Abstract

Disclosed is an apparatus and a method for the comminution of brittle material in a roll crusher.
The method comprises the steps of introducing fresh material feed into a roll crusher which is divided into two distinct feed inlet zones which are at least one initial feed inlet zone for said fresh feed material and at least one secondary feed inlet zone for feed which has been stressed at least once by said roll crusher. Each initial feed inlet zone and each secondary feed inlet zone directs feed into, respectively, a corresponding initial feed crushing zone and secondary feed crushing zone. In the invention, fresh feed material is introduced into the roll crusher only in the initial feed inlet zone(s) whereby it is stressed at pressures sufficient high to cause the formation of at least some agglomerates.
The product thus formed is recirculated, without causing any substantial disintegration of the agglomerates, into the roll crusher through the secondary feed inlet zone whereby it is further stressed at pressures sufficient to cause the formation of at least some agglomerates.
