Swing Granulator
The Swing Granulator is a mechanical processing unit designed for particle formation through centrifugal force and oscillatory motion. Its core mechanism involves a rotating main shaft with triangular fillets uniformly fixed along its circumference, optimized for material fragmentation and granulation. The system employs a dual-bearing configuration: one end fixed in a stationary bearing (e.g., deep groove ball bearing) and the other in a transmission bearing (e.g., tapered roller bearing for axial load tolerance)
Triangular Fillet Assembly: Three or more replaceable triangular fillets (hardness: HRC 58–62) with intubation tubes for rapid blade alignment and gap adjustment (tolerance: ±0.1 mm via regulating screws).
Tangential-Feed Cutting Chamber: Anti-jamming design with 304 stainless steel auger entry (diameter: 150–300 mm) for continuous material conveyance.
Variable Oscillation Frequency: Adjustable swing amplitude (5–15 mm) and rotor speed (800–1,500 RPM) via VFD-controlled induction motor (power range: 7.5–22 kW).
Modular Screen Cradle: Top-hinged cover with interchangeable perforated screens (aperture: 2–8 mm) for particle size control.

Common Failures & Solutions
Technical specifications derived from mechanical engineering standards and industry-specific operational data.
| Issue | Root Cause | Resolution |
|---|---|---|
| Uneven Granule Size | Worn triangular fillets (>0.3 mm edge radius) or screen blockage | Replace fillets; clean screen with compressed air (≥6 bar) 1 |
| Vibration Overload | Bearing wear (radial play >0.05 mm) or unbalanced rotor | Lubricate bearings (NLGI #2 grease); perform dynamic balancing 1 |
| Material Clogging | Excessive moisture (>5% w/w) or undersized auger | Pre-dry feedstock; upgrade to larger auger diameter 13 |
| Motor Overheating | Overload (current >110% FLA) or inadequate cooling | Reduce feed rate; verify ventilation (min. 20 m³/h airflow) |
Recommended Replacement Parts
Operational Hours vs. Calendar Time: Prioritize intervals based on actual runtime (e.g., 4,000–6,000 hrs for bearings) rather than fixed months.
| Component Name | Replacement Interval | Key Influencing Factors |
|---|---|---|
| Perforated Screens | 3–6 months | Aperture clogging frequency, material abrasiveness (e.g., SiO₂ content >5%), screen thickness (2–4 mm) |
| Main Shaft Bearings | 18–24 months | Axial/radial load cycles, lubrication interval (NLGI #2 replenishment), temperature (>70°C accelerates wear) |
| V-Belts | 12–18 months | Tension loss (>15% slippage), cracking/delamination, motor power (22 kW belts degrade faster) |
| Seal Rings (NBR/FKM) | 12 months | Chemical exposure (pH <4 or >10 reduces lifespan), thermal cycling (>100°C degrades elasticity) |
| Lubrication Grease | Quarterly | Contamination (dust/particle ingress >0.1%), operational hours (>2,000 hrs/quarter) |
