Rice Huller Rubber Rollers Key Components Applications
Core Functionality
Rice huller rubber rollers are critical components in rice milling machinery. They enable shell removal by counter-rotating at different speeds, creating compression and shearing forces that separate husks from rice grains.
Design Features
- Material Composition:
- Outer layer rubber hardness (Shore A): 90–95 degrees, adjustable for climate and grain types.
- Color options: Brown, black, white, red, yellow, purple, gray, cream, blue, green (customizable).
- Structural Types:
- Wheel-type: Bolt-fixed with 3–4 mounting holes.
- Sleeve-type: Cone-based mounting for quick replacement.
- Lap-type: Interlocking design for secure fixation.
Performance Optimization
- Temperature Control:
- Ideal operating temperature: ≤50°C to prevent premature aging.
- Hardness reduction: 4–8 Shore A degrees above 60°C.
- Pressure Adjustment:
- Roller gap (nip): 0.5–0.8 mm for optimal husk removal.
- Pressure plates ensure uniform force distribution.
Maintenance Tips
- Balancing:
- Regular static balancing to minimize vibration and wear.
- Replace rollers if imbalance exceeds 2 Shore A degrees.
- Storage:
- Keep unused rollers in dry, dark areas to avoid UV damage.
- Wrap in protective film to prevent ozone exposure.
