TECHNICAL NOTES

the default parameters can be used for planning. The primary parameters needed to design a fish screen are: 1. Approach velocity (flow velocity toward the screen and based swimming speed of the target fish). 2. Screen sweeping velocity (flow velocity along the screen and based on the fish's ability to maintain swimming speed before resting). 3.

AGGRETEK Dewatering Screens

The two vibrators initiate a linear motion, driving particles in an uphill, downhill or horizontal direction – so water is strained down through the sand bed and below the screen deck. Drive Vibration on AGGRETEK's dewatering screens is produced by vibrators which can be run at different speeds depending on the application.

Dewatering Screen

The basic movement of dewatering screen is linear with horizontal mounting or upward inclination. With a high angle of attack and high acceleration, extremely low residual moisture values can be achieved. Based on the low conveying speed a high product layer will be created at the screen deck end, this gives an additional dewatering effect.
