Crushing roller

Abstract

Described is a roller for crushing of particulate material, such as crude ore for use in the mineral industry, where the roller body is provided with a roller shell having a plurality of individual wear segments. The roller shell is characterized in that adjacent wear segments have complementary sides and in that a number of the wear segments, prior to mounting of the remaining wear segments, are initially fixed to the roller body in order to provide guiding and fixation for the remaining wear segments which are wedged-in between the number of initially fixed wear segments.
