The research procedures connected with the comparative study of the innovative design of the grain hammer mill at the time of barley’s seeds crushing are presented in the study. For the purpose of the study’s performance, there has been developed and constructed a test stand where the grain hammer mill differing in design of the hammer assembly - of rotor, was tested. The studies were conducted on the basis of the modern measurement apparatuses composed of a torque meter with a revolution counter MIR-20 and a two channel measuring instrument MW2006-4 connected with a computer of IBM class. Recording of the values of the measured volumes was performed with the use of a PP203 software. Having conducted a statistical analysis of the results of the experimental studies it was found that the new design solution of the grain hammer mill’s rotor was more effective than the standard one commonly used.
