Crushing it
The primary crushing stage generally breaks down the material into pieces of max 200 – 300 mm. The aim is to achieve the right balance between feed size (capacity) and throughput (speed). Reaching this balance is important, as focusing on one aspect, while neglecting the other, could lead to an unsuitable choice of equipment.

Modelling of granular materials at crushing-dominant stage
Granular crushing significantly changes mechanical behaviours, especially under elevated stress levels. Therefore, this study aims to develop a model to simulate the constitutive behaviours of granular materials at the crushing-dominant stage. Firstly, the contour of elastic potential energy is demonstrated and employed to derive the yield surface or function, …

Selecting the right crusher for your operations
Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

Selecting the right crusher for your operations
Cone crushers, which are also known for their ability to crush hard, abrasive ores and rocks, break material by squeezing or compressing it between convex and concave-shaped surfaces.
CHAPTER 7: DEFORMATION OF ROCKS STRUCTURAL …
As we have seen in Chapter 6 on metamorphic rocks, stress will deform crustal materials, which is something that can happen at any temperature or pressure. Deformation can be either brittle or ductile, depending on temperature and pressure, how fast stress is applied, and the mechanical properties of the rocks (Fig. 7.1).
