A REFLUX™ Classifier was used to classify a silica feed (0–710 µm) based on particle size. Split Fluidisation was used to generate remarkably sharp separations involving solids throughputs of up to 92 t/m 2 /h. This work builds on the previous study by Starrett and Galvin (2023) but with a focus on coarser separations at higher throughputs. As the separation size increased, there …
