SCREENING ON A SCREEN WITH A VIBRATING SIEVE

The screens with vibrating sieves are characterized by high frequency of vibrations and small amplitudes. In the screen tested by the authors, the frequency is 50 Hz and a maximum amplitude is 2 mm. The angle of sieve inclination can be changed in the range from 0 to 35°, i.e. twice as large inclination is obtained as compared to the screens with stable sieves. So large angles and high ...
