This paper presents selected results of an analysis of damage causes to pellet mill matrix. The tested pellet mill matrix was used for the traditional technological process of pellet production. The tests were carried out since matrix failure times were found out to be too short. In order to assess the causes of matrix damage, tests of chemical composition and hardness of the matrix material were performed as well as observation of microscopic points of wear, analysis in the area of parameters of the process of operation and general conditions of use of the pellet mill. Discrepancies between the chemical composition of the material of the pellet mill and the information contained in the DTR were observed. Attention was paid to a possible influence of heat treatment and operating parameters on its premature damage.
