ABS Spiral Chutes

ABS Spiral Chute Structural Composition

• Spiral Groove Assembly – The core working component is constructed from interlocking ABS plastic spiral segments, featuring a precisely molded cubic parabolic cross-section for optimal particle separation. The ultra-smooth inner surface enhances flow dynamics while resisting wear.
• Feed Distribution System – Comprises a multi-pipe ore distributor and feed chute at the top, ensuring uniform slurry distribution across all spiral heads to maximize separation efficiency.
• Support Framework – A rigid steel structure made of angle or channel steel, including vertical columns and a stabilizing tripod base, maintaining perfect vertical alignment during operation.
• Product Collection Mechanism – Features an adjustable valve-block splitter at the spiral outlet, allowing precise control over concentrate, middlings, and tailings discharge widths for targeted recovery.
• Concentrate Launder System – Concentric ring-shaped collection funnels strategically positioned to receive and channel separated products by density grade into designated discharge points.

Working Principle of ABS Spiral Chutes
The separation process is driven by gravity and centrifugal forces as the slurry flows down the spiral. During operation, denser mineral particles migrate inward due to greater inertial forces, while lighter gangue materials are pushed outward by hydrodynamic drag. Laminar flow conditions promote distinct layer formation, allowing clean separation of heavy concentrates (e.g., ilmenite, zircon) from tailings. Without motors or complex mechanisms, its energy-free operation makes the chute ideal for remote or low-power environments, delivering high recovery rates for minerals in the 0.02–0.3mm size range.
