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.
