SAND CASTING EQUIPMENT.

In the modern foundry industry, the technical combination of planetary rotor sand mixer and double disc cooler is reshaping the sand processing process standards. This solution achieves industrial-grade efficiency of 40 tons of green sand per hour through the high coordination of six modular equipment.

Technical innovation of sand mixing system
The planetary rotor sand mixer adopts a three-stage speed regulating device (120-1800rpm passing), two-way countercurrent sand mixing technology, and a composite motion trajectory to ensure that the water content deviation of the molding sand is ≤0.3%. The double rotor powerful sand mixing improves the uniformity by 50% and shortens the sand mixing cycle. The patented wear-resistant alloy blades extend the equipment life to 2.8 times that of traditional products

Breakthrough in energy-saving cooling system
The double disc cooler is equipped with a heat exchange recovery device, which can reduce energy consumption by 30%. The measured data shows that the inlet sand temperature of 280℃ is stabilized at 45±5℃ after three-stage cooling. The modular heat exchange design has a cooling rate of 15℃/min, and the environmental protection standard of dust concentration ≤10mg/m³ is achieved at the same time. Rapid cooling + moisture adjustment, precise control of sand temperature ±3℃, avoiding porosity defects in castings;
