Vibrating Screen Design Analysis

LC has extensive experience in the design, stress analysis and natural frequency analysis of vibrating screens used in mineral processing applications. Ludowici has become our biggest client in this field, and since 2003 we have analysed a number of their revolutionary LVS vibrating screens, supplementing their own in-house engineering.

Vibrating screens operate at high frequencies at up to 5g's acceleration reaching 10,000,000 cycles in approximately one week's duty. Thus the allowable design fatigue stress is very low in comparison to most other machines and structures. In order to ensure such minimal stresses, innovative design and careful manipulation of modal frequencies are required.

Vibrating screens can be tuned by way of altering the structure stiffness, and to a lesser degree the mass, in order to move any modal frequencies away from that of forced excitation. FEA provides the tool to do just that. Through iterations and subsequent changes to the design, a vibrating screen design can be produced with accurately predicted stresses and optimised modal frequencies.

With LC's experience in vibration analysis and strain gauging the FEA models predictions of stress and modal frequencies are easily verified and/or trouble shooted. LC has a depth of experience in trouble shooting vibrating screen design issues and providing reliable solutions in order to minimise unplanned shutdowns and reduce maintenance.
