Protective liner for crusher

A method for assembling a protective liner in a crusher having a protective liner, the protective liner comprising a plurality of lining segments arranged circumferentially along a wall of the crusher, wherein at least some of the segments have a trapezoidal shape with two bases of different lengths arranged parallel to the circumferential direction of the wall and two non-parallel legs connecting the bases, wherein at least some of the segments are arranged along the circumference of the wall such that long and short bases of adjacent segments alternate, and wherein at least some of the segments are allowed to vary in their axial position with respect to the adjacent segments to compensate for tolerances in a diameter of the wall of the crusher, the method comprising:

• a first step of attaching at least two segments to the wall of the crusher, such that an interval along the circumferential direction of the wall is defined between two segments of the crusher, wherein the wall is not covered by any segment in the interval;
• and
• a second step of inserting a further segment into the interval and adjusting the position of the further segment in an axial direction of the wall so that the wall of the crusher is covered with segments arranged along the circumferential direction of the wall, such that the non-parallel legs of the adjacent segments at least partially contact each other.
