Plastic Granulator is a machine to crush plastic materials into small pieces, reduce the volume of plastic waste, making them easier to recycle or further process. It has high rotational speed and sharp blades which ensures smooth size reduction of plastic products in different forms. The outlet material is small and uniform pieces, it can also adjust the blade clearance and change the screen sieve to control the outlet material size. It is widely used for crushing plastic bottles, plastic pipes, injection molding runners, plastic films, plastic containers, and various post-industrial plastic scraps.

Plastic Granulator is designed to process a wide range of rigid and semi-rigid plastic materials commonly generated in recycling plants, manufacturing facilities, and waste management operations. It reduces bulky plastic waste into uniform flakes or granules that can be reused in extrusion, pelletizing, injection molding, and other recycling processes.
Common materials processed by a Plastic Granulator include PET bottles, HDPE containers, plastic drums, PP woven bags, PVC pipes, ABS plastic parts, PS products, plastic sheets, PA components, plastic pallets, plastic crates, injection molding runners, blow molding waste, automotive plastic scraps, and various post-industrial plastic waste streams.
For different material characteristics, Kowloon Machinery can customize blade configurations, rotor designs, screen sizes, and motor power to achieve optimal particle size and production efficiency. Whether processing hard plastics, engineering plastics, hollow containers, or production scrap, our Plastic Granulator provides reliable size reduction with consistent output quality.

Plastic Granulator works by cutting plastic waste into uniform flakes or granules through a high-speed rotor and stationary blade system. The machine is designed to efficiently reduce the size of various plastic materials, making them easier to recycle, transport, and process in downstream production lines.
First, plastic materials such as PET bottles, HDPE containers, plastic pipes, injection molding runners, or production scrap are fed into the cutting chamber. Inside the chamber, rotating blades work together with fixed blades to continuously shear and cut the material into smaller pieces. The processed material then passes through a screen located beneath the rotor. Only particles that meet the required size can pass through the screen openings, ensuring a consistent and uniform output. Oversized pieces remain in the chamber for further cutting until they reach the desired size.
Built with a thickened steel plate housing and reinforced frame, the Plastic Granulator offers exceptional durability, vibration resistance, and long-term operational stability in demanding recycling environments.
Manufactured from premium blade materials, the cutting knives provide excellent wear resistance and can be repeatedly sharpened, reducing replacement costs and extending service life.
The specially designed staggered blade arrangement distributes the cutting load more evenly, improving granulation efficiency while reducing energy consumption and blade wear.
Equipped with a high-performance motor, the machine delivers stable power output, smooth operation, and reliable performance for continuous plastic recycling applications.
Engineered for maximum productivity, the Plastic Granulator can quickly process a wide range of plastic materials, helping recycling facilities increase throughput and improve operational efficiency.
The combination of precision cutting and customizable screen sizes ensures consistent particle size, producing high-quality plastic flakes suitable for washing, pelletizing, and further recycling processes.
Featuring a simple structure, durable components, and a low failure rate, the machine requires minimal maintenance, helping reduce downtime and lower operating costs.
Designed specifically for plastic size reduction, the Plastic Granulator occupies minimal floor space while efficiently processing PET, HDPE, PP, PVC, ABS, and many other plastic materials.

Which One Should You Choose?
Choose Plastic Granulator when your goal is to produce small uniform plastic flakes for washing, pelletizing, or direct recycling applications. It is ideal for processing relatively clean and pre-sized plastic materials.
Choose Double Shaft Plastic Shredder when handling large, bulky, thick-walled, or difficult-to-process plastic waste. In many plastic recycling plants, a Double Shaft Plastic Shredder is used as the first stage of size reduction, followed by a Plastic Granulator to achieve the final particle size required for recycling.
A: Plastic Granulators can process a wide range of materials, including PET bottles, HDPE containers, PP products, PVC pipes, ABS plastics, plastic crates, plastic pallets, injection molding runners, and other post-industrial plastic waste.
A: Plastic Granulator uses high-speed cutting blades to produce smaller and more uniform plastic flakes, while a Plastic Shredder is typically used for primary size reduction of large and bulky plastic materials.
A: The final particle size depends on the screen size installed in the machine. Different screen configurations can be selected to produce plastic flakes suitable for washing, pelletizing, or other recycling processes.
A: Blade maintenance frequency depends on the material being processed and operating hours. High-quality blades can be repeatedly sharpened, helping reduce maintenance costs and extend service life.
A: Choosing the right Plastic Granulator depends on several factors, including the type of plastic material, feed size, required output size, production capacity, and downstream processing requirements. Kowloon Machinery can recommend the most suitable model based on your specific recycling application and production goals.
