Plastic Shredder Blades

Crusher blades are primarily used for various types of plastic products. They come in two main types: all-steel blades and steel-tipped blades.

Materials: 65Mn spring steel, 9crsi, SK5, T10, SKD11, D2
Hardness: HRC 52-55
Features: Good impact resistance
Applications: Suitable for shredding and recycling plastic materials such as ABS, PE, and PP sheets

Types of crusher blades

Flat blade

Features: straight shape, sharp cutting.

Application: suitable for cutting softer materials such as plastics and rubber.

Hook blade

Features: The front end of the blade is bent to form a hook shape.

Application: used for cutting fibrous materials such as cloth, fabric, wood, etc.

Serrated blade

Features: There are serrations on the blade to enhance cutting ability.

Application: suitable for cutting hard materials such as metal, glass, etc.

Design and structure of pulverizer blades

Number and arrangement of blades:

According to the design of the pulverizer, the blades can be installed individually or arranged in groups. The arrangement can be parallel, staggered or spiral to achieve the best cutting effect.

Angle of the blade:

The cutting angle design has a direct impact on the crushing effect. A sharp cutting angle can improve cutting efficiency, but it may also increase the wear rate of the blade.

Blade fixing method:

The blade is usually fixed to the cutter disc or knife seat by bolts, slots or welding. The fixing method must ensure the stability of the blade under high-load operation.
