:: Laser Scanning for Liner Management Improves Safety and Profit


Grinding mills are often the largest capital item to be purchased for a minerals processing plant. Consequently, there is a strong industry impetus to maximise grinding mill production as a means to maximise profitability and return on investment. Investigations indicate that comminution consumes more than half of all power generated on mine sites globally {www.ceecthefuture.org/why-smart-companies-are-focusing-on-comminution/} and grinding mills typically represent the majority of that energy consumption. Consequently optimising energy use in a grinding circuit is often also what’s best for the bottom line.

Safety continues to be a major issue in mining and minerals processing. Grinding mills and the mill relining process in particular represent several hazards including the presence of MV power, pinch points, confined spaces, elevated loads and manual handling. Laser scanning condition monitoring allows 100% inspection of exposed liners in a fraction of the time required for conventional inspections and can eliminate the need for confined space entry.

The data acquired through 3D laser scanning can be processed in many ways. Basic outputs might be liner life prediction and lifter profile tracking. However this analysis can become very powerful when it is correlated with metallurgical performance of the mill or circuit in question.
