As an important component of shredder equipment, the service life of cutting tools directly affects the performance of shredder equipment. According to the different materials shredded by shredder equipment, shredder knives have different shapes and structures. The shredder equipment is widely used for shredding wood, PE pipes, plastic bottles, waste copper wires, plastic films, woven bags, paper, circuit boards, lightweight metals, medical supplies, waste household appliances, vehicle recycling, and household waste disposal.

　　Cutting tools can be divided into single axis shredder blades, double axis shredder blades, three-axis shredder blades, and four axis shredder blades according to the type of shredder. So what are the main factors that affect the service life of shredder equipment knives?

　　1、 Structure of cutting tools: cutting gap between cutting tools, angle of cutting tools, surface roughness at the cutting edge of cutting tools;

　　2、 Raw materials for cutting tools: the content of beneficial alloy elements and harmful alloy elements in the material;

　　3、 Heat treatment of cutting tools: hardness of the blade, uniformity of hardness on the same surface;

　　4、 Tool rotation speed: refers to the shredding speed of the tool relative to the material;

　　5、 The tearing force of the cutting tool: that is, the power of the shredder equipment.
