is a powerful high-efficient star screen. 2 separate screening decks divide the material in 3 different fractions. The regular rotation of the star elements loosens, recirculates and transports the material. By means of different star shaft speeds the material can be torn apart. Then, the coarse, medium and fine fraction are discharged by 3 separate conveyors. All the DOPPSTADT machines stand out for their easy operation and high mobility.
