Recycling plastic windows

Making new out of old
The recycling of plastic windows yields raw material for the production of new high-quality windows. Whole plastic windows including glass, mountings, sealing and reinforcements are chopped into small pieces in the shredder. Afterwards, the metal, glass and rubber are sorted out with the help of special separators. The remaining chunks of PVC are then reduced to a uniform particle size in a cutting mill. This material is sorted according to colour and then granulated. The end product of this recycling process is a sorted, high-quality PVC granulate. It is stored in large mixing silos. These are equipped with mixing tubes that ensure thorough mixing of the grey-white PVC granulate. The content of the silo is registered via level measurement. The measurement data provides the basis for regulating production and distribution.

Level measurement in blending silos with VEGAPULS 68
Typical application conditions are noise and dust during the filling process and abrasive products. That's why the VEGAPULS 68 radar sensor is the most suitable solution. The instrument is non-contacting and wear-free and was specifically developed for solids with unfavourable reflection characteristics. Its sensitivity is many times greater than that of conventional radar sensors. That ensures accurate measuring results even when the granulate has a low dielectric constant.

Level measurement with VEGASON 65
The VEGASON 65 ultrasonic sensor is a particularly cost-effective alternate solution. With its high-performance transducer, it is especially suitable for granulates with extremely low dielectric constant.
