Abstract (en)
[origin: WO2007147474A1] The invention relates to a method for reconditioning a used grinding roll of a high-pressure bed grinding mill. In said method, the surface of the rolling body is turned by a certain degree after removing the worn profiled members, whereupon the existing bores can be deepened to a depth that is sufficient for receiving new profiled members or new bores can be created according to a new bore pattern. New profiled members are then inserted into the bores. The inventive method allows a used grinding roll to be reconditioned in a particularly time-saving manner while economizing material.
