Combining Acoustic Emission and Vibration Technologies Harbors Huge Potential for Material Characterization
The demand for raw materials is growing worldwide, in step with increasing world population and rising living standards of emerging countries. It is becoming more difficult to exploit primary raw materials because of declining ore grades and increasingly complicated mineralogies. Thus, the efficient and environmentally sustainable exploitation of primary resources using innovative technologies has emerged as an important research field to address these issues. An innovative approach is introduced to optimize process and quality control by combining acoustic emission (AE) and vibration technology. The general feasibility of these two technologies for material recognition and characterization is examined. The new approach was tested to determine whether coal could be distinguished from waste rock.
