Abstract

Apron feeder is one of stages in crushing circuit to convey material in short distance. Pan flight is the main component of apron feeder that is severely exposed to wear mechanism due to its direct contact with open cut abrasive ore. With this operating environment of apron feeder, regular maintenance and inspection must be conducted to assess wear rate of pan’s surface to maintain equipment availability and provide information and sign before the equipment undergoes severe and sudden degradation. 3D laser scanning is method used in this study as Non-Destructive Testing (NDT) based inspection. The aim of using 3D scanning is to model the actual condition of pan and give measurement of wear. Later this scanning data is analyzed for forecasting life prediction of when pan surface reaches its safe minimum thickness. Utilizing 3D scanning for wear measurement offers comprehensive analysis, precise measurements with visualization capabilities and handling geometries effectively. Life prediction derived from this analysis can be used as decision making to determine next replacement date of pan feeder using regression model and linear calculation. Results after four times conducting this inspection with four months period consistently, showing that the safe replacement time will be on the earliest second trimester of 2024. This provides an advantage on the shutdown planning side to prepare resources and timetable early and effectively.

Abstract

Chutes are critical materials handling assets to transport solid particles from one process step to another in mineral processing, coal mining and cement industries. The material transport, because of material characteristics, cause severe wear on internal lining of chutes or bins’ structure. The wear problem on internal lining of bins or chutes needs to be checked to keep production efficiency. Therefore, not checked wear rate causes liner replacement schedule becomes unpredictable. It leads to production loss and highly cost maintenance in industry. This study shows that condition-based maintenance through regular thickness measurement using Ultrasonic Transducer (UT) to predict life service of critical liners prevent unplanned maintenance schedule. Data collected can be used to predict the next liner replacement schedule, cuts unplanned maintenance and breakdowns.
