High frequency vibrating screens are the most important screening machines primarily utilised . and nonferrous metals ores (e.g. lead, zinc, gold, silver and industrial sand etc.) . Furthermore, since the screen vibrates vertically, there is a 'popcorn effect' whereby the coarser particles are lifted higher and finer particles stay.
