Conveyor troughs for fluidization

Conveyor troughs and discharge aids based on metal meshes and mesh laminates from GKD

In the chemical industry, petrochemicals, and process engineering, conveyor troughs ensure the continuous transport of powders and granulates. With a porous metal mesh laminate bottom, the bulk material is fluidized by air introduced from below and can be moved evenly in the conveying direction – similar to the behavior of a liquid.

GKD supplies tailored metallic mesh solutions, metal mesh laminates, and built-in components to ensure maximum process reliability.

Challenges in practice

Fine or cohesive powders tend to agglomerate quickly, leading to bridging or dead zones in silos and conveyor troughs.
Operators require robust, cleanable discharge systems that function reliably even at high temperatures and in aggressive media.

Solutions from GKD

GKD develops metallic mesh bottoms for conveyor troughs. Stainless steel meshes and multilayer laminates distribute compressed air evenly and ensure continuous material flow. The meshes can be customized to particle size, bulk density, and temperature requirements. They are available as plates, segments, or complex 3D-formed parts and can be easily integrated into new or existing systems.
