Hydroflux - Model RoSF3 -Grit Classifier

The grit-water mixture enters the vortex chamber either by pump or gravity, where a rotary motion is induced. An automatic air intake occurs through the centrally located drilling hole, enhancing the separation process.

At the core of the system is the Coanda Tulip, which ensures optimal grit classification. Incoming water adheres to the tulip wall and is redirected horizontally below the water surface, leveraging the Coanda Effect to minimise radial and tangential flows. This enhances separation by utilising density differences between organic and mineral materials.

The classifier screw then transports the cleaned grit up an inclined plane, where it undergoes gravity-driven dewatering before discharge into a skip. Under optimal conditions—such as with appropriate pre-screening and grit collection facilities—the system achieves a mineral residue purity of over 90%.
