The purpose of the study – is the equipment improvement for dry mixing of crumbled feed with substantiation of de-sign and operating parameters. The use of complete feed mixtures is possible only with the use of special techno-logical equipment – feed mixers, producing mixture homogeneity meeting livestock requirements. The costs of pur-chasing, operating and maintaining mixers ultimately affect the cost of livestock production. Accordingly, it is neces-sary to aim efforts at the reduction of these costs. This can be achieved by reducing the specific energy costs for the mixing process, which largely depend on the mixer design, its working parts operation and the efficiency of the mix-ing process and power consumption needed for mixing process. No method of power consumption estimation of mixers with combined working parts according to theoretical studies obtained, having alternating in regard to exe-cution and purpose areas. Power consumption needed for the mixing process is one of the main components of the operating costs for the mixing equipment, ultimately determining the specific energy costs for the mixing process – is one of the important specification of any mixer. The research methodology provided a theoretical basis for the relationship of the mixer parameters on the power consumption during mixing process. Equations for determining the power consumption for the parts were submitted in regard to auger conveyor, the first and the second transport-ing and throwing blades. The expression for determination of power consumption for mixing process from the an-gle of installation mixing and transporting blades, the filling ratio of the mixer and the frequency of rotation of the working parts have been received. The obtained and given expressions allow to determine the power values for the mixing process with an error of no more than 5%, with the values of the studied parameters of the mixer within the boundaries of the experiment.
