The object of the study is to determine the required power leveling device grinder-mixer-dryer. When operating equipment that combines grinding, mixing and drying in one device, there are such problems as energy intensity, the lack of calculation formulas for the theoretical determination of the required power, which makes it difficult to plan the energy intensity of the equipment. As a result of the research, a constructive-technological scheme of the grinder-mixer-dryer equipped with a leveling device was developed. The leveling device, rotating in opposite directions, moves the raised fodder mass to the end walls of the bunker. The operation of the screed tines eliminates excessive forage lift and speeds up the mixing process by moving the forage evenly across the entire width of the bin. The acceleration of the drying process of wet food is explained by the fact that new portions of wet food are constantly exposed to hot air. As a result of theoretical studies an analytical expression was obtained to determine the required power for the process of leveling the layer of forage mass and the required power for the process of leveling the layer of forage mass N_Т=0.286 kW was determined. The results of the experimental determination of the required power for the process of leveling the forage mass layer showed the following value N_Е=0.273 kW, i.e. the difference between theoretical and actual value is only 4.76 %. This proves the reliability of the obtained analytical expression, which provides the definition of the main parameter of the grinder-mixer-dryer, i.e. required power leveling device. The proposed device and the resulting analytical expression can also be used in feed mixers.
