Disc-Type Wood Chipper Machine Overview
A Disc-Type Wood Chipper is a high-efficiency machine designed for cutting and processing logs, branches, and wood waste into uniform wood chips. It features a rotating disc with mounted blades that slice the wood into consistent chip sizes. This type of wood chipper is widely used in forestry, sawmills, biomass power plants, paper mills, and wood pellet production facilities.
The disc wood crusher occupies little space, making it popular in small biomass processing plants. We offer two types of disc wood crusher to meet customers’ special conditions. The fixed-type wood crusher is mainly used in plants or factories, while the mobile wood crusher is used in forest zones. Compared to drum-type wood chippers, disc-type wood chippers offer higher cutting precision, lower energy consumption, and better chip quality, making them ideal for applications that require uniform-sized wood chips.
Advantages of a Disc-Type Wood Chipper
1. High-Efficiency Cutting with Lower Energy Consumption
The flywheel effect of the rotating disc reduces the energy required for each cut. Uses less fuel or electricity than drum-type chippers for the same output.
2. Uniform and Consistent Chip Size
Produces high-quality, uniform wood chips ideal for biomass energy, pulp mills, and MDF board production. Adjustable blade settings allow for custom chip sizes.
3. Longer Service Life and Lower Maintenance
Fewer moving parts compared to drum chippers, leading to less wear and tear. Blades are easily replaceable, reducing downtime.
4. Portable and Mobile Options Available
Small size, allowing easy movement between processing sites.

Key Components of a Disc Wood Chipper
1. Rotating Chipping Disc (Flywheel)
The core component of the wood crushing machine, made from high-strength steel.
Houses 4-6 chipper blades that slice the wood upon contact.
The disc diameter ranges from 400mm to 1,000mm, depending on machine capacity.
2. Chipping Blades (Knives)
Made of hardened alloy steel or carbide-tipped for durability.
Number of blades: Typically 4 to 6, adjustable based on cutting efficiency and chip size requirements. The blades must be sharpened or replaced periodically for optimal performance.
3. Feeding System
Manual feeding chute: This is for small-scale biomass crushing operations.
Hydraulic or conveyor feeding: Used in industrial models for consistent feeding and reduced labor.
4. Blower Discharge System
Uses airflow to move chips into storage or transport systems.
5. Power System
It can be powered by electric motors or diesel engines. Electric models are ideal for stationary applications. Diesel models provide portability and flexibility for remote forestry sites.

Applications of a Disc-Type Wood Crusher Machine
1. Biomass Fuel Production: Converts raw wood into sawdust. Prepares wood materials for wood pellet mills and biomass power plants. Reduces wood size for efficient burning and energy conversion.
2. Paper and Pulp Industry: Produces wood fibers for paper, cardboard, and pulp manufacturing. Paper mills use uniform-sized wood chips as raw material for paper pulp production.
3. Animal Bedding and Composting: Creates soft, absorbent sawdust for poultry, horse, and livestock bedding. Crushed wood is also used as a composting material for soil improvement.
4. Forestry and Logging Operations: Forestry industries use disc wood chippers for efficient waste management by processing branches and logs into valuable products.
What Materials Can Be Crushed By This Wood Crusher?
A disc-type wood crusher can process various biomass materials. Generally speaking, it can crush tree branches and stems with a diameter of 70 mm- 250 mm and moisture content of above 30%. Many fiber stalks like bamboo, couch grass, corn, and Sorghum stalks can also be crushed to make biomass pellets. The crushed materials are particles with a diameter of about 3-5mm and can be directly used for pelletizing or briquetting.

How a Disc-Type Wood Crusher Works
A disc wood chipper consists of a large, heavy-duty steel disc with attached chipper knives that rotate at high speeds. Wood is fed into the chipper, and as it makes contact with the disc, the blades slice the material into wood chips. This wood crusher integrates a cutting and crushing function. During blade cutting, the rotator creates high-speed air and spins in the direction of the blade cutting. Raw materials speed up in the air and impact repeatedly to crush them completely.
