Trommel Screen vs. Vibrating Screen – Which Do I Need?
Vibrating screens employ a rectangular or circular motion to convey materials along the screening surface. These screens consist of a vibrating mechanism that induces vibrations, promoting the movement of particles for effective separation. Vibrating screens rely on their vibratory motion to convey materials along the screening surface.
Vibrating Screens
The basic concept behind vibrating screen design is the transmission of vibrations to a screening surface in order to effect a separation. The chassis of a screen is its primary component, and it provides support for the various surfaces that make up the screen.
