In this paper is presented a technological scheme of the breakage phase for a wheat mill with capacity of 200 t / 24 h and the research of the experimental results related to the grindings features before and after passing through the roller mills. Researches have been made at SC Spicul SA, equipped with modern B?hler equipment. Ground material and grind products were analyzed using a classifier with sieves, in order to determine the degree of grind. Determinations were made on specific mass and materials density, to establish the increase of the area in the grinding process. Graphs are presented regarding the separation on the classifiers sieves for five roller mills, for the breakage phase results by regression analysis of experimental data obtain with Rosin-Rammler relationship and coefficients determined by this analysis. In the paper are presented correlation coefficients of R2, which have values in R2 ? 0.980. The results presented in the paper are important to specialists in the milling industry.
