What factors affect the service life of shredder cutters

Nowadays, metal shredders are used more and more widely. Everyone also knows that the shredder mainly relies on the blade to work. If the blade wears out, it will reduce the production efficiency, and the blade is in direct contact with the material. As the most important part of the shredder equipment, the service life directly affects the performance of the shredder equipment. According to the different materials shredded by the shredder equipment, the shredder cutters have different shapes and structures.

The shredder equipment is widely used in shredding wood, PE pipes, plastic bottles, waste copper wires, plastic films, woven bags, paper, circuit boards, light and thin metals, medical supplies, waste home appliances, vehicle recycling, and domestic garbage disposal Of shreds. According to the type of shredder, the cutter can be divided into: single-shaft shredder knife, double-shaft shredder knife, three-shaft shredder knife, four-shaft shredder knife, etc. So what are the main factors that affect the service life of the shredder equipment?

1. The structure of the cutter: the cutting gap between the cutters, the angle of the cutter, the surface roughness of the cutter blade;

2. The raw material of the tool: the amount of beneficial alloying elements and the content of harmful alloying elements in the material;

3. Heat treatment of the cutting tool: the hardness of the blade and the uniformity of hardness on the same surface;

4. Rotation speed of the tool: the shredding speed of the tool relative to the material;

5. The shredding force of the cutter: the power of the shredder equipment. Metal shredder blades are vulnerable parts. If the shredded materials are relatively hard, like metal products, they will wear more to the blades. Some materials are easier to shred, and the wear on the blades is relatively small.

At the same time, you can always check the condition of your own equipment according to your actual situation. Sometimes the blade becomes blunt after being used for a long time, and it only needs to be polished. There is no need to replace the blade. How should the blade be repaired and shredded? The blade grinding of the machine is not the same as others. Some mechanical blades are flat, and the shredder blade structure is quite special.
