The sawdust machine operates through coordinated mechanical processes. Hydraulic pressure forces logs/branches (up to 750×480mm inlet size) onto a feed conveyor (illustrated chain system), consistently pushing material into the cutting chamber. A high-torque motor (55–200+ kW) drives a hardened steel disc/spindle at 940–1750 RPM, rotating arrays of replaceable HSS blades (168–840 units).

As wood enters the chamber, rotating blades impact and shear material against fixed breaker plates, progressively reducing fragments through repeated cutting and grinding. The machine’s optimized knife geometry and spindle speeds (model-dependent) maximize fiber separation while minimizing energy waste.

Crushed particles are forced against an interchangeable perforated screen (sieve) encircling the cutting zone. Only particles smaller than the screen’s mesh size (typically 2–5mm) escape, ensuring uniform sawdust output. Larger fragments recycle internally for further reduction, achieving near-100% material utilization.

Processed sawdust exits gravitationally or via pneumatic suction for collection. The machine’s robust construction (3,500–8,500kg weight) dampens vibration during high-capacity operation (up to 12 t/h output), while advanced models allow voltage customization (380V/50Hz standard) for global deployment. Continuous automation enables single-operator control from feeding to final output.
