Abstract (en)
[origin: US5054694A] The invention relates to a method and to apparatus for crushing material for grinding, in which the material for grinding first of all passes in multiple circulation through a grinding stage which operates on the pressure crushing principle and then without further grinding is delivered to a classification stage consisting of two classification assemblies set to different degrees of fineness, the streams of fines from the two classification assemblies being mixed together. By the combination of these two measures a desired flattening of the particle size distribution of the end product is achieved.
