[PDF] Nonlinear Model of Vibrating Screen to Determine …
Springs of vibrating screens are prone to fatigue induced failure because they operate in a heavy duty environment, with abrasive dust and under heavy cyclic loads. If a spring breaks, the stiffness at supporting positions changes, and therefore the amplitude of motion and the static and dynamic angular inclination of deck motion also change. This change …

LinaClass® SLG Linear Motion Vibrating Screens
The vibrating screens perform a linear movement at an angle of impact to the hori-zontal, generating the move-ment of the material. Overcriti-cal systems are applied. This enables the vibrating screen to be operated stably and makes it extremely insensitive to un-steady loads. By means of con-tinuous accelerations, the water is caused to flow off.
