In processing of particulate solids, there are circumstances under which interparticle and particlewall impacts cause damage to the particles. In some cases, such as comminution, this is desirable, while in other cases it is undesirable, as for example in attrition of weak and friable particles in pneumatic conveying. These processes share the same underlying mechanisms, namely, the formation and propagation of various types of crack. It is therefore of great interest to identify and quantify the conditions under which particulate solids are damaged.
