For a uniform distribution of mineral fertilizer on sowing openers by main distributor it is necessary, firstly, to ensure a stable distribution law of particles in a cross-section of material supply tube on the input to a working body. Then propose a mode for dispersion of loose material with stable characteristics. The first problem is solved by introduction of a turn (bow section) in transportation tube, and the second problem by installation of quadruple helical spiral with linear shift of the beginning of winds as a whirler in a stream of moving material. The shifts of winds’ beginnings and velocities of particles are theoretically justified in horizontal transportation sites, at bow section (turn on 90˚), in a whirling zone and in a vertical section - before a dividing head which serve for calculation of their design data.

Key words: main distributor, material supply tube, mineral fertilizers, helical spiral
