### P&Q University Lesson 8- Screening

Oct 11, 2019· Dewatering on a vibrating screen produces a dense, compact filter cake that moves to the screen deck. Polyurethane and profile wire are the best media options for dewatering screening. Typically, the screen deck is minus-3 degrees (negative slope). The filter cake traps smaller particles and allows water to pass through to the screen deck openings.
