Improvements in vibratory screens of mechanical type, characterized in that the masses that cause the vibration are set movably mounted on radial grooves made in two fixed plates at both ends of the screen axis having a spring in each plate to maintain said mass in its position closer to the axis when it does not rotate, moving the mass little by little as the speed of rotation increases, but the vibration does not start until reaching the speed of speed, for which the spring is appropriately dimensioned.
