ARTICLE ANNOTATION

quote
The article presents a theoretical analysis of the impact mechanism of a wire-brush drum in the process of delinting cotton seeds to remove delint. The movement of the seed flow along the wire-brush drum and the distribution of external forces acting on it, including normal pressure forces and friction forces, were mathematically modeled based on Euler’s equation. The study determined the dependence of the normal pressure force on the distance between the wire-brush drum and the mesh surface, as well as on the rotational speed of the drum. Through graphical analysis conducted using Maple software, the influence of various parameters on the normal pressure force was thoroughly examined. The results obtained indicate that a rational selection of constructive and technological parameters, such as the distance between the mesh surface and the wire-brush drum, as well as the rotation speed of the wire-brush drum, allows reducing mechanical damage to seeds and effectively separating short fibers. This is an important factor in preserving the natural properties of the seeds and preparing them for use as planting material. This scientific approach contributes to increasing the efficiency of seed delinting processes and the development of energy-efficient technologies. Therefore, the results presented in the article are of practical importance for industry and can serve as a basis for the development of improved technologies.
