Abstract

Livestock farming is one of the important sectors of Uzbekistan that provides food. An integral part of livestock farming is feed production. Grinding grain is a very important stage in the preparation of complete feed. The study aims to justify the hammer’s width and theoretically investigate the parameters for grinding grain. Technical mechanics fundamentals were used in theoretical investigations. There is a schematic showing how the grain is ground in the grinding chamber. Theoretical studies indicate that for grain crushing, the internal loading resulting from grain particle compression should exceed the grain loading strength limit. According to the analytical relationship analysis to determine the width of the crusher, the width of the crusher depends on the strength limit and modulus of elasticity of the grains, the radius of rotation of the crusher, the number of blows and the diameter of the hole of the grinding chamber. In order to ensure that the grains are crushed at the required level, the width of the crusher hammer is greater than 1 cm, the radius of rotation is 21.5 cm, the number of blows is 25 times, the diameter of the hole of the grinding chamber is equal to or less than 0.0019 m.
