Working principle of drum chipper

Drum wood chipper By driving the cutter drum to rotate at high speed through the motor, the blade cuts the incoming material as it rotates with the cutter drum, cutting it into pieces. Qualified pieces are discharged through the mesh screen holes, and large pieces are cut again in the machine until they meet the requirements.

This device utilizes a combination of rotation and cutting to achieve fast and uniform chip processing of materials.

• Multiple flying knives are installed on a high-speed rotating drum wheel (knife roller), which achieves continuous cutting through the combined action of centrifugal force and feed speed.
• The flying knives are made of high-strength alloy steel and are fixed with special bolts and pressure blocks to ensure cutting stability.
• Feeding System:
• The upper and lower feeding rollers adjust their gap via a hydraulic system to accommodate raw materials of varying thicknesses (e.g., logs, branches, and boards).
• The feeding speed is adjustable and synchronized with the knife roller speed to control chip length (typically adjustable between 20–38 mm).
• Discharge and Screening:
• The cut wood chips are discharged via airflow or mechanical conveyance. Qualified chips fall through the screen, while larger pieces are automatically returned for re-cutting.

Types of wood chippers：drum chipper vs disc chipper

• Drum-type chipper
• Cutting mechanism: Several flying knives are mounted on a rotating drum wheel, which cuts wood through high-speed rotation. The outer edge of the drum wheel has square holes to facilitate the discharge of wood chips.
• Raw material adaptability: It is good at processing irregular raw materials such as branches, small-diameter wood, and board skins with a diameter or thickness of less than 120 mm, and can also cut non-wood materials such as bamboo and straw.
• Application Scope: Paper mills, fiberboard factories, wood chip export bases, and the biomass energy sector.
• Disc-type chipper
• Cutting mechanism: Cutting blades are mounted on the cutting disc, which directly cuts wood by rotating. The blade protrusion can be adjusted to meet different specification requirements.
• Raw Material Adaptability: Suitable for processing regular logs with diameters ranging from 30 to 350 millimeters, featuring high cutting precision and uniform chip quality.
• Chip Quality: Clean cuts, minimal wood debris, and minimal disc wear.
• Typical Applications: Pulp and paper mills, high-density fiberboard production, and other applications requiring high-quality wood chips.
• Mobile wood chipper
• Features: Can be moved to forest areas for operation, equipped with a diesel engine or motor, highly flexible.
• Application scenarios: Forest logging sites, small wood chip processing points, reducing raw material transportation costs.

The application scope of drum chippers

Suitable for a wide range of industries, such as mechanical charcoal factories, artificial board factories, biological granulation, papermaking, sawdust production, feed processing, breeding farms, mushroom cultivation bases, landscaping, etc., it is an ideal wood chip processing equipment for a large number of users.

• Paper industry: Provide uniform wood chips, optimize pulp efficiency, and reduce raw material waste.
• Artificial board manufacturing: High cutting accuracy ensures uniform particle board/fiberboard structure and enhances product strength.
• Biomass energy: converting forestry waste into fuel pellets to support the development of green energy.
• Non wood material processing: Suitable for bamboo, sugarcane, etc., expanding application scenarios (such as bamboo products, pulp and paper).
