Analysis requires a good understanding of path patterns. 4 ISO failure modes classification Terminology and the ISO classification system helps to communicate the type of damage and its possible causes. 5 Damage and actions A number of cases are described together with corrective actions. In this chapter, only non- destructive analysis is covered.
The crusher jaw had therefore failed prematurely. ASTM A 128 grade B-4 is a grade of austenitic manganese steels that combines both high toughness and good wear-resistant properties required for crusher jaws. From the spectrometric analysis, the elemental composition of the failed crusher jaw conforms to ASTM A 128 grade B-4.
Jaw crushers are utilized extensively in the industries of mining, metallurgy, build- ing materials, ceramics, and engineering of massive minerals with small and medium par- ticle size crushing [1 ...
