An operational model for a spiral classifier - ScienceDirect
2016.5.15 A semi-empirical model is proposed to account for these operating variables. Spirals are gravity concentrators used for the valorization of coal and heavy minerals. Coarse hematite iron ores in Canada are usually concentrated by spirals. Spirals classify the particles according to their size and specific gravity.
