Abstract (en)
[origin: EP0159710A2] The invention relates to a method for crushing material which can only be crushed with difficulty, in particular wet coal or coke, between rotating crushing bodies and a crushing track to a final degree of fineness, characterised in that the crushing occurs in a material bed on the crushing track using a high specific pressure, the material for crushing being run over repeatedly and entrained by crushing rollers between concentric, cylindrical crushing tracks of which one, preferably the inner one, is rotationally driven. <IMAGE>
