Abstract
A moving point involved in a movable teeth plate of an eccentric jaw crusher rotates on a closed loop, being called hysteresis curve in the specification. An angle between a major axis of the curve and the surface of a fixed teeth plate is a significant factor for crushing. The inventor found the fact that the alternation of the angle enables crushing ability to be rich. The angle is incontinuously varied. One of the positions at which a toggle plate is rotatably supported is selected. A larger angle is suitable for crushing harder materials, concrete for example, a small angle being suitable for soft materials, asphalt, for example. One self moving crusher can crush harder and soft materials at the same field where buildings are destroyed, or roads are repaired.
