Analysis of influence of different types of separators on fine grain coal class enrichment process in respect with qualitative and quantitative analysis of separation products

The Article presents comparative analysis of enrichment process of coal slurry that was conducted with use of different types of spiral coil separators and with consideration of influence of separators construction differences on obtained separation products. The best quality was achieved with feed material density of β=300 g/cm³ for both spirals with ash content of λi= 12,86% for Reichert LD4 and 2,85 λi= 12,86% for Krebs spiral.
