Wear analysis to extend life of coal chute liners

Overview

• Coal chute liner plates
• Used in primary stage crushing
• Assessment from new to obsolescence

Analysis strategy

• 6 weekly interval scans
• 12 chute scans per day
• Report deliverables blue/green/red map

In conjunction with the customer, 7D Team developed the process, procedure and methodology to provide continuous wear monitoring statistical data that could be used to asses and predict wear characteristics, with a view to prolonging the life of the chute liners.

The report format process was developed into an easy to read visual report. An indicator format (blue/green/red map) was automatically generated, so that in many cases, the reports were available in HTML format before leaving site each day.

 Each report has been tailored so that subsequent scanned data of the same liner can be overlaid, showing wear characteristics over time. Report accuracy is within 0.02 (or 20 microns).
