Some Physico-Mechanical Characteristics of the Wheat Grist in the Breakage Phase during Milling Process
In the paper is presented a technological scheme of the breakage phase for a wheat mill with capacity of 200 t / 24 h and the results of the research experimental regarding the features of the grindings before and after passing through the mills with rollers. Researches have been making in SC Spicul SA equipped with the modern equipment like Bühler type. Ground material and grind product was analyzed with a sieve shaker for determine the degree of grinding. Determinations were made of specific mass and materials density to establish the growth of the area in the grind process. The paper presents graphs regarding to separation on the sieves of the sieve shaker for the five roller mills, for the breakage phase, results by regression analysis of the experimental data obtained with relationships Rosin-Rammler and respectively Schuhman and the coefficients determined by this analysis. Also, are presented the correlation coefficients of R2, which have values in the limits R20.980 for equation Rosin-Rammler and R20.945 for equation Schuhman. The results presented in the paper are important to specialists in the milling industry
