 · >>>>>The feed to a vibrating screen consists of a mass of material in different sizes. The oversize will retard passage of the undersize, and this temporary restriction results in a build up of material on the screen surface. The bed diminishes as the undersize passes the opening. However, the bed of material should never reach a depth where the undersize does not stratify before it discharges ...
