BS ISO 12900:2018,Hard coal — Determination of abrasiveness.
This document can be downloaded here.Thank Tom from England for sharing it.
BS ISO 12900:2018 describes a method for determining the abrasiveness of hard coal.
The abrasiveness of coal is recognized as a factor in coal operations, from mining to utilization, requiring
a standard method of measurement and evaluation as some coals are more abrasive than othersThe interaction between coal and conveying, storage, and crushing equipment results in component wear. In particular, higher contact pressures in some coal pulverizers result in significant wear.
Abrasiveness as determined by this document might be of value in providing an initial estimate of the
likely wear in other applications, giving the relative effect of different coals.
