A highspeed impactor (such as a hammer or a ball) instantaneously impacts a solid object, or objects collide with each other at high speed to cause crushing. This process is used for pulverization into medium and smallsized objects (10 cm or less). ＜Shear pulverization＞ An object is cut into small pieces by a wedge, such as a cutter.
