In a recent project, NiaFlow was employed to simulate and optimize the mineral processing workflow for a pelletizing plant. The primary objective was to streamline the processing of limestone, among other materials. This case study highlights the application of NiaFlow’s advanced simulation capabilities in streamlining operations, enhancing efficiency, and reducing operational complexities.
Project Overview
The pelletizing plant, with a focus on limestone processing, aimed to achieve a total throughput of 140 tonnes per hour (t/h). The process flow incorporated several critical components, starting from an Aero Cyclone leading to a Silo for limestone, integrated with a fines return mechanism. Dust control was managed via a Bag House, followed by the preparation of a molasses-water mixture, essential for the pelletizing process.
A key step involved the use of two Rotary Valves, ensuring the controlled flow of materials at different stages of the process. This was complemented by a Screw Conveyor and a Mixer, facilitating the seamless mixing of limestone with other ingredients. A Pelletizing Disk was utilized for the formation of pellets, which were then forwarded to a Fluidized Bed Dryer, achieving the target throughput while maintaining the desired moisture content and pellet integrity.
The process concluded with a screening step, using a Cured Pellet Screen to ensure quality control before packaging the final product. This entire workflow was meticulously simulated and optimized using NiaFlow, showcasing its robustness in handling complex mineral processing operations.
