China Plastic Crusher Blade Granulator Grinder Knives

Plastic Crusher Granulator Grinder Blades Knives

Plastic crusher blade plastic granulator grinder knife is used for blades of crushing on the crusher, divided into moving knife and fixed knife and a blade model, a variety, and a variety of high-quality steel, with good sharpness and wear resistance. Mainly used in plastics, rubber industries, etc. It needs to be suitable for the selection of chemical components of the blade material of different objects. It requires a suitable blade angle, both maintenance of the sharp edge, and makes the crusher blade have a certain strength and is not used in use. It requires a good heat treatment process to achieve a suitable hardness and small inner stress of the blade, and the plastic crusher blade is not deformed during use.

What is plastic crusher blade?
Plastic crusher blades are precision cutting tools installed in crushers, granulators, and shredders to shear and tear plastic waste into uniform particles. Each blade set pairs rotating moving blades with stationary fixed blades that work in tandem to cut material efficiently. Performance depends on three core factors: blade material chemistry matched to the specific plastic or rubber being processed, blade angle and edge geometry engineered to maintain sharpness under load, and controlled heat treatment to achieve optimal hardness while minimizing internal stress and thermal deformation during continuous operation. WANROOETECH PNSB series blades are manufactured from premium tool steel and processed through vacuum heat treatment followed by deep cryogenic treatment, delivering exceptional dimensional precision, wear resistance, and balanced strength and toughness. Two blade types serve different applications: paddle-type blades handle soft flexible materials like plastic films, woven bulk bags, and aluminum foil laminated bags, while claw-type blades tackle rigid dense materials such as plastic drums, bottles, thick-walled pipes, and rubber tires. All blades are compatible with major grinder, shredder, and granulator brands, with material selection and heat treatment protocols customized to each customer’s feedstock and production requirements.

PNSB Series Blade Technology

WANROOETECH PNSB series plastic crusher blades are manufactured from premium tool steel and processed through advanced vacuum heat treatment followed by deep cryogenic treatment. This dual-stage process delivers blades with exceptional dimensional precision, outstanding wear resistance, and an optimal balance of strength, toughness, and edge retention.

Two types of plastic crusher blades:

Paddle-Type Crusher Blades are designed for processing soft and flexible materials. They perform reliably when crushing plastic films, woven bulk bags (FIBC), aluminum foil laminated bags, and other lightweight, pliable feedstock.

Claw-Type Crusher Blades are engineered for tougher, more rigid materials. They excel at breaking down plastic drums, bottles, thick-walled pipes, rubber tires, and other dense or impact-resistant objects.

Our crusher blades are compatible with grinders, shredders, and granulators from all major manufacturers. Based on your material characteristics and production requirements, we select the most suitable blade material and apply a comprehensive heat treatment protocol to maximize durability and minimize replacement frequency.
