Abstract

Failure of production tool components is undesirable for several reasons, one of them is economic because it can increase maintenance cost. Drag chain conveyor is one of the important tool which is used for coal handling in cement industries. The problem that often happens is  failure of chainlink.

This paper is aimed to analyze the characteristics of chainlink's fracture. Material examination which have been done is frctographic test for fractograph analysis.

The result showed that overload was the root cause of failure. Overload that indicated by dimple rupture mode on its fracture apperence was caused by jam of chainlink movement on its way. In addition, low quality of surface finish introduced so many stress raiser and unfortunately severe wear also contributed to reduce its strength.
