Coking Coal - an overview ScienceDirect Topics

Generally, washability of LVMC coal can be improved by crushing it to smaller size. The difficult washability characteristics of LVMC coals are due to fine dissemination of mineral particles with macerals. The ash % of marketable product can be further improved by blending with prime coking coal, so that this coal can be used in various steel plants.

2017-9-1  The relationship between shear force and selective liberation of middling coking coal was investigated by crushing the coal at different shear angles (15°, 30°, 45°, 60°, and 75°). Subsequent analysis of the middling coking coal revealed that as the ash content of coal increased, the shear strength and cohesion increased, while the internal friction angle gradually decreased.
