Technique Principle
The wood crusher utilizes a high-speed rotor equipped with specialized blades (7-type, straight, centrifugal). Material (1-1500mm) fed into the chamber undergoes โโmulti-stage fragmentationโโ. Initial impact and coarse cutting by primary blades is followed by โโprecise shearingโโ and further reduction via centrifugal force. The combined mechanical action (impact, shear, grinding, friction) efficiently โโreduces raw wood, bamboo, stalks, and wasteโโ into consistent wood fiber, chips, or sawdust. This โโcontrolled particle sizeโโ is optimized for applications like pulp, biomass pellets, engineered boards, and mushroom substrate.

Working Principle
Material enters the machine through โโtwo specialized feed chutesโโ that classify and route inputs based on their physical properties. Soft or fibrous materials like bamboo stalks and thin branches are directed through the โโ”Feed chute go to blades”โโ channel, where they encounter โโstationary Cut Bladesโโ positioned near the rotorโs periphery.
As the central โโRotorโโ spins at high velocity, it forces incoming material against these razor-sharp blades, executing a guillotine-like shearing action that slices fibrous matter into uniform strips. Simultaneously, bulky or rigid materials such as logs and thick branches enter via the โโ”Feed chute go to hammers”โโ chute, dropping directly into the impact zone. There, โโfreely swinging Hammersโโ mounted radially on the rotor deliver high-impact blows, shattering solid wood through kinetic collision and centrifugal fragmentation against the chamber walls.
All materials โ both pre-sliced strips and impact-fractured fragments โ then converge in the โโgrinding chamberโโ, where the rotating hammers continue pulverizing them in a dynamic recirculation loop. Centrifugal forces propel particles outward, while rotor-generated airflow fluidizes the mixture. Oversized pieces rebound off the chamber linings back into the hammer trajectory for repeated crushing, while properly sized particles escape through an integrated sizing screen. The crushed output is pneumatically conveyed out as consistent wood chips or sawdust, with the dual-feed system and sequential blade-to-hammer processing enabling energy-efficient, clog-free operation tailored for industrial volumes.
Product Structure
| Components | Function |
| โโDual Feed Chutesโโ | Optimizes energy use: Soft materials bypass hammer impact โ reduces wear by 40%. |
| โโCut Blades + Hammersโโ | Sequential reduction: Shearing prevents fiber wrapping; hammers pulverize rigid matter. |
| โโFreely Swinging Hammersโโ | Auto-adjusting force: Hammers retract on overload โ protects rotor/motor from jams. |
| โโRotor-Driven Airflowโโ | Passive material handling: Eliminates separate conveyors โ lowers power draw by 15%. |
Core Advantages
