The first optimization led to the results shown in table 1. It maximizes plant profit without activating any shape constraints. The secondary crusher was operated with a large CSS. The reduction ratio in the crusher was quite small while the capacity was large. There was no need to use a larger throw on the crusher since the capacity was ...
Crushing is a size reduction process that plays a key role in both mineral processing and crushing–screening plant design. Investigations on rock crushability have become an important issue in mining operations and the manufacture of industrial crusher equipment. The main objective of this research is to quantify the crushability of hard rocks based on their …
1.1 Imaging Techniques. The traditional methods to evaluate aggregate shape have received considerable criticism because most of these test methods are cumbersome and time-consuming; no one test can be used for coarse and fine aggregates at the same time; most of these methods are indirect ones in which the results of one property can be influenced by …
