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;
