PET hot-wash system and Micromat premium shredder

Lindner – hall A6 booth 6108

Besides digitalisation and automation, the circular economy is a key topic in the plastics processing industry. Changing from a linear to a circular economy, the quality of the recycled material plays an increasingly important role. Lindner, manufacturer of shredders, system solutions and industrial washing systems for plastics recycling, is taking on this challenge and will be presenting a new hot-wash system for recovering PET. Equipped with the new hot-wash tower and the also new Lindner step dryer, the company is setting new standards in PET recycling.

When shredding the plastic to be recovered, the focus of Lindner’s Micromat series is firmly on quality, reliability, robustness and experience.

The Micromat, Lindner Recyclingtech’s original powerhouse, shreds waste materials reliably and efficiently. The signature feature of the Micromat series is its Mono Fix rotor, which guarantees universal applicability by enabling different or mixed rotor configurations. Various pointed or flat knives and special counter knives can be fitted to one and the same rotor as required depending on the input material. As a result, this Mono Fix technology ensures a high and consistent throughput with a wide range of materials that are often classified as difficult.

The latest product from Lindner’s subsidiary Washtech is the hot-wash system with the PET hot-wash tower and Lindner’s step dryer, which were developed specifically for the PET sector. The innovative stainless steel step dryer dries the material particularly gently by slowly adjusting the rotation speed in five steps. This results in less friction and a lower fines content. The compact step dryer delivers throughputs of 1,000-3,000 kg/h at a drive power of 30 kW.  Thanks to the new hot-wash, the last remaining contaminants such as adhesives, labels and prints are completely removed from PET bottles. The PET hot-wash tower can be operated with or without caustic solution and works with a separate water circuit. Gentle cleaning and defined dwell times guarantee high-quality output materials, which are the perfect basis for producing food grade rPET.

Lindner Washtech supplies the turnkey line including NIR sorting, label remover and water treatment. “With our new washing components, we also want to set new standards in the PET sector and make an important contribution to a functioning circular economy,” emphasises Harald Hoffmann, Managing Director at Lindner Washtech.
