Failure analysis of irreversible changes in the construction of rubber–textile conveyor belt damaged by sharp-edge material impact

• Cause and effect diagram of rubber–textile conveyor belt damage.
• Identification of conveyor belt zones with frequency damage.

• Record of potential and kinetic energy caused by sharp-edge material impact.

One of the most frequently damage of rubber–textile conveyor belt is caused by sharp-edge material impact. The paper deals with study of process of irreversible changes formation in the internal structure of rubber–textile conveyor belt caused by sharp-edge material impact. The aim of the paper is knowledge of damage process which is required for the correct regulation of operation conditions for conveyor belt. The aim is to determine conditions caused this type of damage (height of impact and weight of material impact). Non-destructive methods (computer metrotomography) is used for study of changes in the construction of conveyor belt. The paper presents theoretical and experimental evaluation of the process of conveyor belt damage.
