The shredder blade is one of the important accessories on the shredder. Its quality directly affects the machine's waste processing cycle. The shredder blade is widely used in the crushing of large-volume waste such as metal, circuit boards, plastics, waste rubber, and wood. The quality of the shredder blade directly affects the machine's waste processing cycle. According to the classification of shredders, shredder blades are divided into single-axis shredder blades and multi-axis shredder blades. As an important shredder tool on the shredder, according to the classification of the shredder structure, the shredder blade can be divided into single-axis shredder blades (square blades) and multi-axis shredder blades (including double-axis shredder blades and four-axis shredder blades).
Common materials for single-shaft shredder blades are SKD-11/DC53/D2/Cr12M0V/9CrSi. According to quality, Cr12MOV single-shaft blades have the highest cost-effectiveness. After vacuum quenching, their hardness and wear resistance are higher than ordinary materials, and the hardness reaches 60-62HRC, which better exerts the physical properties of the material and greatly improves the service life. The moving knife has 4 cutting edges, which can be rotated 90 degrees after wear and continue to be used. It is mainly used to shred waste materials such as wood, rubber, plastic, and paper. Compared with multi-shaft shredders, single-shaft shredders have a more complex design, but the replacement of the knife die is more convenient. The blade of a single-shaft shredder can be easily replaced by removing the fixing screws, while a multi-shaft shredder needs to disassemble the entire casing and remove the shaft before it can be used. Therefore, in terms of the convenience of replacing the knife die, it is easier to maintain than a double-shaft shredder.
Issues to be noted when using
1. Ensure that the machine is normal
If you want the single-shaft shredder blade to work properly, play a strong cutting effect, and create precise working standards and effects, you must first ensure the normality of the shredder. Therefore, a very important item before we work is to conduct a comprehensive inspection of the shredder, especially the safety performance of some important operating parts, especially whether the lubrication effect of claws, hammers, blades, etc. is normal, because these are directly related to the normality of the shredder.
2. Master the blade and temperature of the shredder during use
In the process of using the shredder, our construction personnel must have high professional skills. Sometimes they have to operate the shredder blade very carefully. If the blade is found to be blocked or problematic, it should be stopped and cleaned in time. Replace the blade to ensure the normal operation of the work. When the machine is overloaded, the machine temperature is too high and the waste will be ejected. At this time, obstacles should be removed in time.
3. Pay attention to details after troubleshooting
When we encounter problems with the shredder and deal with them accordingly, we do not add materials immediately, but let the blade of the single-shaft shredder idle for a few seconds. If the machine is damaged by adding materials immediately when the speed is too low, then it will not be possible to start the machine at will. If the speed is too fast, the temperature will rise and it will explode.
4. It is very important to strengthen and check the blade during work.
When our cutting work is carried out for a long time, we must pay attention to regular parking to strengthen the strength of the blade and power machinery. Avoid unnecessary accidents. If it is a long-term assembly line operation, the blade of the single-axis shredder must be placed on the machine base, so that the work is more stable, more convenient and safer. Therefore, only when the blade edge is found to be blunt or cracked, curled, opened, etc., it is necessary to replace the blade in time to ensure the smooth completion of the work and high-standard cutting effect.
