the amount of abrasion is mainly determined by the magnitude of the relative hardness of materials in friction. In the case of a coal particle in friction against the YGP tester blade, abrasion of the mineral inclusion is defined as /h h i b where h i and h b respectively represent the mineral particle hardness and the blade hardness.

Aug 10, 2016· A tumble strength test measures two mechanisms of feedstock degradation, that is, the Tumble Index (TI) and the Abrasion Index (AI). It was carried out following the International Standard ISO 3271:1995(E) for determination of Tumble Strength for iron ore . Precisely, a 15 kg test block sample was tumbled in a circular drum rotating at 25 rpm for 200 revolutions.
