Horizontal Baler Anti-Rebound Systems
Anti-rebound devices in horizontal balers maintain material compression through various technical approaches, each with distinct mechanisms and applications.
- Mechanical Locking: Uses ratchet-baffle mechanisms with springs/cylinders. After compression, the ratchet engages to prevent ram retreat. Wear inspection required every 500 cycles.
- Hydraulic Pressure-Maintaining: Employs check valves and accumulators (typically 10-15 bar) to sustain cylinder pressure. ±0.5% pressure accuracy via real-time sensors.
- Electrical Braking: Servo motors apply 200-400Nm counter-torque within 50ms. Encoders provide 0.01mm position feedback.
- Composite Systems: Combines mechanical primary locking with hydraulic secondary pressure (5-7 bar). Handles materials with >30% rebound tendency.
Performance Comparison: Mechanical systems suit <5 ton bales,
Hydraulic maintains ±1mm compression for elastic materials,
Electrical achieves 120+ cycles/hour,
Composite systems reduce rebound by 85-92% in demanding applications.
Selecting the appropriate anti-rebound system depends on material characteristics (elasticity, density), production requirements (speed, precision), and maintenance capabilities. Composite systems offer the highest performance but at 25-40% higher initial cost.
