The Application of Similarity Theory and Dimensional Analysis to the Study of Centrifugal-Rotary Chopper of Forage Grain

This article presents the device and principle of operation forage grain crushers that use centrifugal force inertia to supply working bodies—which occurs as a result rotation rotor with vertical axis. The results some tests machines on this have been characterized. Attention is drawn disadvantages most research works, namely lack premises for creating shredders class wide range performance. aim work establish relationship between design technological parameters centrifugal-rotary shredder using theory similarity dimensional analysis. Moreover, experimental data show an empirical when calculating efficiency model considered above. By applying criteria, dimensionless complexes were obtained, which allow determine significance selected at initial stage shredder. novelty application analysis, allowed scaling obtaining higher efficiency, while maintaining quality obtained product. technique indicates energy costs grinding process, can be used select ratio in would ensure minimum amount consumed.
