Breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory. High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers.

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.
