Screw Classifier

Ideal sand dewatering

The solution from the specialists: Intelligent. Efficient. Precise.

The easy-to-service and cheap-to-run screw classifier from Binder+Co for raw materials for construction and industrial minerals proves to be an optimum solution when it comes to dewatering sand from hydro cyclones or lower screen residues. And when it comes to precise and reliable classification of solids in suspension.

The Binder+Co spiral classifier at work

The spiral classifier separates the respective feed slurry into a dewatered coarse material and a fine slurry. It consists primarily of an inclined tub and a transport screw for the coarse material. The fine material residue is at the lower end of the tub; the coarse material residue is at the upper end. The separation of the solid grains is based on the principle of different sedimentation rates of the grains in water. The coarse material is suitably dewatered before discharge through upward conveyance above the level of the slurry.
