Vibrating screen is mainly characterized by a high frequency, high vibration strength, and is mainly applied to the wet classification of 0.5mm or less fine material and solid-liquid separation. In the coal dressing industry, it was used to recover slurry in the most coal dressing plant for its low investment and operation costs. It has been widely promoted and applied at home and abroad.

The Vibrating screen had been researched in the abroad in the early 1950s. In the metallurgical industry, it was used for classifying fine iron ore in the Ore beneficiation plant. In the coal processing industry, it was used for slim dehydration, referrals and classification. At present there are many countries with this technology, such as the United States, Australia, German, France and Finland. The product also has many types, such as SLV type high frequency vibrating screen produced by Schenck Company and HF type vibrating screen by Nordberg Company.

The theory model of structure dynamics is the base of vibrating screen dynamic design. For the simple structure of vibrating screen, the theory model can give satisfactory results. For the complex structure such as multi screen, circular vibrating screen , the primary results may have a big deviation, but it can be an important reference for the arrangement of measure point in the follow-up model test. We can also change and revise finite element model of vibrating screen combined experimental modal parameters. So structure finite element analysis is an important step of vibrating screen dynamic design.
