ABSTRACT:
A swing type crusher capable of efficiently breaking a non-rigid object into pieces of small particle size. A jaw crusher breaks a lump of asphalt cast into a V-shaped crushing space (V) which is defined between a fixed tooth plate (26) and a movable tooth plate (25), and which periodically changes its volumetric capacity. A toggle plate (12) is interposed between a body (1) and the movable tooth plate (25) to swingably support the movable tooth plate (25). A support member (9) which swingably supports the body-side end portion of the toggle plate (12) is vertically movably secured to the body (1). By vertically moving the support member (9), the spacing between the fixed tooth plate (26) and the movable tooth plate (25) is narrowed (widened), and at the same time, the stroke of the movable tooth plate (25) is reduced, thereby efficiently breaking a non-rigid object, e.g. waste asphalt, into small pieces, and reusing them immediately.
