Cabka Recycling uses Lindner Micromat HP

At its Weira site, mixed plastics from a range of different fractions are processed on all its lines. These fractions generally include PE, PP, PS and PET as well as additional materials such as caps and labels.

The plastic recycling lines run seven days a week in continuous shifts. After shredding, drying and mechanically cleaning, the new raw materials are transformed into the different end products at the very same site. “The choice of the right shredder plays a crucial role in the recycling process,” says Christian Leicht, Technical Manager at the Weira site. “To achieve a high level of productivity, it is especially important to maintain a consistently high throughput together with minimal downtime. The Micromat HP has impressed us in many respects.”

“We specifically designed the single-shaft shredder Micromat HP for the heightened demands in plastic recycling. For instance, this sector requires a greater throughput and the plastics being processed have a significantly higher level of contamination,” adds Jan Rosenmeyer, Sales Manager at Lindner Recyclingtech. “This is why we’ve equipped the new Micromat HP with a powerful direct belt drive and an adjustable torque. The wear parts are designed such that they can be easily replaced – the rotor is easy to access to ensure contaminants can be removed quickly without any problem.”

Leicht describes their initial reaction: “When Lindner offered us the new Micromat HP for a trial run, we were initially sceptical. However, comparative tests with the existing shredders in our plant surprised us – in a good way. We can achieve an output many times higher than before with the Micromat HP and we are also impressed by the ease of maintenance. The screw-on wear parts such as the knives and knife holders are easy to replace without time-consuming welding or other compromises,” says Leicht. Both plastic lines are serviced entirely in-house. The shredder’s knives are maintained – rotated or replaced – every seven days due to the three-shift operation. If the knife holder is damaged due to a contaminant, it can also be easily replaced. “Just recently we’ve added a second Micromat HP, which delivers a throughput equal to that of the two shredders we had previously,” Leicht adds.
