摘要：This paper reports a study of the technological process of grinding plant residues of sunflower and the causal relationships of factors that form the system of quality indicators. The necessary prerequisites for determining rational modes and parameters of the roll crusher have been devised.A prototype of the roll crusher was designed and fabricated, in which the cutting knives are arranged along the entire width of the grip in a staggered manner, with the possibility to change the angle of inclination to the axis of drum rotation in the range of 5...20°.It was established that in the case of the right-side arrangement of the cutting edge of knives, the highest total level of the percentage of crushed stems in the range of 101?150?mm with an additional load weighing 800?kg exceeded by 1.58?times the corresponding indicators of the roll with an additional load of 600?kg. The largest overall value of the percentage of crushed stems in the range of 0?200?mm when additionally loading the roll with 800?kg was 1.13?times higher than the corresponding indicators of the roll with an additional load of 600?kg.In the range of 0?200?mm, with an additional load on the roll of 600?kg, at the left-side arrangement of the cutting edge of the knives of the roll, higher total percentage of crushed stems was observed compared to the right-side arrangement. At a speed of 7.45?km/h, 13.6?km/h, the cumulative value of the percentage of crushed stems exceeded the corresponding indicators at the right-side arrangement of knives by 1.09?times, at the speed of 18.6?km/h – by 1.04?times, at the speed of 22?km/h – by 1.04?times, respectively.It has been noted that at the left-side arrangement of the cutting edge of the knives of the roll, the percentage of crushed stems in the range of 51?100?mm, with an additional load of 600?kg, exceeded the corresponding indicators with an additional load of 800?kg. At the speed of 10.08?km/h, it was exceeded by 1.9?times; at the speed of 13.6?km/h – by 1.44?times; at the speed of 18.6?km/h – by 1.96?times; at the speed of 22?km/h – by 1.99?times, respectively.
