The core of selecting a branch shredder lies in matching operational scenarios, material characteristics, and environmental compliance. During operation, strict adherence to safety norms, controlled feeding, and regular maintenance are essential to balance efficiency, safety, and equipment service life. Below are the detailed guidelines:
I. Key Selection Criteria
1. Clarify Operational Scenarios and Mobility Needs
| Scenario Type | Recommended Model | Power Source | Core Advantages |
| Mobile Operations (forest waste clearance, municipal greening) | Towable/Crawler-mounted mobile models | Diesel-powered | No external power supply required; flexible steering; suitable for complex terrain |
| Fixed Operations (nurseries, wood processing factories) | Stationary models | Electric (three-phase power) | Energy-efficient and low-noise; stable operation; high processing efficiency |
| Small-scale Operations (orchards, household use) | Lightweight mobile models (with universal wheels) | 220V single-phase power / small gasoline engine | Easy to move; ideal for small-diameter branches |
2. Match Material Parameters and Shredding Capacity
Feed Inlet Size: Select based on the maximum diameter of branches, with a recommended 20% margin. For example, choose a model with a 12cm inlet for daily processing of 10cm branches.
Shredding Mechanism:
Hammer mill type for thin branches (≤15cm diameter) – high efficiency;
Shear type for thick branches/stumps (≥20cm diameter) – high torque;
Drum cutter type for fluffy twigs;
Disc cutter type (equipped with screen for particle size control) for wooden sticks.
Screen Configuration: Choose fine screens if the output is for organic fertilizer, and coarse screens for fuel. Priority should be given to models with adjustable screens.
3. Power and Horsepower Matching
For operations without power supply or large-scale projects: Choose diesel-powered models (common horsepower range: 32–102 HP).
For operations with power supply or small processing volumes: Choose electric models (1.5–3kW for household use; 11kW+ three-phase power for industrial use).
Higher horsepower enhances the ability to process hard/thick branches, but it also leads to higher energy consumption and costs. Select based on actual needs.
4. Safety, Environmental Protection and Maintenance Convenience
Safety Features: Must-have configurations include emergency stop button, feed inlet protection, anti-kickback design, and push stick.
Environmental Compliance: Meet the requirements of GB36284-2023 (dust emission ≤18mg/m³). For sensitive areas, choose models equipped with pulse dust removal systems and sound insulation covers.
Maintenance Accessibility: Prioritize brands with comprehensive after-sales services, featuring easy blade replacement, clearly marked lubrication points, and easy-to-clean machine bodies.
5. Budget and Additional Functions
Household/ Small Orchard Use: Priced at several thousand yuan (1.5–3kW electric models with inlet diameter under 5cm).
Large-scale Engineering Projects: Priced at tens of thousands of yuan (diesel-powered models with inlet diameter 15–30cm).
Additional Functions: Collection bags/auto-unloading systems, pre-installed impurity removal devices, and adjustable feed roller speed can improve operational efficiency.
II. Operation Tips
1. Pre-operation Preparation
Conduct a no-load test run for 1–2 minutes to check for abnormal noise and vibration. Ensure the belt tension is proper and lubrication is sufficient (apply high-speed grease to bearings/gears).
Remove soil, gravel, iron nails, and other debris from materials. Cut thick branches into sections ≤50cm to avoid jamming and blade damage.
Wear protective gear (goggles, gloves, earplugs). Never feed materials by hand; use a push stick exclusively.
2. Standard Operating Procedures
Feeding Principle: Feed materials uniformly and continuously. The diameter of a single branch should not exceed 80% of the rated maximum to prevent clogging and overload.
Abnormality Handling: Stop the machine immediately if abnormal noise or vibration occurs. Disconnect the power supply before inspecting the blades, cutter shaft, and screen. Restart only after troubleshooting.
Shutdown Sequence: Stop feeding first → Run idle for 1 minute to clear residual materials → Turn off the power supply/engine → Disengage the power source (power take-off/clutch).
3. Maintenance Essentials
Daily Maintenance: Clean the machine body after each operation; inspect blade wear and sharpen or replace blades in a timely manner. Grease bearings every 50 hours of operation; replace gearbox oil regularly.
Regular In-depth Maintenance: Inspect belt/chain tension and wear weekly; check for screen damage/deformation monthly; disassemble and inspect cutter shaft and rotor balance quarterly.
Long-term Storage: Clear residual materials, apply anti-rust oil, store in a dry and well-ventilated area, disconnect the power supply, and drain all fuel.
III. Pitfall Avoidance and Efficiency Enhancement Tips
1. Pitfall Avoidance
Do not blindly pursue high horsepower (select based on actual needs).
Do not ignore dust and noise emissions (ensure compliance and minimize impact on surrounding areas).
Avoid purchasing models without after-sales service or with low-quality blades (all-steel blades are more durable).
2. Efficiency Enhancement Tips
Shred wet and dry branches separately (wet branches prevent clogging; dry branches reduce dust).
Use collection bags or trailers to improve material transportation efficiency.
Utilize shredded materials for composting, mulching, or as fuel to achieve resource recycling.
