The wood chipper machine is designed to break down wood, such as logs or branches, into 20mm-40mm wood chips. It is commonly used in pulp and paper production, wood fuel processing, feed production, and wood recycling.

Wood chippers can be categorized into two types based on their working principles and structural designs: disc and drum wood chippers. With its unique blade arrangement, the disc wood chipper is ideal for processing smaller-diameter wood (50mm-300mm) and is known for its ease of operation and low maintenance costs.

On the other hand, the drum wood chipper is particularly effective for large-scale wood chipping, offering powerful chipping capabilities and efficient processing speeds, making it suitable for handling larger diameter wood (100mm-600mm) while ensuring continuous and stable operation.

The wood chips making machine is usually not used alone; it is mostly used in production lines. The back end can add a wood hammer mill crusher for further crushing into sawdust, and then it can be used for charcoal making and other operations.

Working principle of the two machines

1. Disk wood chipper: uses a flat rotating blade disk with blades mounted on it, the raw material is in contact with the blade disk and the blades cut the wood into thin slices or particles.
2. Drum wood chipper: uses a cylindrical rotating drum with blades or a combination of blades mounted inside the drum. The wood comes in contact with the blades inside the drum, and the wood is planed into thin slices or particles through the cutting of the blades.

Disc wood chips making machine

The disc-type wood chipping machine is a processing machine used to cut fibrous and lumpy biomass raw materials such as wood, bamboo, straw, etc. into thin slices or pellets. It can be made into different styles or shapes according to the customer’s requirements, as shown below.

Disc wood chipper main accessories

Its working principle is based on a flat rotating disk with blades mounted on it, where the raw material comes into contact with the disk and the blades cut the wood into the desired form by rotating.

Features of disc wood chipping machine

• The cutting method of the disk cutter usually produces smoother shavings and is suitable for applications that require a smoother surface, such as furniture manufacturing.
• Disc wood chips making machine usually has a simple structure, which is easy to operate and maintain.
• The finished product blows upward out of the material, but the size of the material can not be adjusted and is controlled at about 3 centimeters, regular and uniform.

Mobile-type disc wood chipper machine

According to the user’s needs, the machine can be customized, for example, we can add wheels at the bottom of the machine, which can facilitate customers to use this machine in different scenarios, greatly saving time and improving work efficiency.

Large capacity drum wood chipper

Drum wood chipping machine is processing equipment used to cut fibrous and lumpy biomass raw materials such as wood, bamboo, straw, etc. into fine particles or thin slices. The main design features a horizontally rotating drum (drum cutter disk) that has several sets of blades. As the raw material is fed through the opening, the drum turns to slice the wood into chips.

Drum wood chips making machine advantages

• Wood with a maximum diameter of 25-35 cm can be processed easily.
• The length of the finished pieces can be adjusted as needed.
• With 2 blades, the chipper guarantees an efficient workflow.
• The mat is crafted from wear-resistant material, and the blades are made of high-quality steel.
• Due to the way the surface of the drum is cut, drum wood chippers can cut in multiple directions on the cylindrical surface, making the planing more wrap-around and helping to produce finer particles of shavings.

Main structure of the drum wood chipper

Blade: it is made of 9 complex silicon, which is strong and sturdy and not easy to be damaged.

Blade roller: inside the machine, there are four knife rollers consisting of and supporting the blade, and the knife rollers are toothed. The material is hard and more resistant to wear.

Forced feeding device: this device is the location of the inlet, and its function is to press the wood to keep it from moving around, and to jam the wood to push it forward.
