Planning and Design of Hard-Coal Preparation Plants

 · In steam-coal preparation plants the maximum feed grain size is usually 200 or 150 mm while in coking-coal plants it is 100 50 or 30 mm. Factors governing the choice of selective or non-selective crushing of coarse classes of raw coal are the required yield of coarse fractions stone content in the coarse fractions and the differences between hardness of coal and stone.

Enhancement of coking potential of coals with improvised

 · Coals with vitrinite reflectance (Ro) greater than 1 when processed using CSC showed greater improvement in coke properties as compared to coals with less than 1 Ro. Coal blend cost reduction can be effectively obtained if CSC technology is used by increasing the portion of poor coking coal by replacing good coking coals.
