4.1 Classification Based on Sieving - Vibrating screens The basic method of operation of a screen is very simple. The screen presents a barrier to the passage of oversize material while it readily passes undersize material. It is only necessary to ensure that each particle has an opportunity to reach the screen.
the trays surface. During a vibrating stroke the tray surface travels between its lowest point A to its highest limit C. On the upward stroke, the particle is in contact with the tray from A to B. At that point the velocity of the particle become greater than the
Jul 26, 2015 Screening is best done using 0.7 to 1.1 ton of water for every 1 ton of rock. The objective is not spraying water on the screen, it is to dilute the feed to the screen. An alternative to trying to spray on water is to install a simple measured water bladefall at the front of the screen deck.
