The SM 720 SA Plus adapts to the screening tasks by component changes.
The new Doppstadt SM 720 SA Plus can separate nearly any solid input material in up to six different fractions by means of this screen. Raw materials can include construction rubble, industrial waste, biomass or garbage, plastic, glass, paper or wood, sand, gravel, scrap or slag. Compared to the previous model, the new screen is larger and more powerful. The 7,2 m³ hopper can be filled continuously and the screen can receive and discharge more bulk material in shorter time. The rear and side discharge conveyors are longer, so that the conical pile becomes higher and larger by a quarter and has to be removed less frequently. The driving power of the trommel has nearly doubled (plus 40 per cent) enabling a higher throughput. The SM 720 SA Plus also adapts to changing screening requirements. It can be equipped with various screening trommels with different mesh sizes. Different recyclables can be processed in one machine and the trommels can be changed without tools in less than fifteen minutes. The start and stop and the screening trommel speed are controlled comfortably at the machine rear. A semi-trailer can be used to transport it on the roads without a special permit. The machine complies with the exhaust limit values of Euro IV (Tier 4 final). Source: http://doppstadt.de/en/news/
