From introduction: "The purpose of this bulletin is to discuss the theory of crushing and grinding in relation to present-day discoveries and developments and to consider the various mechanical appliances from a theoretical basis."

In crushing, particles are reduced in size to such a level that grinding can be conducted, while grinding allows to achieve the desired liberation size. Besides, the process of comminution can be simple or complicated depending on the nature of the ore and the suitable degree of liberation.
