Optimization of the design and material of the loosening drum during cotton primary processing

Abstract

The article discusses the improvement of a cylindrical loosening drum design for loosening and cleaning cotton raw materials, which is applied to the working surfaces of technological equipment in cotton processing plants. It focuses on enhancing the quality of cotton fiber cleaning and reducing seed damage by using a coating made of heterogeneous composite polymer material based on thermosetting plastic on the pegs of the peg drum. Furthermore, it has been established that the application of heterocomposite materials as coatings for these pegs can extend the service life of the parts due to their wear-resistant properties. One of the main advantages of the proposed material is that the use of heterocomposite coatings simplifies the process of structural repair, thereby achieving economic efficiency.
