Read more...screening is done by free fall, meaning that no particle layer can build up on the screen deck. The particles are sized directly via the screening media, giving a higher capacity (more compact installation), but low efficiency. A screen using parallel bars or rails is commonly called grizzly.

Read more...Screening is carried to out by a manually cleaned bar screen (large in size, in order to reduce the frequency of screenings collection operations) or, preferably, by an automatically cleaned bar screen (essential in cases of high flow rates of for water with a high solids content). The automatic bar screen is usually protected by a sturdy ...
