The STF-Group is one of the leading manufacturers for plastic recycling and washing machinery especially for PET-, PE-, PP-, PS-post-consumer-plastics with more than 60 turnkey plants and several single devices delivered worldwide. Furthermore we are recycling more than 130.000 t/a of PET bottles to high quality flakes and 30.000 t/a RPET-granules for the packaging and beverage industry in our own plants in Germany. With this amount STF is the biggest PET-recycler in Europe. Thus all our machines are “Made In Germany”, have been tested in our own production and are optimized for low energy, water and chemical consumptions to get the best quality, durability and a fast return on investment for our customers.
The Label Scraper is suitable for removing labels and sleeves of all kinds as well as external dirt from bottles by mechanical friction between cutting elements on a rotating drum and fixed elements in exchangeable housing components. The stator elements can be preadjusted for different bottle sizes and can be adjusted if necessary.
The Bottle-Screen has a solid octagonal shaped body with an integrated screen in the bottom. It is made for rinsing of post-consumer packaging and remove outside dirt like sand, mud and other adherences.
Installed in front of STF's Grinder it expands the life of the knives and allows higher throughputs. In combination with STF's Label Scraper it can be integrated in the sorting section for better detection in the optical sorters and improvement of yield.
Wet Cutting Mill
The cutting mill type KSM 800 series has been developed especially for the wet comminution of postconsumer plastics. High and continuous capacity is secured by the 5 / 7-bladed V-cut rotor and feeding device, which has been designed and optimised for the comminution of bulky plastics and is powered by 90 –160 kW. Within the cutting mill, the intense water supply allows an effective comminution, with high cleaning effect.
