Enhanced gravity closed spiral classifier: Experimental …
It is evident that D 50 c increased with increasing particle loading for both silica and iron ore systems. For silica, the spiral classifier had a cut size in the range of 82-108 μ m, whereas for iron ore the spiral classifier had a cut size of 38-66 μ m. Hence, there is a gap between the range of D 50 c values observed in silica and iron ore ...
