Abstract

The study investigates the effectiveness of an improved RAMDARS system in reducing the environmental impact and carbon footprint associated with coal and lignite utilization. The RAMDARS system, which uses radiometric detection and automatic removal of stones from coal/lignite stream, has been optimized using Variable Frequency Drives (VFD), the Internet of Things (IoT), and a vibrating crusher. The study evaluates the performance of the optimized RAMDARS system in terms of quality improvement and reduction of environmental impacts, as well as its economic feasibility. Results indicate that adopting VFD, IoT, and vibrating crusher has significantly improved the efficiency of the RAMDARS system in removing pyrite from lignite. The system can now effectively remove pyrite of all sizes and types, a significant improvement over the previous system limited to removing only larger pyrite particles. The improved RAMDARS system has several economic and environmental benefits, such as reducing carbon dioxide emissions and other pollutants and lowering transportation costs and energy consumption. This study contributes to developing more sustainable and efficient coal and lignite utilization technologies, with significant implications for the mining industry.
