screenboxes.
• Banana profile of the bottom deck maximizes fine material separation.
