THEORETICAL BASIS OF FRACTOGRAPHIC STUDY OF THE WORKING CHAMBER OF A LINTER UNIT

Аннотация

In this paper, a fractographic study of the working chamber of a linter unit and its key component, the agitator , was conducted . The purpose of the study was to analyze wear, cracking, and damage that occur during operation of the unit during the lintering of cotton raw materials. The study showed that the main destruction mechanisms are abrasive wear and fatigue failure caused by friction between the chamber walls and the cotton raw materials, as well as dynamic loads associated with the rotation of the agitator . Based on the data obtained, recommendations are proposed to increase the service life of the equipment by improving materials and optimizing the design. The results of the study can be used to increase the efficiency of linter units and improve the quality of cotton processing.
