Recommended practices in coal crushing are: (1) incorporation of a screen to separate fines and small particles to avoid extra fine generation in crushing, and (2) incorporation of a magnetic separator to separate iron pieces in coal, which may damage the crusher. Sample preparation includes drying (in air), as well as crushing, dividing, and ...
