This study explores the design and automation of a cyclone-based dust collection system, focusing on the integration of programmable logic controllers (PLCs) to optimize performance. Cyclone separators are widely used for their ability to remove large dust particles using centrifugal force. Although simple in design, their performance can be significantly improved when combined with smart control systems. This project integrates Siemens S7-300 PLCs and STEP 7/WinCC software to automate and monitor the dust removal process. The result is a system capable of reducing energy consumption, improving filtration efficiency, and ensuring compliance with environmental standards.enThesis
