Method for increasing resistance of chain barrel to wearing, preferably of the mining scraper belt conveyors

摘要

the increase in resistance to abrasive consumption steel drums, chain conveyors, particularly for mining zgrzebu0142owych seats cooperating with the ogniwowym undergo dynamic surface treatment in the places of cooperating with chain gniwowym and underlying teeth drum chaining.the dynamic surface treatment is performed, by spraying steel pellets, rounded, hardness from 54 to 62 hrc with intensity kulowania measured tiles almena type a, using the almena, r = 0,30u00f70,40 and the degree of coverage of at least 2x98%.
