2. Equipment problems. In the process of production and operation, the vibrating screen often causes accidents such as cracking of the vibrating screen box and beam breakage due to various reasons, which has serious impact on production. Some factories and mines cannot even compete for production due to this reason, causing serious losses.

The Failure Analysis and the Innovative Design of Hammer Head on Hammer Crusher Based on TRIZ Theory Abstract: This article analyzes the failure modes associated with the issues of easy-wearing and short service-life of hammer head on hammer crusher under load condition. The key factor of wearing is identified.

This work shows, for the first time, a systematic wear and damage analysis on a novelty roller crusher component used in the iron ore mining industry.
