The productivity of farm animals largely depends on a balanced diet. The mineral components, introduced into the feed in small quantities are of particular importance. The uneven composition of these materials does not favorably affect the uniformity of the entire mixture. To solve the problem, a hammer grinder with some design features was designed and manufactured. For a stable outflow of mineral material into the grinder, a theoretical dependence was obtained, which made it possible to find the value of the outflow coefficient. The hydraulic radius of the outlet openings of various shapes were determined, and on the basis of this, the optimal shape of the loading window was determined. Experimental studies were carried out on table salt as a representative with changing physical and mechanical properties. The results of the study made it possible to obtain the dependencies of the influence of the grinder performance on the grinding module and the energy intensity of the process. The influence of the angular velocity of the rotor on these parameters was also revealed.
