Horizontal vs Inclined vs Banana Screens: Which Should You Choose?
Quick Decision Matrix
| Application | Horizontal | Inclined | Banana |
|---|---|---|---|
| Wet/sticky material | ✅ Best | ❌ Poor | ⚠️ Fair |
| Fine sizing (<10mm) | ✅ Best | ❌ Poor | ⚠️ Fair |
| High capacity (>500 TPH) | ⚠️ Fair | ✅ Best | ✅ Best |
| Limited headroom | ✅ Best | ❌ Poor | ❌ Poor |
| Mobile plants | ✅ Best | ⚠️ Fair | ❌ Poor |
| 4+ fractions | ✅ Best | ⚠️ Fair | ⚠️ Fair |
How Motion Type Affects Performance
Elliptical Motion (ETE Series - Horizontal)
- Longer material retention time ensures more sizing opportunities.
- Exceptional blinding reduction compared to standard strokes.
- Best for: sticky, wet, and flaky feeds.
Circular Motion (STE Series - Inclined)
- Relies heavily on gravity for high throughput.
- Simple maintenance profile.
- Best for: dry, coarse aggregates and bulk sorting.
Linear Motion (Banana)
- Multi-slope efficiency designed to thin out deep beds rapidly.
- Ultra-high capacities in massive operations.
- Best for: iron ore, high-tonnage bulk materials.
Real-World Selection Scenarios
Scenario 1: Quarry with 15% Moisture
- Problem: Blinding on inclined screen.
- Solution: ETE horizontal with 35° ellipse.
- Result: 40% efficiency gain with significant drop in blinding.
Scenario 2: Mobile Crushing Plant
- Constraint: 3.5m height limit for transportation.
- Solution: ETE1848 horizontal screen.
- Result: Fits transport envelope without structural rebuilding.
Cost Comparison (5-Year TCO)
When selecting your screen, always factor in:
- Initial purchase and installation modifications.
- Energy consumption based on motor and operation hours.
- Maintenance costs and interval frequency.
- Downtime impact — a cheaper screen catching blinding might cost thousands per week.
