Among a number of methods for intensifying the process of grinding grain material in the technology of compound feed preparation, one of the most promising can be considered the use of a vibration field, which contributes to the formation of optimal conditions for the timely withdrawal of the finished product from the grinding zone and ensures self-cleaning of the separation surfaces from the remnants of the crushed product (especially when using non-food classes grain), thereby ensuring the maximum throughput of the machine.

Given that for grinding in feed production mainly use impact machines, which are adapted to the destruction of solid and at the same time fragile objects, as well as the economic feasibility of processing substandard feed grain, which has completely opposite physical and mechanical characteristics. scheme of vibrating-rotary disk crusher. The essence of the development is to provide a combined force on the material, namely, due to the rotational and vibratory motion of the impact elements of the crusher, a combination of impact destruction and cutting material, which will process both hard and wet material without significantly reducing equipment throughput. In addition, the oscillating mode of the working chamber and, as a consequence, the separation surface will facilitate the timely removal of the finished product from the grinding zone.

The next stage of creating a vibrating-rotary crusher, which precedes the design and constructive implementation is to perform theoretical calculations of its parameters, including using the methods of mathematical modeling.

Thus, in order to achieve high efficiency of the process of grinding feed by the designed machine, theoretical studies of the relationship between the values of kinematic parameters of the executive bodies and electricity consumption to drive them, the main results of which are presented in the article.
