— And the crushing process in mineral and aggregate since come from this. What is the crushing process? Crushing is the process of reducing the size of materials so that they can be further processed. In …
— By improved efficiency a decrease in energy consumption per ton of crude milled should be achieved. Further savings resulting from finer crushing are realized in the concentration or mineral recovery phase of a process. These benefits are rather difficult to quantify due to the varying complexities of the concentrators and benefication processes.
— Viewing the crushing plant as an industrial process clearly shows that it is not the individual machines that need to be optimized.

— The higher Treton impact resistance for aggregate B-I results from its lower flatness (2:1) (45% of particles versus 86.7% of particles for aggregate B-QJ). This difference is a function of the crushing process (impact versus jaw crusher). This way, this regression model incorporates both mineralogical and crushing-related characteristics.
