Innovative sieving machines for the efficient separation of glass fiber-reinforced polyamide spheres


Markus Hollbach, RHEWUM GmbH


The industry is continuously faced with the challenge of processing materials not only efficiently and economically, but also meeting the quality requirements of end products. A special focus is on the processing and separation of plastics, especially glass fiber-reinforced polyamide spheres (PA GF). These specialty plastics, enriched with glass fiber, offer improved mechanical properties and are therefore in high demand in many technical applications. Efficient sieving of these materials is crucial for the purity of the end product and thus for the quality. In this context, RHEWUM sieving machines play a central role.

Technological progress in sieving technology

RHEWUM's sieving technology is based on long experience and continuous development to meet the specific requirements of different materials. Particularly in the separation of glass fiber-reinforced polyamide spheres, it is essential to achieve precise separation to secure the desired material qualities. RHEWUM offers specialized sieving machines with innovative screening technologies that ensure a high degree of separation precision.

The challenge of sieving glass fiber-reinforced polyamide spheres

Due to its complex properties and its tendency to form agglomerates, glass fiber-reinforced polyamide presents a challenge in sieving. The precise separation of these materials requires a sieving machine that combines a high vibration frequency with an exact separation technique to achieve the perfect separation of the spheres without damaging the material. The avoidance of cross-contamination is also an important aspect, which is achieved through a sophisticated guidance of the sieve goods.
