Chromite sand prevents the sintering problem in sand that is in contact with metal.
In this way, it makes the casting surfaces higher quality.
Chromite is used as a shell and applied to the metal surface, and the rest of the mold is filled with silica sand.
Chromite found in molding sand is more valuable than silica sand and this sand must be separated.
With the TES-SAN chromite recovery system, it is possible to separate 95–99% of the chromite in the molding sand.
TES-SAN produces all the equipment in the system from the first entry of the sand to its shipment to the silo.
The TES-SAN Chromite Reclamation System is designed to effectively separate chromite and silica sand used in foundry molds, achieving a 95–99% recovery rate. Chromite sand, used as a facing layer in contact with molten metal, helps prevent sintering issues and ensures smoother, higher-quality casting surfaces.
Up to 95–99% chromite recovery efficiency
Superior casting surface finish
Eliminates sintering problems in contact zones
Reuse of valuable chromite sand
Reduced molding costs
Fully integrated system designed and manufactured by TES-SAN – from sand input to silo transfer
Chromite is applied as a shell layer near the metal contact surface, while the rest of the mold is filled with more economical silica sand. TES-SAN’s system separates the two sands, allowing chromite to be reused efficiently without material loss.
