Abstract

This grinding roller intended for use in a material bed roller mill comprises a basic body and a roller shell composed of individual firmly clamped segments, and several sheets of softer material which run transversely and are aligned radially are cast into each segment which is made largely from chill casting. In a simple manner this produces a surface profiling of the roller shell which remains approximately constant during the operating life of the segments with improved feeding behavior of the material for grinding.
