Crushing characteristics ScienceDirect
Crushing characteristics. A method of measuring the basic characteristics of comminution was developed. These characteristics are expressed by the major comminution functions: crushing probability function, energy function and breakage function. The crushing probability function is the strength distribution of particles of a Crushing and screening is the first controlled size reduction stage in the process. This is the main process in aggregate production and a preparation process for further size reduction. Grinding is the stage of size reduction (wet or dry) where the liberation size for individual minerals can be reached.Basics in Minerals Processing_TON [PDF Document]

Pulverization 1: Definition and purpose The global standard
In a narrow sense “grinding” is used (also referred to as friction grinding in mining). “Grinding” refers to pulverization in the area of finer particle size (crushing of fine particles) and may be distinguished from crushing. Besides these, “milling”, etc. are also used. Thinky Corporation uses “pulverization”.
