Metal shredding machine is mainly used to break scrap metal and increase its density for transportation and recycling. The equipment is widely used to deal with paint drum, diesel drum, thin iron sheet, automobile shell, metal press block, metal sheet scraps and other scrap metal materials. But the metal shredding machine blade belongs to wear parts, often used will produce wear, so we generally use high strength alloy steel, wear resistance, high strength, but when we use, some things still need to pay attention to:

1, the size of the knife Angle will affect the service life of the tool. We know that the Angle of the blade of the shredding machine can be adjusted to convert, usually between 19-23 degrees, so we can choose to adjust the needs of different cutting materials in the process of cutting, but in the selection process, the smaller the Angle is sharper, the better the cutting effect, but its defect is to reduce the service life of the tool, this will also be a combination of advantages and disadvantages.

2. Sharpening the knife can also affect the service life of the tool. Because the current shredding machine knife blade has the whole steel type round blade and insert steel blade, they have their own advantages, but the better the material of these blades, the more reasonable the alloy, the higher the hardness and wear resistance, the more prominent the high temperature resistance, the longer the service life, so many enterprises attach great importance to the choice of tool material to greatly improve the performance and service life of products.

3, the material of cutting items is very affect the service life of shredding machine tools. The same material of shredding machine tool in the process of cutting different items in the service life of the obvious difference, take cutting paper and metal two kinds of articles, because the hardness of paper than metal difference, so cutting paper tool than cutting metal service life that is too long, so different cutting material directly affects the service life of the tool.

4. The maintenance degree of the use and maintenance also affects the service life of the tool. We know that any tool that we only use without paying attention to maintenance will greatly shorten its service life, but if we learn to use it properly. Effective maintenance can greatly extend its service life.
