Lr520 COMPACT AND RELIABLE The LR520 wood shredder is a single-shaft shredder specifically designed for joineries and wood working companies with a waste wood volume of less than 3 m³ per week. Thanks to its pusher-free design, this low-maintenance wood shredder has a very small footprint. The low drive power as well as the integrated shut-down function when idling significantly decrease energy costs. The powerful drive concept in combination with UNTHA‘ s tried-andtested cutting system provide for a reliable shredding process. The wood chips are either discharged via an integrated discharge screw or an external extraction device. Powerful technology combined with well-known UNTHA quality features turn the LR520 not only into the most reliable wood shredder of its kind but also the most cost-effective one.
