Therefore, in addition to provide repair according to a fixed time and frequency of accidents, some assistant judgment methods are required at runtime.

For metal crusher, some forging parts need no longer final heat treatment, so in order to obtain nice synthetic mechanical property, tempering is appropriate. For large forgings, heat treatment is used for processing eliminates stress, reducing hardness, preventing spots on the chemical composition and forgings, as well as refining forging organization.

Under normal conditions, the feeding of large metal crusher should be uniformly and evenly, so once the feeding speed has dramatic change or feeding materials are irregular, the metal crusher needs to be shut down for maintenance.
