The electronic elliptical-motion screening machine enables the speed and the throw angle to be adjusted while the machine is running: adjustment can be done manually on a touch panel or fully automatically, via a profibus integrated into the plant control system – without having to stop the machine at all!

This means that the benefits of both vibration types are combined in a horizontal screen. Horizontal screens have a stroke range of 14–20 mm and typically run at a stroke of 16–18 mm and a spinning speed of 750 rpm. Between 0.2 and 0.25 meters per second, materials move through the screening medium.
