Substantiation of the Structural and Technological Parameters of the Working Body of the Milling Grain Shredder
Introduction. One of the main components in the diet of farm animals is concentrated feed, which in Russia is grinded by shredders. At the same time, in the final product, there is a high dust content, which can be reduced by using grinders with a different principle of grinding. The design of a mil...

| description | Introduction. One of the main components in the diet of farm animals is concentrated feed, which in Russia is grinded by shredders. At the same time, in the final product, there is a high dust content, which can be reduced by using grinders with a different principle of grinding. The design of a milling shredder, in which grains are crushed by cutting, is proposed.
Aim of the Article. The article presents theoretical studies of the influence of design and technological parameters of a milling shredder on the conditions of grain motion along the tooth of the working body.
Materials and Methods. The theoretical study of the developed shredder was carried out using averaged acceleration methods. The tooth surface of the working organ was studied.
Results. As a result of theoretical studies, equations describing the motion of a particle along the working body tooth surface were obtained. There has been developed a program to facilitate the process of analyzing the influence of the structural and technological parameters of the shredder on the process of particle motion along the tooth surface.
Discussion and Conclusion. There is a directly proportional decrease in the time of motion of the particle along the working body tooth surface with increasing the angular velocity. At the same time, increasing the angle leads to the increase of the time of the particle along the tooth surface. The increase of angular velocity values leads to decreasing particle displacement along the axis. At the angle of 45° displacement along the axis is 1.1‒1.5 times less than at an angle of 70°. At high angular velocities, the moving along the axis is minimal. The analysis, given the need to create a smoother motion of the particle along the helical line, shows that the most rational will be the following values: angle 70° and angular velocity of the working body 185‒206 rad/s. |
