Issues of design modernization of vibrating feed grain grinders

Abstract

One of the most important factors in improving the efficiency of livestock production is to reduce the costs of feed preparation. Under modern market conditions, agricultural production is focused on energy and resource saving. Currently, the most common way to prepare grain for feeding is to grind it. The equipment for performing this operation is still so imperfect that only a small part of the total energy consumed by the machine is spent on overcoming the forces of molecular adhesion of the material to separate its pieces into parts, even in the best designs of grinding devices. Currently, vibratory jaw grinders are actively used on livestock farms, various processing plants, and feed mills. Noting their advantages, such as high productivity, manufacturability, and stability of operation, it is impossible not to highlight a number of significant disadvantages. At the moment, the range of shredding devices is quite wide and is characterized by a variety of design solutions. The choice of a specific design solution for the needs of a manufacturer enterprise depends on the goals and objectives that farmers set themselves when feeding animals. From a scientific point of view, it is of interest to modernize existing and develop new shredding devices. The research goal is to analyze the existing structures and search for promising areas for their improvement. The findings of a review of the designs of vibrating feed grain grinders developed for the fields of the agro-industrial complex are discussed. The main problems in the design improvement are considered, and the directions of research are determined.
