Impact crusher is a crushing equipment with high-speed rotation and inertia. It is very important to do well normal handling and maintenance for safe operation in the long run.
Before starting, impact crusher needs to inspect the equipment carefully, for example,fasteners is loose or not,the tear and wear should be replaced or not,lubrication and cooling system is ok or not,etc.
impact crusher should start as following sequence: dust removal equipment--conveying equipment—crusher and feeder. These machines shoud run without  load firstly,after making sure there is no abnormal condition,these machines can run with load.
When stopping machines running, impact crusher should be according to the sequence of production flow chart, which is in contrary to the starting sequence: Feeder has to be stopper firstly,when materials in crusher is discharged completely, then main motor and final product conveying equipment system can be stopped.
Materials should be feeded continuously and evenly to prevent bigger material than required size and metel from being feeded.
In the process of running, you should pay more attention to inspect lubricating system, adding or replacing the lubricating oil regularly. The temperature of rotor-bearing should be below 60 °, the max temperature can not exceed 70 °;
When the final product size is too big,we should stop to check the wear pattern of hammer and impact plate, the clearance between hammer and impact plante,sealing and dust collection in workshop should be done well.
