The following example demonstrates a method of selecting the components of an aggregate plant. Good component efficiency and part performance pre-evaluation is essential to a solid design. The aggregate production requires the consideration of several crushers, feeders and screens. This is not intended to be a typical situation, though it …

This is due to the fact that particle breakage rises with confining pressure and leads to the production of additional fines. This impedes relative particle mobility and reduces the lubricating effect. As a result, the rate of breaking with saturation decreases. Similarly, Wu et al.
