THEORETICAL PREREQUISITES FOR SORTING PAPPUSES BY IMPROVED TRIBOELECTRIC DEVICE
Abstract
The article provides a brief analysis of the proposed methods for sorting raw cotton pappuses in an electric field and theoretical assumptions about the possibility of sorting them in an improved triboelectric device. The results of theoretical studies showed that raw cotton pappuses, depending on their mass and, accordingly, fiber quality, detach from the surface of the rotating loaded working body at different rotation angles. The latter allows, by correctly establishing the coordinate axis of the location of the separating surfaces, to sort the pappuses into different fractions depending on the quality indicators of their fibers and obtain seeds of guaranteed quality from pappuses with high fiber quality.
