In the competitive world of plastic recycling, efficiency, durability, and output quality are paramount. ASG’s plastic granulator, often referred to as a crusher, is specifically engineered to transform whole PET plastic bottles into small, uniform pieces known as PET flakes. Integrated within a PET bottle washing line, this machine is a cornerstone for operations aiming for high purity and throughput. With advancements in wet granulation technology, ASG Machine ensures that your investment not only meets but exceeds industry standards, providing a reliable solution for recyclers, manufacturers, and international traders.
How ASG’s Plastic Granulator Enhances Your Recycling Line
ASG’s granulator employs a wet process, where a dedicated waterline continuously sprays water into the cutting chamber. This design offers two significant advantages:
- Partial Cleaning: The water aids in washing the PET flakes during the size reduction process, removing contaminants and improving material quality early in the recycling line.
- Heat and Friction Reduction: Acting as a lubricant, the water minimizes friction and heat generation within the chamber. This not only protects the integrity of the PET flakes but also substantially decreases the frequency of knife sharpening—by two to three times—leading to lower maintenance costs and less downtime.
Technical Mechanism: The Science Behind the Cut
At the heart of ASG’s granulator is a robust open rotor system, equipped with knives arranged in a double-angle or v-shape configuration. Powered by a high-torque electric motor, this rotor spins at elevated speeds within a chamber fitted with stationary knives.
As PET bottles are fed into the granulator, the high-speed rotor knives interact with the stationary blades, creating a precise scissor-cutting action. This method ensures consistent and efficient size reduction. The material is continually cut until it meets the size specification and passes through a sizing screen at the chamber’s base, resulting in uniform PET flakes ready for further washing and processing.
Built for Durability: Knife Quality and Maintenance
Knife wear is a critical factor in granulator performance. ASG addresses this by using only premium SDK11 steel (equivalent to D2 steel in the U.S.) for all rotor and stationary knives. This high-carbon, high-chromium alloy offers exceptional wear resistance, extending operational periods between sharpening.
Our standard model includes 15 rotor and 4 stationary knives, all designed for easy adjustment and replacement. Hydraulic-assisted access to the cutting chamber simplifies maintenance, reducing labor time and enhancing overall productivity.

Frequently Asked Questions (FAQ)
Q: What is the difference between a dry and wet granulator?
A: Dry granulators operate without cooling agents, which can lead to higher heat generation and more frequent knife maintenance. Wet granulators, like ASG’s models, use water to cool and lubricate the cutting process, reducing heat and extending knife life.
Q: How often do the knives need sharpening?
A: With ASG’s wet granulation system and SDK11 steel knives, sharpening frequency is reduced by two to three times compared to dry systems. Depending on usage, knives may require sharpening after several hundred hours of operation.
Q: Can the granulator handle other materials besides PET bottles?
A: While optimized for PET, ASG granulators can process other rigid plastics. Consult with our team to ensure compatibility and optimal settings for different materials.
Q: What kind of maintenance does the granulator require?
A: Regular maintenance includes checking knife sharpness, ensuring the water spray system is clean, and inspecting the motor and drives. Hydraulic-assisted access makes routine checks straightforward.
Q: Are custom output capacities available?
A: Yes, ASG offers custom-built granulators for operations requiring higher or unique output specifications. Contact us with your production needs for a tailored solution.
