The aim of the invention is to provide grinding rolls in particular for
high-pressure roller mills or rolling presses for pressure grinding a
granular material not only with a wear-resistant coating but also with a
face armour plating in the area of the roller annular edge, which has a
long service life due to the high wear resistance thereof and whose
production and repair are, in general, relatively simple and inexpensive.
For this purpose, the inventive face armour plating consists of a
plurality of prefabricated hard bodies which are circularly arranged side
by side in such a way that the circular face edge of the roller is
formed, said hard bodies are disposed on said circular shoulder of a roll
shell such that said hard bodies are placed axially and radially against
said circular shoulder of the roll shell and are movably assembled with
the roll shell.
