THE TECHNOLOGY OF CRUSHING
The ability to crush material is governed by the laws of physics involving mass, velocity, kinetic energy,
and gravity. However, it is impractical to reduce the process of selecting and sizing a crusher to a series of
formulas. The selection process is largely based on experience and testing: experience with actual field
applications and laboratory tests that show how a given material will be reduced by a given crusher type.
The main purpose of this handbook is to explain the principles that govern the technology of crushing
and also to impart the practical knowledge gained by Pennsylvania Crusher over the past century
