What are granulator knives and screens used for?
Granulator knives and screens are essential components in size reduction processes, particularly in plastic recycling and manufacturing. The knives cut materials into uniform pieces, while the screens control the particle size and prevent over-grinding, ensuring efficient processing and consistent output.
How do granulator knives and screens improve processing efficiency?
Our knives are precision-engineered to provide clean, burr-free cuts, reducing the need for reprocessing. The screens are designed with uniform hole patterns to control particle size, minimize fines, and prevent clogging, leading to higher throughput and consistent product quality.
What materials are your granulator knives and screens made from?
Our knives and screens are made from premium tool steels and alloys including D-2, CPM 10V®, CPM M4®, and Stellite®. For extreme applications, we also offer inlaid carbide, titanium carbide, and ICE™ Inlaid Carbide Extreme options. These materials provide superior wear resistance and extended service life.
What are some common causes of poor granulate quality?
Common causes include dull knives, improper knife gap, damaged screens, or incorrect rotor speed. Regular maintenance and proper setup ensure consistent, high-quality output.
Can you provide custom granulator knives and screens?
Yes, we offer tailored solutions to meet specific operational requirements. Whether it’s adapting to unique machinery or optimizing for particular materials, our custom designs enhance performance and extend equipment lifespan.
Do you offer repair or sharpening services?
We provide professional sharpening, regrinding, and refurbishment services to restore knife performance and extend overall life. Quick turnaround helps minimize downtime and maintain efficiency.
Do you provide replacement parts?
Yes. We supply OEM-compatible knives and screens for most major granulator brands, including Cumberland, Rapid, Nelmor, Conair, and others. Custom options are also available.
How can I extend the life of my granulator knives and screens?
Regular inspection and maintenance are crucial. Keep knives sharp by inspecting and replacing blades as needed, cleaning the cutting area, and ensuring proper alignment. For screens, regular cleaning and checking for wear or damage can prevent clogging and maintain consistent output.
