Screening Machines Comparison

The eccentric vibrating screen relies on the high-speed rotation of the eccentric drive shaft to make the screen vibrate, so it is called the eccentric vibrating screen. The eccentric shaft directly drives the screen frame to make a trajectory movement in the vertical plane with an amplitude equivalent to twice the eccentricity.
