The aim of the study is the reliability of feed mill´s improvement by the study of hammer´s design parameters and the choice of the materials for its manufacture. The object of study is the process of the hammer´s wear in a feed mill of the hammer type. The results of theoretical re-search to improve the wear resistance of feed mill hammers´ are given. Analyzing feed mill work, we came to the conclusion that the hammer deviates from the radial position to the corner α. Theoretical calculations found that to avoid grain´s slipping on a hammer of a feed mill, a hammer with known cutting edge´s angle of 16-18º must be manufactured.
