Shortcomings of Vibrating Screen and Corrective Measures:

1. The vibrating screen has larger force of vibration and friction which causes the wear of the machine parts. The higher friction of the conventional vibrating screen leads to higher power requirement for instance in industries the motor power requirement is around 7.5 kW to 15 kW. 2.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
