Germany: Doppstadt has patented a new method to clean star screen machines during operation. The new method helps the screening stars clean themselves by introducing finger gears into the space of neighbouring star screen shafts. This strikes the neighbouring star screen shaft and shakes off adherent materials. The new system will be used with Doppstadt screens SM 518 and SM 620 in both mobile and stationary applications. It can be operated either with a trommel or with a screening deck.
