Dewatering Screen 911Metallurgist

Inclined Dewatering Screens The material is usually introduced as slurry. On an inclined dewatering screen the accelerations along with a portion of the gravitational force will cause the material to travel towards the discharge end while the water is being screened out by means of proper screening media. The resulting force for material travel is indied as the yellow arrow.

perforated and covered with a screen. The lower end of the pipe has a driving head with water holes for jetting (Fig 9.4.a,b). Wellpoints are connected to 5.07.5 cm diameter pipes known as riser pipes and are inserted into the ground by driving or jetting. The upper ends of the riser pipes lead to a header pipe which, in turn, connected to a pump.


The standard inclined screen has an angle of inclination of 15 o. Lower angles of inclination increase the projected area of the screen aperture in the horizontal plane and the screen can handle a greater load. This is accounted for by capacity factor K6 K 6 1.0 0.01(. 15) (411) where . is the angle of inclination in degrees. The wet screen
