INTERACTION OF RAW COTTON WITH INTERNAL STRUCTURAL ELEMENTS OF DRUM DRYERS

Аннотация

This research focuses on the study of the interaction between raw cotton and the internal structural elements of drum dryers. A system of equations is presented to analyze the equilibrium of raw cotton clouds on the surface of the blades and the annular layer, determining the conditions for clod sliding or rolling. The conditions necessary for the formation of an annular layer of raw cotton inside the dryer are established. The mechanism of twisting of fibrous bonds during the rolling of excess raw cotton along the annular stand inside the dryer is examined. Examples of the calculation of fibrous bond twisting between cotton balls are provided, and recommendations are developed to mitigate ignition risks in drum dryers. KEYWORDS The annular layer, determining the conditions for clod sliding or rolling.
