Sand recycling roasting furnace for resin sand production line

Advantages of the Calcination Furnace Production Line:

**Stable Casting Quality and Fewer Defects:** High-temperature calcination thoroughly removes moisture, 

organic matter, and volatiles from the sand mold, reducing defects such as porosity, flame ignition, and slag

 inclusions during casting. Castings exhibit high density and a smooth surface.

**High Dimensional Accuracy and Minimal Deformation:** The sand mold, after high-temperature curing, boasts 

high strength and rigidity, minimizing mold bulging and deformation during casting. Castings exhibit excellent 

dimensional consistency, making it suitable for precision and complex castings.

**Wide Applicability:** Suitable for various materials including cast steel, cast iron, stainless steel, and alloy steel.

 Particularly suitable for thick and large castings, high-grade castings, and heat-resistant/wear-resistant castings.

**High Recycling Rate of Used Sand and Low Overall Cost:** Calcination restores the sand's properties well, 

allowing for multiple recycling cycles, significantly reducing new sand consumption and lowering molding sand 

costs.

**Cleaner and More Environmentally Controllable Production Environment:** Centralized collection and treatment 

of flue gas and dust eliminates wet sand dust, resulting in a clean workshop. Complete combustion of organic 

matter further reduces odor and harmful gas emissions.
