A Cutter Head is an important component used in plastic crushing, granulating, and pelletizing machines. It holds and supports the cutting blades that cut or shred plastic materials into small pieces or granules during processing.

The cutter head rotates at high speed inside the cutting chamber, allowing the blades to cut plastic waste efficiently. It is widely used in plastic recycling equipment such as crushers, granulators, and pelletizing machines.

Main Components

1️⃣ Cutter Head Body

The main rotating part made from high-strength steel that holds the cutting blades.

2️⃣ Cutting Blades

Sharp blades mounted on the cutter head used to cut plastic materials.

3️⃣ Blade Holder

Keeps the blades firmly fixed to the cutter head.

4️⃣ Shaft Connection

The cutter head is mounted on the main rotating shaft driven by the motor.

Applications

Cutter heads are used in many plastic processing machines, including:

• Plastic crusher machines
• Plastic granulators
• Plastic pelletizing machines
• Plastic recycling systems

They are used for cutting materials such as:

• Plastic bottles
• Plastic films
• Plastic pipes
• Injection molded plastic waste

Working Principle

1. Plastic materials enter the crushing chamber.
2. The motor rotates the cutter head at high speed.
3. Blades mounted on the cutter head cut the material against fixed blades.
4. Plastic pieces are reduced into flakes or granules.
5. Processed material exits through the screen mesh.

Advantages

✔ Strong and durable structure
✔ High cutting efficiency
✔ Long service life
✔ Easy blade replacement
✔ High resistance to wear and impact
