Three-Pass Sand Drum for Efficient Sand Reclamation

The S62 Series Triple-Pass Drying System is a high-efficiency, energy-saving sand drying equipment designed for modern foundry sand handling systems. It is widely used for moisture removal and temperature control of wet or high-temperature sands such as resin sand, coated sand, and regenerated sand.

Featuring a unique triple-pass drum structure and counter-flow hot gas design, it enables multi-stage heat recovery, significantly improving thermal efficiency and reducing energy consumption. The S62 series is an ideal solution for precise sand conditioning and continuous production in green foundries.

Triple concentric drums with "S"-shaped sand flow extend residence time and enhance heat transfer, achieving over 85% thermal efficiency.

Reduces fuel consumption by 30–40% compared to conventional single-drum dryers, lowering operating costs.

Equipped with multi-point temperature sensors and PLC control for precise moisture control (0.1–0.3%).

Compact design reduces footprint by up to 60% compared to conventional dryers.

Integrated dust removal system ensures emissions ≤20mg/m³; optional VOC treatment available.

PLC+HMI control with fault diagnosis, data logging, and remote monitoring for smart operation.
