The utility model relates to the construction, in particular to jaw crushers.The jaw crusher comprises a frame (1), onto which there are fixed at an angle fixed (2) and slide (3) plates with curvilinear lower part, and a drive installed in the upper part of the slide plate (3). Novelty consists in that the slide plate (3) is articulated in the lower part; the curvilinear part is made in the form of a cylindrical surface with the center of curvature coinciding with the axis of articulation. Under the fixed plate (2) it is installed with the possibility of rotation about the longitudinal axis, a cylindrical roller (6) interacting through the crushable material with the curvilinear part of the slide plate (3). The drive of the slide plate (3) may be made in the form of hydrocylinder (5). The plates may be equipped with changeable wedge teeth (12). The displacement of the lower edge of the slide plate (3) with respect to the lower edge of the fixed plate (2) may constitute 50à350 mm.
