In this apparatus for crushing brittle material for grinding a size reduction device is arranged between a roller mill ( for pressure crushing) and a screen classifier (for classifying the crushed product) for disagglomeration of the crushed product in round and flat form (agglomerates). For energy-saving and reliable disagglomeration of these agglomerates the size reduction device has an inlet section with feed arrangements for agglomerates and fluid as well as turbulence section, so that the agglomerates can be intensively intermixed and at least partially broken up in the first section and completely disagglomerated in the second section, whereupon a feed pump feeds the dissagglomerated crushed product to the screen classifier as a fluid suspension without clogging.

In apparatus for crushing brittle material for subsequent grinding having a roller mill in which said material is crushed using high pressure and approximately round and flat agglomerates are formed, a classifier for classification of the product of crushing in the roller mill, and a size reduction device arranged between the roller mill and the classifier having a fluid feed and in which the agglomerates from the roller mill are intermixed with fluid and disagglomerated, the improvement wherein said size reduction device is divided into an inlet section including feed arrangements for the agglomerates and the fluid and a turbulence section having at its lower end a feed pump to receive the intermixture of fluid and disagglomerated crushed product, said agglomerate feed arrangement of said inlet section comprising a chute opening into a feed channel to which said fluid feed arrangement is connected to provide a driven water injector which connects said inlet section to the inlet of said turbulence section.
