Extrusion International 6-2025

64 Extrusion International 6/2025 RECYCLING The Fourth-Generation Micromat Presented Energy ef ciency meets ultimate material diversity: At the core of the new Micromat series is a new gen- eration, energy-ef cient drive con - cept, which operates at an ef cien - cy of 97%. Also new: The adjustable rotor concept which enables a quick change between pointed and step knives, ensuring ultimate material exibility. Simple adjustment of the cutting gap, a new coupling con- cept, effective counter knife cool- ing, intuitive menu navigation and patented automatic belt tensioning complete the new shredder series. At K 2025, Lindner unveiled the next generation of Micromat: The ever-popular plastics shredder has undergone a targeted upgrade and sets new benchmarks in ef - ciency, exibility and ease of servic - ing. Lindner has built on the tried- and-tested strengths of Series III – a successful and established concept that the market has enjoyed for many years. The recycling pioneer’s Micromat IV is a trailblazing solu- tion with new features that are optimally designed for the needs of the modern plastics industry – aligned with the motto ‘Ready for the future of your business!’ Energy ef ciency rede ned The fourth-generation of this stationary single-shaft shredder presents an impressive, energy- efficient and maintenance-free drive concept. At its core is a state- of-the art synchronous reluctance motor that achieves IE6 energy efficiency class, and offers remark- able efficiency > 97 %. In com- parison with a torque motor, the reluctance motor does not use any rare earth metals and, with consid- erably lower energy losses in wind- ing and bearing, it is particularly durable and robust. With the new coupling function, the drive system is also completely maintenance-free: The drive belts are automatically tensioned so they are always at the optimum point. If a foreign body is detected in the ma- chine, the pressure is released from the hydraulic cylinder to protect the drive unit. Another advantage: Changing the belt is a quick and easy operation that the customer can per- formon site without needing any ex- ternal service personnel. Our propri- etary belt running-in system ensures that the belt is optimally tensioned after replacement. A smart system that saves time and money. Material exibility and ease of servicing The new multicut rotor is another highlight and combines maximum exibility in handling diverse material Lindner’s Micromat series is established globally as a reliable solution for shredding plastics. The fourth-generation Micromat has built on the proven strengths of Series III, with added upgrades that improve both maintenance and productivity.
