Drum Chipper for Wood Chip and Biomass Preparation
- Drum chipper for logs, slabs, branches and biomass raw material preparation.
- Used before hammer milling, drying and pelletizing in wood pellet projects.
- Model selection depends on feed size, chip size, capacity, voltage and line layout.
Drum Chipper Selection Overview
A drum chipper is used when logs, branches, slabs or waste wood need to be reduced into chips before grinding, drying or pelletizing. For industrial projects, the main selection points are feed opening, knife configuration, chip size, motor power, feeding stability and the downstream equipment layout.
TCPEL supplies drum chippers for preparing wood chips from logs, branches, slabs and biomass raw material. In a wood pellet or biomass fuel line, the drum chipper is normally installed before the mulino a martelli, essiccatore rotante e macchina per pellet di legno.
The suitable model depends on maximum raw material size, required chip size, target capacity, working hours, voltage and feeding method. TCPEL can recommend a single drum chipper or a complete front-end preparation system according to the confirmed project scope. For more selection details, see the drum chipper buying guide.

What Is a Drum Chipper?
A drum chipper is a wood chipping machine that uses knives mounted on a rotating drum to cut logs, slabs, branches and biomass residues into chips. In pellet projects, it is normally used before hammer milling, drying and pelletizing so that large wood pieces can be prepared for the next process.
The suitable machine is selected according to raw material size, target chip size, required capacity, working hours, motor power, voltage and site layout. Actual output depends on wood species, moisture, blade condition and feeding stability.
How a Drum Chipper Works
Raw material is fed into the inlet and guided toward the cutting drum. The knives cut the wood against a counter knife, and the chips are discharged for storage, screening or further grinding. Stable feeding and sharp knives help produce more consistent chips and reduce overload risk.
Where It Fits in a Pellet Line
- Chipping: logs, slabs or branches are reduced into chips.
- Rettifica: a mulino a martelli prepares smaller particles for pelletizing.
- Drying: a essiccatore rotante adjusts moisture when raw material is too wet.
- Pellettizzazione: prepared material is pressed by a macchina per pellet di legno or biomass pellet line.
Drum Chipper vs Disc Chipper
A drum chipper is usually considered for larger feed size, continuous operation and higher wood preparation demand. A disc chipper can be suitable for smaller logs, branches or compact front-end layouts. The final choice should be based on material photos or videos, target chip size, capacity and working hours.
Key Selection Points
- Maximum raw material diameter and length before chipping.
- Required chip size for the downstream hammer mill or biomass process.
- Expected capacity and daily working hours.
- Knife material, counter knife adjustment and wear-part replacement plan.
- Feeding conveyor, discharge conveyor, magnetic separator or dust-control requirement.
- Local voltage, phase, frequency and electrical cabinet requirement.
Operation and Maintenance Notes
Operators should check blade sharpness, bearing lubrication, conveyor condition, guards, bolts and discharge area before regular production. Mixed raw material may contain sand, stones or metal pieces, so material cleaning and magnetic separation should be considered when required.
Information Needed for Quotation
Before quotation, send raw material type, maximum size, moisture condition, required chip size, target output, voltage and destination port. TCPEL can then recommend a single drum chipper or a complete preparation section for a biomass or pellet production line.

TCPEL supplies drum chippers for wood chip preparation before biomass and wood pellet production. The machine can be selected according to raw material size, required chip size, target capacity, motor power, voltage and line layout.
For a complete pellet project, the drum chipper can work with a mulino a martelli, essiccatore rotante, macchina per pellet di biomassa, cooler, screener and packing machine.
Main Features and Wear Parts
TCPEL drum chippers are selected according to raw material and line requirements. The points below describe common machine areas buyers should check before quotation and production planning.
The crushing chamber is covered for safe operation and maintenance access. For blade inspection or cleaning, the cover can be lifted according to the machine configuration and operating manual.
The knife material and hardness should match the wood type and working hours. Blade service life depends on raw material cleanliness, hardwood ratio, feeding stability and maintenance practice.
The feed roller helps guide material into the cutting area. Stable feeding can reduce overload risk and support more consistent chip size before hammer milling.
The machine body is designed for stable running during wood chip preparation. Foundation, installation space and feeding/discharge direction should be confirmed with the final layout.
The feeding chain conveyor helps feed raw material more steadily. Conveyor length, height and feeding direction can be checked according to the buyer’s site layout.
Screen or chip-size control requirements should match the downstream hammer mill and pellet line process. Final powder size is normally controlled again by grinding.
