Abstract:
A method is described for adjusting the tightness of a wear part fastened to a fixed jaw and/or a moving jaw of a jaw crusher with a tightening device that has a screw fastened at its first end in connection with a wear part located on a first side of the jaw; and a tightening member fastened to a second end of the screw on a second side of the jaw; and a spring arranged between the jaw and the tightening member. The spring is compressed or decompressed with the tightening member; the spring is influenced by at least two moving screws supported by a frame of the tightening member. The length of the spring is changed by rotating the at least two moving screws.
