“…The proposed scale-up model built based on Equations ( 6)-( 9) is essential for improving stirred mill operational parameters and design. When the scale-up model allows for the accurate prediction of the operating parameters, it is possible to reduce the cost of the re-design of the full scale (industrial mill), and all the necessary improvements can be made on the laboratory prototype or during numerical modeling [62][63][64]. This reduces the time and cost of experiments for adjusting optimal operational parameters for grinding different materials.…”

This study examines the grinding process of pumice based on the dry and wet laboratory measurements, scale-up method, and life cycle assessment. This research’s main goal was to set up the relation between scale-up and life cycle assessment results for the wet grinding process with the help of mathematical equations. Within the first research works, basic grinding testing in a laboratory dry Bond mill was accomplished. This step allowed the description of the estimated particle size distribution, median particle size, specific grinding work, and grindability index number of pumice. The second step was the determination of power consumption and scale-up in a laboratory stirred media mill, and it involved the assessment of resources, primary energies, and environmental impacts of wet grinding using GaBi 8.0 software. According to the results, we obtain life cycle emission factors by introducing five coefficients for grinding in laboratory and industrial conditions. These constants depend on the external dimensions of the mill and can be expressed by a derived scale constant from the scale-up. Research results enable the industry to make a prognosis for industrial plants based on the integration between life cycle assessment and scale-up of the pilot grinding processes.

“…The concept of the rotarybased feeding system draws inspiration from the widely used rotary airlock feeder model, which functions as a sluice gate. The incorporation of a rotary mechanism allows for a steady and continuous flow of material 18) . By minimizing disturbances during the material feed, this system could potentially enhance the effectiveness of the separation process.…”

The performance of an Eddy Current Separator (ECS) plays a crucial role in efficiently separating non-ferrous metals from solid waste streams. This paper presents a novel approach for enhancing the performance of an ECS through the design of a rotary-based feeding system. The proposed system aims to optimize the feeding process by ensuring non-overlapping, consistent and controlled flow of material to the separator, thereby improving separation rate and overall efficiency. The design incorporates a rotary mechanism that facilitates a smooth and continuous material flow, minimizing disruptions and maximizing the effectiveness of the separation process. Experimental results demonstrate the superiority of the rotary-based feeding system. The results demonstrate the advantages of a rotary based system, showing a lower amount of material overlap and a better success rate of eddy current separation with an average value of 93.5%. More notably, the system achieved an 89% success rate for aluminum and an 98% success rate for copper. The findings of this study provide valuable insights into the design considerations for improving the performance of eddy current separators and offer practical solutions for enhancing metal recovery in recycling applications.
