Setting the standard for quality – UNTHA Shredders are renowned for their reliability and robustness.

UNTHA four-shaft shredders   (Patent Nr. 319535) After being rapidly drawn in to the cutting system, the input materials are coarse and fine-shredded in a single operation. If parts do not immediately fall through the perforated screen, they are picked up by the teeth of the main cutter and transported up again (coarse-shredding). When this material is picked up by the secondary cutter, an additional cutting process (fine-shredding) takes place. The end product is a precisely definded, homogeneous granule.

UNTHA two-shaft shredders The cutting discs are arranged in such a way that a cutting disc on one shaft is positioned between two cutting discs on the opposite shaft. As a result, the material is shredded both lengthways and crossways. The size of the fraction produced is determined by the width of the cutting discs and the number of teeth.

UNTHA single-shaft shredders During the shredding process, the hydraulic swing-pusher in-feed system forces the material against the rotor carrying the exchangeable, reversible cutting blades, which shreds the material against the cutting bars. The shredded material then falls through the perforated screen. The diameter of the perforations defines the granule size.
