moving ball, or only one object may be moving, such as a rock being struck by hammer blows. There are two types of impact: gravity impact and dynamic impact. Coal dropped onto a hard surface such as a steel plate is an example of gravity impact. Gravity impact is most often used to separate two materials which are having relatively different friability. For example, in a rotary breaker ...
