FIELD: machine building.
SUBSTANCE: invention relates to devices for grinding abrasive materials and can be used in gyratory or cone crushers, as well as in roller mills. Device contains at least, a structural unit made with welded wear-resistant profiling, formed by a number of hard iron-chromium-carbon alloy with a Rockwell hardness of 55. In this case, alloys are made with a geometric ratio of length to width <4.
EFFECT: geometric ratio of length to width ensures free shrinkage of alloys without formation of risks.
