Abstract: The invention relates to a method and to apparatus for crushing brittle material for grinding, in which the material for grinding is first of all crushed in a roller mill under high pressure so that agglomerates are formed, then undergoes treatment to break up the agglomerates and afterwards is classified on a screen classifier, the oversize fraction is returned to the roller mill and the proportion of the product passing through the screen classifier is passed to a closed-circuit grinding arrangement. Such a method is distinguished by a uniform grinding operation in both crushing stages, requires low energy consumption for conveying the material for grinding from the first crushing stage to the second crushing stage and thus permits a greater spatial distance between the two crushing stages.
