Since the vibrating screen operation is very complex and involves several variables in a multiphase process, the one-way coupled approach was able to analyze In this article, one of the critical technical objects of the Ore Enrichment Plant—the vibrating screen used for the sieving process—is considered. The main purpose of sieving is to separate the fine fraction (suitable for milling) from the coarse fraction (requiring crushing). The horizontal schema of the vibrating screen is shown in Figure 1.Minerals Free Full-Text Application of Wavelet Filtering to
