Impact crusher is able to crush coarse, medium and fine materials such as granite, limestone and concrete whose feeding granularity does not exceed 500mm and compression strength does not exceed 350MPa. To ensure longer life of impact crusher, the user should have a good repair and maintenance for it.
1) Before being put into operation, impact crusher needs to inspected carefully, for example, whether fasteners is loose or not, whether wear-resistant parts should be replaced or not, whether lubrication and cooling system is ok, etc.
2) Impact crusher should be started in the sequence as follows: dust removal equipment–conveying equipment—crusher and feeder. These machines should run without load firstly, after making sure there is no abnormal condition, these machines can run with load.
3) In the process of running, you should pay more attention to inspecting lubricating system, and adding or replacing the lubricating oil regularly. The temperature of rotor-bearing should be below 60 °, the maximum temperature cannot exceed 70 °.
4) When stopping machines running, it should be according to the sequence of production flow chart, which is in contrary to the starting sequence: Feeder has to be stopped firstly, when materials in crusher is discharged completely, then main motor and final product conveying equipment system can be stopped.
