Similar to all the Doppstadt SM trommels, the SM 720 works on the rotating drum principal where the size of material removed is dictated by the size of aperture holes in the drum screen.  The patented, load-sensing material feed enables an optimum utilization of the large screening surface of 38.8 m².  Thanks to the modular principle, the basic machine can easily be equipped with a wide choice of options to meet your specific requirements.
