ABSTRACT:
A vibratory structure of a screening apparatus has two shafts connected to rotate together by a toothed belt. Each shaft carries an eccentric weight which may be adjusted relative to the position of the shaft. The amplitude and frequency of the screening apparatus may be easily adjusted by adjustment of the weights and change of the transmission ratio between the two shafts.
