Abstract
The provision of animals and poultry with complete feed balanced in nutrition according to productivity is one of the key conditions for additional production and improvement of livestock quality and increase of protein. An improved sunflower cake grinder was proposed based on the given grinding techniques, which eliminates a number of disadvantages typical for serial products. Taking into account huge volumes of ground fodders, the problem of improving these grinders in terms of reducing their energy consumption is quite relevant. Besides, all known grinders are not suitable for sunflower cake grinding due to its physical and mechanical properties compared to other fodders. The paper describes the motion of the prepared sunflower cake along the surface of the cutting edge of knives in the form of a curved triangle of Archimedes arbelos with saw teeth in order to obtain it in a granular form. The Russian Patent 2648392 was obtained for the proposed design of the grinder, which allows expanding functional capabilities, reducing energy consumption of the process and improving the quality of grinding sunflower cake, which cannot be made by similar technical facilities. The knives in the grinder can be adapted for different fodder, both in granulated and dispersed form due to adjustment of distance between them depending on dimensions of processed material, which perform sliding cutting thus improving the efficiency of technological process. The obtained efficiency formula of the improved grinder allows increasing it depending on its design parameters and physical and mechanical properties of the material.
