The obtaining of granules with given sizes from clay powder in a two-section disk granulator with coaxial sides under the impact of drops of a binding liquid of the same diameter was studied. Optimum granulation time was determined in the first section with excessive powder and in the second section without powder contributing obtaining of round granules with sphericity of not more than 0.850 and similar granulometric composition. It was established that the value of formed granules is determined with the size of fed drops of binding liquid, strength increases with the rise of their diameter. However, as the diameter increases density limit decreases. It was shown that initial stages of granulation process have the greatest impact on potential mechanical strength of granules. Dependence of drop size of a solution to obtain granules of a given diameter was determined
