Sand Separation System
The patent pending sand separation system can be engineered for new furnaces or integrated into existing thermal sand removal furnaces. Such furnaces heat castings encased in sand with a stream of high velocity hot air. The hot air causes the organic binder to decompose, releasing sand into the furnace chamber. Portions of this sand are mixed in the air stream, damaging fan blades and internal furnace component. This system, which is installed in the recirculated air stream, was developed to fulfill a need for a modernized system that can separate sand from the hot air stream. Development testing has shown reduction in fan blade wear, increasing the life of fans and internal components.
