The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...

For slurryfed entrained flow gasifiers there is a tradeoff regarding the grindability of a coal; a higher solid concentration with a coarser coal slurry may be produced, but larger particles will not gasify as well as smaller particles (Collot, 2006). Apart from milling and grinding, the hardness of a coal is not very relevant for gasification.
