There are schemes of various vibroshakers for classification of dry materials for construction, agriculture, food and processing industry, in mining and transport, examined in this article. As a result, of the analysis the authors came to conclusion about low efficiency and reliability of known vibroshakers. In course of their functioning significant part of consumed energy is spent for bringing in movement of massive driving elements. Actually, each of these vibroshakers realizes only one scheme of loading with relatively narrow range of change of its main parameters (amplitude, frequency, transmitting energy). Besides, intensive dynamic loadings make a negative influence on supporting elements of these machines and that leads to their rapid wear. With examination of these disadvantages of known vibroshakers, authors elaborated schemes of improved vibroshakers with electromagnetic drive for classification of dry materials. The proposed vibroshakers provide complex schemes of loading of processed material and that promotes to increase of efficiency of the working process. In one of these schemes foreseen possibilities of change of location of electromagnetic vibro-exciters relatively of foundation. Later allows to change a scheme of loading of the processed material depending from its physical-mechanical characteristics. An electromagnetic drive of the improved vibroschakers gives possibility of a separate and accurate adjustment of the main parameters of the loading of material in wide range. In the constructions of the vibroschakers are absent elements of friction and massive inertia masses therefore they have an increased reliability and efficiency. There are differential equations of the movements of the executive elements of the vibroschakers are proposed in the article that allow to determine their main working parameters in course of different stages of a working cycle. These equations can be used for creation of methods of design calculation of the proposed vibroschakers.
