Lindner Washtech GmbH products

The high-performance, robust shredders of the Micromat series guarantee optimum pre-shredding and bale opening of waste plastics. These shredders reduce the feed material to the exact grain size needed for the downstream processes, from 8 to 250 mm.

The Rafter is an efficient pre-washing unit for heavily contaminated, primary shredded plastics, such as post-consumer LDPE films and hard plastics made of HDPE and PP. In three different phases contaminants and impurities such as metal and glass and loose material adhesions are effectively separated – optimally preparing the input material for the downstream washing process.

The friction washers from the Twister series ensure highly efficient cleaning of contaminated plastics. Even the finest particles of dirt are removed in a highly dynamic washing process and then separated through a screen. Friction is generated by directing jets of water onto the rotor.

The hot-wash system is specially designed for extremely tough contaminants and removes even grease and oil adhering to the material, while also eliminating any glue residues and unpleasant odours. Through the combined use of three special components – reactor, hot-wash Rafter and hot-wash Twister – the system delivers a highly-effective and at the same time continuous cleaning process.

In the Loop Dryer the plastic granulate is dried mechanically and any particles adhering to the material are detached using controlled centrifugal force. The dryer spins the plastic granulate at approx. 600–1,000 rpm, drying it in the process. The water and any particles such as paper adhering to the material are reliably separated through a special screen.
