Abstract

The article presents preliminary results of determining the coefficient of relative abrasiveness of various bulk materials. Comparative analysis of the early works of famous scientists devoted to the determination of the intensity of abrasive chafe by coal particles, crushed in mills to a size of 100 microns and less, or formed during their combustion by ash particles (the same or smaller size), usually moving in an air stream or smoke gases. It should be noted that in these studies, the abrasiveness of the material was determined indirectly - through the intensity of erosive chafe, without directly determining the abrasiveness of the material itself. There were practically no data on chafe by particles with sizes corresponding to crushing, interacting with the surface of elements, in the absence of carrier air or other gaseous substance.
