Advanced waste reduction and shredding technology is the key to solving a growing number of environemental issues, including hazardous waste disposal, diminishing landfill capacity, and effective resource recycling and reclamation.

UNTHA has been an international leader in mechanical size reduction technology for over a quarter of century. Our advanced shredding technology and wide range of mechanical shredding systems enable us to provide cost-efficient, flecible, custom shredding solutions for virtually any commercial and industrial shredding application.

One of Europe’s largest shredder manufacturers, UNTHA produces the world’s best shredders for reducing waste by-products and recyclable materials. UNTHA patented the four shaft shredder over thirty years ago. They also manufacture industry leading single shaft machines along with specialized machines for converting waste to alternative fuel.

	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.
