A crusher includes a replaceable first crushing member having a first crusher surface and a replaceable second crushing member having a second crusher surface. The co-operation of the crusher surfaces is defined by at least one crusher setting parameter. From measurements of a quality parameter, which relates to the nature of the crushed material, on at least two different occasions during the service life of a set of replaceable first and second crushing members and on each occasion for at least two different settings of the crusher setting parameter, a control function can be determined that describes a value, of the at least one crusher setting parameter, which on a given occasion gives a crushed material the quality parameter of which is substantially optimal. The control function is utilized for the adjustment of the crusher setting parameter for a subsequent set of replaceable first and second crushing members in such a way that on a given occasion for the subsequent set of replaceable crushing members, a crushed material is also obtained, the quality parameter of which is substantially optimal.
