The multi-axis shredder blade is a claw knife, which is installed on a dual-shaft or four-shaft shredder according to the design of each company. It can generally be divided into 3-claw shredder blades, 8-claw shredder blades, and 12-claw shredders. Blades, etc., are used for crushing, shredding and extruding to reduce the size of materials. This shredder blade is used for crushing waste plastics, waste rubber, wood and other large-volume wastes.

The shredder blades are generally made of 55SiCr and H13K, which are suitable for shredding paint buckets, scrap steel, wood, scrap furniture, high-hardness plastics, etc. Cr12MoV and SKD-11 are cold work die steels. The properties of these two materials are similar. The tools made of this material have high hardness but are relatively brittle. They are suitable for soft waste materials such as rubber, fiber, and paper.

Commonly used shredder cutter specifications range from 200mm to 700mm in diameter and 20mm to 100mm in thickness. Most of the inner holes are hexagonal. They can also be made into octagonal or circular (with keyway) according to customer needs. The shredder blade adopts salt bath furnace quenching and vacuum furnace quenching, which can make the hardness of cutting tools of various materials and specifications meet the requirements.
