Circular vs Linear Vibrating Screen: Differences, Applications, and Selection Guide
1. Working Principles & Design
- Circular Vibrating Screen:
- Motion: 3D elliptical trajectory (long axis for throwing, short axis for vibration), material moves spirally.
- Drive System: Single/double eccentric shafts with gear synchronization, amplitude 4-8mm, frequency 700-1000rpm.
- Deck Angle: Adjustable 15°-25° via counterweight modification.
- Linear Vibrating Screen:
- Motion: Straight-line vibration from dual-motor reverse rotation, material jumps parabolically.
- Drive System: Two identical vibratory motors, amplitude 2-6mm, frequency 900-1500rpm.
- Deck Angle: 0°-10° adjustable via motor eccentric block angle.

3. Application Scenarios
- Circular Screen Uses:
- Mining: Iron/copper ore grading (0-5mm, 5-20mm);
- Construction: Sand gradation control (FM 2.3-3.0);
- Recycling: Construction waste separation.
- Linear Screen Uses:
- Coal: Raw coal sizing (+50mm lump coal separation);
- Metallurgy: Sinter cooling (≤150°C);
- Agriculture: Grain cleaning and grading.
4. Selection Strategy
- Step 1: Material Analysis
- Size:
- Fine particles (<3mm) → Circular screen;
- Coarse particles (>10mm) → Linear screen.
- Moisture:
- Wet/sticky material → Linear screen with cleaning balls;
- Dry material → Circular screen.
- Size:
- Step 2: Production Needs
- Throughput:
- <500t/h → Linear screen (energy-saving);
- ≥500t/h → Circular screen.
- Accuracy:
- ±0.5mm tolerance → Linear screen;
- ±1mm tolerance → Circular screen.
- Throughput:
- Step 3: Cost Evaluation
- CAPEX: Circular screens cost 10-15% more;
- OPEX: Linear screens have lower maintenance costs.
Conclusion: Circular screens dominate mining grading, while linear screens excel in coal applications.
