S83 Series Double-Disc Mixing and Cooling Machine

　　This machine is mainly used for cooling old sand in sand handling systems. Each stream of sand stays in the machine for 2 minutes, allowing for sufficient cooling. Pre-mixing is completed during cooling, and the cooled old sand achieves three uniformities: uniform temperature, uniform moisture content, and uniform composition, creating favorable conditions for stable molding sand mixing performance.

　　During operation, moistened (approximately 4-5% moisture content) hot old sand is fed into the machine body through the inlet and is vigorously stirred by the scraper, moving in two circular patterns within the disc. Simultaneously, cold air is blown into the machine from the air inlets on the enclosure, exchanging heat with the sand. Hot air is discharged from the top exhaust pipe, and the sand is pushed out of the machine through the discharge port on the side wall by the outer scraper.
