READ MOREScreens are available in a single motor design for elliptical motion or a dual motor design for linear screening and can work with either a horizontal or incline set-up. Each vibration method ensures the particles passing along the screen, if small enough, will have the opportunity to fall through the screen mesh between the start and end of the deck.
