RAP, however, is not hard rock, and the unique characteristics of RAP crushing can actually cause cone crushers to negatively impact product output. As cone crushers crush and re-crush the RAP to break it apart, the asphalt can be literally stripped from the RAP, creating white rock, which now requires the extra step and cost of recoating.

Handbook of Crushing TerraSource Global

2019-6-3  Impact In crushing terminology, impact refers to the sharp, instantaneous collision of one moving object against another. Both objects may be moving, such as a baseball bat connection with a fast ball, or one object may be motionless, such as a rock being struck by hammer blows. There are two variations of impact: gravity impact and dynamic impact.
