Guoyu brush wood chippers employ a ​​dual-mechanism shredding process​​ integrating high-speed mechanical cutting with aerodynamic forces. The diesel or electric motor drives a rotor fitted with hardened steel blades that initially fracture branches through direct ​​impact-shearing​​. Simultaneously, rotational energy generates a ​​cyclonic airflow vortex​​ (>80 m/s) around the blade path.

Material entering the feed throat undergoes:
​​Primary Fragmentation​​: Blades forcibly slice and tear fibers (shear force >200 MPa);
​​Aerodynamic Acceleration​​: Torn particles become airborne, colliding with rotor hoods and each other at centrifugal velocities;
​​Secondary Attrition​​: Impact collisions pulverize semi-processed fragments against tungsten carbide-lined chamber walls.

Optional ​​calibrated screens​​ (Φ5–50mm) ensure output quality:
Particles meeting size criteria eject instantly through discharge airflow;
Oversized fragments recirculate via turbulent eddies for repeated crushing.

This synergy achieves ​​>95% reduction efficiency​​ while minimizing blade wear through distributed energy transfer—optimal for mixed softwoods and hardwoods.
