✦ Synopsis

An apparatus has been developed to directly measure the unconfined yield strength and bulk density of consolidated-coal samples. This forms part of a research programme to develop a coal-handlability index that would predict the ease with which a coal would flow through a handling system. The new test apparatus provides a fast and simple method for determining the strength and compressibility parameters that are associated with the handling characteristics of crushed coal. Tests on four coals indicate that the new test device yields valid results. Furthermore, the speed and ease of operation of the new device make it suitable for quality control and quality assurance in plants.
