The research objective was the explanation of the mechanism of interaction and the influence of the com-plex of constructive and regime parameters of the unit on crushing of tubers of potatoes on technical characteristics on a ready-made product. The systematization of indica-tors of the work of installation on crushing of tubers of potatoes is executed: directing, derivatives and resulting indicators of its functioning are allocated. On the basis of developed and patented design of the grinder of tubers of potatoes and preliminary statistical analysis of experi-mental data on its functioning systematization of indica-tors of working process was executed. As operating indi-cators served the frequency of rotation of conical shaft which had average value of 215.086 min.-1 (at a standard deviation of 25.711 min.-1), the frequency of rotation of the crushing drum - 380.104 min.-1 (at 39.011 min.-1), the step of installation of knives on crushing drum - 51.6921 mm (at 14.9737 mm), tilt angle of knives on the crushing drum has average value 7.6667 degrees (at standard deviation 6.8694 degrees). As resulting opera-tion cycle frequency characterized by the center of dis-persion of 12.042 min..-1 (at a standard deviation of 4.284 min.-1), the productivity - 795.3508 kg/h (at 290,8860 kg/h), specific power costs of the drive of con-ical shaft - 0.5087 W×h/kg (at 0.2075 W×h/kg), specific power costs of the drive of the crushing W×h/kg reel 0.4334 (at 0,1571 W×h/kg), thickness of potato slices had average value of 5.0244 mm (at standard deviation of 0.6413 mm) were chosen. Offered analytical ap-proach explained the mechanism of interaction and in-fluence of frequency of rotation of conical shaft and crushing drum, step and tilt angle of knives of the drum of installation on crushing of potatoes on changes of frequency of production cycle of processing of raw ma-terials, the productivity and specific power expenses of the equipment, and also at the size of thickness of ready potato slices. The calculation procedure can be used in predictive purposes as relative error of approach does not exceed 6.72 % in all five presented dependences (functions), and determinacy degree for everyone it is higher than 95.10 %.
