This high-end GKM tumbler screening machine has been specially designed and adapted to meet the requirements of the food and pharmaceutical industries. In order to fit the limited space, GKM Siebtechnik manufactured this double capacity machine. The idea is to split the product into several decks to ensure very high throughput in a small footprint. A drainable design ensures an ideal internal and external high level cleaning process. The machine has an external as well as internal high-grade stainless steel design. The high-quality surface finish is polished and extrapolated to prevent product build-up to meet highest customer requirements. The contamination-free ULTRA-VARIO-SONIC screen cleaning system provides a much more efficient screening action for the ultra-fine cut points. With the GKM tumbler screener in combination with an ultrasonic cleaning even the finest cut point down to 20 microns can be realized. As a result of the cleaning method, the throughput is significantly increased on the same surface area. The patented fully pneumatic Twin System for deck lifting and clamping combined with quick-release

In the recycling process of PET bottles, a GKM vibration screening machine is used to clean the washing water of the PET flakes. A GKM tumbler screening machine is used for fractionating and dedusting the finished PET flakes. Raw materials from recycling The recycling of materials is becoming increasingly important due to the scarcity of raw materials and for the sake of environmental protection. This also includes recycling of PET. In recycling, waste products reintroduced a new production cycle, respectively, base materials become secondary raw materials. The materials produced in this way are referred to as recyclate or regenerate materials (source: Wikipedia). From 2025 on, non-refillable PET beverage bottles in the EU member states (regulation (EU) 2019/904) must contain at least 25% recycled plastic, so-called recyclate. Recycling of PET bottles In the recycling process of used for PET bottles, depending on the procedure, the labels and caps are sometimes removed in advance after that the bottles are sorted by color and then shredded. The next step is usually the washing of the crushed mass, afterwards dried and freed from final impurities. For this recycling process of PET bottles,
