Guide: Blow bar is an important part of the impact crusher, and it is also a part that is susceptible to wear during the crushing process. According to different influencing factors, blow bar will be more or less subject to wear. When evaluating the service life of blow bar, in addition to the material of blow bar, other influencing factors must be considered.
If the service life of blow bar is abnormally short, it is usually due to the following Reasons:
1. Broken material agglomerates around blow bar counterattack area
2. The selected blow bar does not match the material to be broken
3. The setting of machine parameters does not match the application (for example, rotor speed or crushing ratio)
What are the ways to reduce the wear of blow bar?
1. Thorough cleaning every day
2. Check the board blow bar regularly to ensure normal operation
3. Regular inspection and maintenance of the entire crusher cover
4. Choose a blow bar that matches the working conditions
5. Adjust all machine parameters (rotor speed, opening gap, etc.) according to working conditions
How to install the board blow bar correctly?
1. Check the degree of dirt, and remove loose dirt on the rotor, hammer and tensioner
2. Use appropriate tools and appropriate spreaders for hoisting, such as pulleys and tackles
3. Only use the rotor with a rotor turning device (if possible)
4. It is forbidden to remove the rotor protection device
