Statistical analysis of fragment shape of rock grain after ...

The overall shape of fragments generated after grain crushing was focused on, while the local undulation and roughness changes of fragment surface caused by fracture were ignored. Although the grains shapes are different, there are some generic features of shape distribution of fragments after crushing.

Portable Rock Crushers - Metallurgist Mineral

2020-12-16  Crushing is accomplished by the high velocity impact (5000 fpm) between the hammers (and liners) and individual pieces of rock in the feed, with the only means of support of rock fragments being the inertia of the rock itself. Under these conditions the rock fragments should not only be less massive than the hammer, but also quite friable.

At higher normal stresses, crushing of the rock fragments begins to take place, with the result that the friction angle diminishes. The shape of the strength envelope is related to the degree of fracturing and the strength of the intact rock (see Section 4.2). Weak intact rock: Rock such as the tuff shown in Figure 144 is composed of fine-grained
