A vibration screen includes a duct with classifying sieve installed without tension, a vibration exciter, supporting shock absorbers and a dynamically active surface located under upper sieve and made in the form of elastic strings stretched in parallel across the duct. Furthermore, between classifying sieve and elastic strip an additional polymeric sieve is installed without tension, which cells are for 5-10 times bigger than the cell of upper classifying sieve. |
