Analysis of Research on Improving Belt Conveyors for Feeding Raw Cotton to Stacks and Closed Warehouses
Year: 2026
Type: article
Abstract: This thesis analyzes scientific and practical work on belt conveyors that feed raw cotton to open stacks and closed warehouses. It is shown that low-grade cotton with a high content of impurities and moisture heats up spontaneously during storage (up to 70–80 °C), that impurities penetrate deeper into the fibre during transport and storage and become harder to remove, and that impact-type cleaning increases damage to fibre and seed. Foreign (US) module technology is found unsuitable for local conditions: it needs 2.5–3 times more land (400 vs. 1000 kg/m²), and pneumatic transfer consumes about 40% of the energy of a gin line. The analysis points to cleaning raw cotton directly in the conveying flow before stacking as a promising direction.
