Abstract
The vibrating screen have a screen deck, two sidewalls and a mechanical vibrator comprising two shafts, rotating at the same rotation and in opposite directions, each one of the end portions of each shaft carrying an eccentric weight and being supported on bearings which are supported in the sidewalls of the vibrating screen. The shafts have their end portions, adjacent to each other, supported on bearings mounted to a same bearing case fixed to beams, transversal and having opposite ends fixed to the sidewalls of the vibrating screen. Each end portion of a shaft carries an eccentric weight with a total mass different from that one of the eccentric weights of the end portions of the other shaft, said shafts rotating in determined phases, defining the inclination of the major axis of an elliptical movement imparted to the screen deck.
