TECHNICAL NOTES 4 VIBRATING SCREENS - Mineral Tech

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. In practice each particle is given several opportunities to pass through the ...

THE ROLE OF SCREEN SELECTION ON MEDIUM RECOVERY

The drain stage consists of a sieve bend and a vibrating screen. Sieve Bend The sieve bend (patented in 1957 by F.J. Fontein of the Dutch State Mines) consists of a curved screen with slots which run across the width of the screen. The direction of flow is at right angles to the screen as shown in Figure 2.
