Secondary concrete crushers usually have some type of pulverizing jaws and are used on jobs where primary demolition is accomplished by hammers, crushers, blasting, ball and crane, or sawing. In this instance, the primary demolition work creates large quantities of concrete rubble which the secondary crusher further reduces, separating concrete from reinforcement.

Most crushers employ a combination of all these crushing methods. Impact Impact refers to the sharp, instantaneous collision of one moving object against another. During the collision, both the objects may be moving, such as a cricket bat hitting a fast moving ball, or only one object may be moving, such as a rock being struck by hammer blows.
