Abstract:
It was found that the differences in the distribution of particle length were the species feature of energetic plants. The length distribution of comminuted willow particles showed the highest mean value and good regularity, while the topinambour mixture was the shortest and most irregular in the mixture of energetic plants. Connectivity between mean values of particle length plants broken up in the forage harvester and in the beater mill, calculated by geometric mean method and according to Rosin-Rammler-Sperling-Bennett model, was very high, as testified by square correlation values, which amounted to 79.4 and 97.8% respectively. The research allows proving the practical possibility of using the RRSB model to determine the amount of separated material meeting dimension requirements for production of formed fuels.
