hpgr drum corrosion detection method using special measuring gauge

The purpose of the current research was to describe the construction of a measuring gauge to measure the wear of the high pressure grinding roller drum. in the past, the wear rate was measured using unprincipled conventional methods and only using a ruler and a caliper. the obtained wear rate was not exact due to using the improper tools and human error. thus, implementation a principled method with the minimum allowed error requires making an accurate gauge. the new design includes a crown magnet base and a perforated ruler. the mentioned tool was designed and built and its corrosion rate was examined during two periods according to the obtained graph.
