MELT FILTRATION | MACHINERY
Clean break: melt filtration
Developments in melt filtration include a number of filters with increased throughput – with one collaborative effort claiming to handle 6 tonnes/hour of post-consumer plastic
One of the themes of K2025 was ‘Green – Smart – Responsible’ – and this was encapsulated by the many new melt filtration technologies on show. Melt filtration has become far more prevalent in plastics in recent years because of the rise of plastics recycling – for the creation of both post- industrial and post-consumer recyclate. Many developments were focused on higher throughput. Break Machinery says its new Duo 7000 – launched at K2025 – is the world’s largest constant- pressure screen changer. With a 7,000 cm² filtration area, it claims to offer
more than twice the capacity of any other single unit constant-pressure laser filter. This, it says, allows it to meet higher production demands. The larger filtration surface ensures fine filtration without raising working pressure, which reduces equipment dress while improving overall energy efficiency. Replacing multiple smaller machines significant- ly cuts maintenance and downtime required for screen changes. By consolidating operations into one Duo 7000

reduces the number of screens needed – which lowers operator hours, cuts production costs and simplifies workflow, it says. �

The new LF 812 high-performance laser filter from Erema has twice the screen area of its previous equivalent model. “This takes a step towards meeting the growing demands for high throughputs in plastics recycling while achieving the highest quality of melt,” said Markus Huber-Lindinger, managing director of Erema. The larger screen surface of the filter boosts
throughput or maintains throughput while using screens with finer filters. The larger surface area also makes it possible to operate at lower pressure and with less thermal load. Up to 5,000 kg of melt can be filtered per hour with the single version of the new laser filter. Combined with the new Intarema 2021 TVEplus, which has a throughput of up to 3.5 tonnes per
