Two proven grinding principles intertwined into one seamless procedure – the DZ 750 makes a strong case for the solution-minded Doppstadt expertise.Festivities kick off with the tried and tested low-speed shredding process known from the DW series. Exclusively designed as a recycling system for scrap wood, the DZ 750 separates the incoming wood and extracts the bulk of ferruginous particles on the spot with the help of overband magnets. Passing through a scraper floor, the scrap wood then reaches the high-speed grinding unit as used in the AK series. There, the powerful flail mullet drum cuts the material to the desired size.  Free-swinging shredding tools provide maximum flexibility and can be exchanged within minutes thanks to the proven „Dopplock“ interlocking system.The icing on the cake is another downstream magnetic separation unit which takes care of the remaining Fe-particles that somehow made it through to here.Turning scrap wood into a high-quality, ready-to-use end product in a single, seamless shredding process – the DZ 750 by Doppstadt makes this as easy as taking candy from a baby! 
 
The Doppstadt grinders stand out for their free-swinging flail holders with separately replaceble wearing tools and the heavy duty rotor running at approx. 1,000 rpm.Easy maintenance thanks to large protection doors on all sides, separate drives for scraper floor and feed-in roller optimizing the material feed and the throughput. Wide range of possible applications as all the shredding tools of the mobile doppstadt series can be used.
