RESEARCH OF WEAR RESISTANCE OF MATERIAL
HAMMERS FOR CRUSHERS IN ABRASIVE ENVIRONMENT

Zaporozhe state engineering academy

The construction of experimental apparatus for research of materials in an abrasive
environment is worked out and the comparative tests of wear resistance of hammers of crushers,
made from steels 35Х2СЛ, 65ХГСЛ, 110Г13Л, 250Х25НТ, 320Х20Н and 27ХГСМДТЛ are
executed. It is reveal that the best complex of necessary properties is owned by hammers from
steel 320Х20Н.

Keywords: hammer crushers, abrasive wear, wear resistance, material of hammer,
