Screening technology for granules, powders, and bulk materials

In process engineering, screening technology is the standard method for solid-solid separation as well as in dewatering technology. These process steps have a decisive influence on product quality, process reliability, and efficiency.

GKD supplies screen mesh and screen coverings for the precise separation of powders, granulates, and bulk materials. Optimized mesh construction with tight aperture tolerances and tailored materials ensure reproducible results and long service life.
