Improved parametric resonance of a vibrating screen

Summary of the impact

A novel application of parametric resonance (PR) is described, which has improved the effectiveness of a vibrating screen used for size-sorting of crushed rock. These improvements have had an economic impact on the Ukrainian company that makes the screens: the mathematics developed in Aberystwyth permits a stable, high amplitude PR-regime to be found, reducing the damage to the screen mesh and increasing its longevity. This new technology is allowing the company to reduce costs and equipment downtime and is enabling them to gain a market advantage by being able to sort wetter materials than previously.
