Doppstadt Grinders are the true workhorses of the industry. These German engineered machines are designed to handle all categories of waste wood, from dimensional lumber to stumps to drywall, quickly and efficiently. The intelligent load sensing floor maintains consistent engine RPM, and the flail hammers swing freely to eliminate contamination. These remote-control machines have reversing fans with swing-out coolers for easy cleaning and maintenance. Screen changes take under 15 minutes, no tools required.
