What are Eccentric Shafts in Vibrating Screens?
But eccentric shafts in vibrating screens use fewer moving parts, so they're easier to maintain than those irregularly interlocking shaft couplings. Furthermore, elliptical drive systems are easier to control, more resilient when extreme loads are on the move, and they're clearly a more versatile mechanism.
