Wood shredders & system solutions

UNTHA has stood for reliable wood shredding for decades. At LIGNA, the company presented its trusted single-shaft wood shredders – LR630, LR700 and LR1400 – along with complementary conveyor technology and metal separators. The 4th generation RS30 four-shaft shredder also made its debut to an expert audience.

These shredders can operate as stand-alone units or be integrated into full processing lines. When shredders, conveyor systems and metal separators are perfectly coordinated, residual wood is processed almost automatically, allowing operators to focus on their core business.

“With our system solutions, we offer customers fully tailored recycling plants for their residual wood, requiring minimal oversight. The wood is fed into the shredder, shredded evenly and any foreign materials are removed through metal separation. The resulting homogeneous raw material is then transported via conveyor to storage rooms or silos, and from there supplied to in-house heating systems for thermal recycling,” Josef explains.
