Ultrasonic screening systems
The sound waves excite the screen frame or the waveguide to produce high-frequency vibrations. These vibrations are evenly transmitted into the screen mesh across the full surface of your frame. The vibrations reduce the frictional resistance between the particles and the screen mesh.
Principles of Screening and Sizing
Figure is multiplied by the sq. footage of the screen deck. • Calculation gives the basic capacity of each deck and the total capacity of the vibrating screen. • The vibrating screen capacity is determined: • Using a standard sizing formula (9 variables). • Basic capacity of each deck opening. • Unique factors of that application. •
