Product Description
Introducing the premier cooling solution: our Fluidized Bed Sand Cooler, expertly designed to simplify your foundry operations. This continuous cooler starts by introducing loose old sand into the cooling bed. Under the powerful influence of a high-pressure fan, the sand reaches a boiling state, gracefully navigating through a maze-like coil cooling pipe. As it journeys forward, the potent combination of robust suction and cooling water ensures the old sand is thoroughly cooled and meticulously stripped of its film.
In the intricate realm of foundry sand regeneration, the swift cooling of old sand and the meticulous removal of film residues are paramount for maximizing the efficiency of sand mold reuse and the superior quality of castings. This advanced series employs state-of-the-art continuous boiling cooling technology, paired with an innovative spiral tube heat exchange system. Such a sophisticated setup guarantees a groundbreaking enhancement in cooling down old sand to a remarkable ≤40ºC and achieving a resin film removal rate exceeding 95%. In this insightful article, we delve into how this cutting-edge equipment revolutionizes the sand cooling process, boasting a continuous handling capacity of 20-50t/h while ensuring an impressively low energy consumption of ≤1.8kW·h per ton of sand. We explore its technical principles, core advantages, transformative industry applications, and the substantial economic benefits it offers.
1. Technical principles and core design breakthroughs
This equipment ingeniously revolutionizes the cooling characteristics of old sand (initial temperatures ranging from a scorching 80-120ºC and film content of 3-8%) through dynamic advancements in fluidized bed technology and a sophisticated multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
The high-pressure fan, delivering an impressive wind pressure of 6-10kPa, propels the sand layer into a dynamic boiling state. The particles ascend to a suspension height between 50-150mm, creating a heat exchange area that is exponentially larger—5 times, in fact—compared to a static bed. Astonishingly, the sand temperature plummets from a searing 120ºC to a cool 45ºC within a mere 3-5 minutes.
Innovatively designed spiral cooling tubes, crafted from resilient 316L stainless steel, are skillfully arranged in an intricate serpentine pattern. As the cooling water, chilled to a refreshing 5-25ºC, flows counter to the sand, an exceptional heat exchange efficiency of 85% is achieved—marking a substantial 30% improvement over traditional shell-and-tube structures.
Film efficient removal system:
The centrifugal stripping module facilitates an extraordinary process where sand particles, in a boiling state, vigorously interact with the tube wall. This dynamic friction results in a resin film breakage rate surpassing 90%, with any residual film thickness carefully controlled to be ≤0.02mm.
The sophisticated two-stage purification system, combining cyclone dust removal with water film adsorption, ensures a dust removal efficiency exceeding 99%. This process adeptly eliminates micro powder (≤75μm) and film removal debris, maintaining an exhaust gas emission concentration below a minimal <10mg/m³.

2. Core advantages and industry value
Elevate your operations to new heights with our state-of-the-art equipment, which surpasses traditional vibrating cooling beds by delivering unparalleled upgrades in continuous operation capability and energy consumption efficiency:
Efficiency and quality advantages:
Our equipment boasts an adaptable processing capacity, continuously adjustable between 20-50t/h. It achieves an incredible cooling uniformity with a sand temperature standard deviation of ≤2°C—a staggering 50% improvement over conventional intermittent equipment.
Experience a remarkable reduction in the loss on ignition (LOI) of regenerated sand, plummeting from 3.5% to below 1.2%. Enjoy consistent tensile strength in sand molds, with fluctuations kept to a mere ≤0.2MPa. Our equipment also champions energy-saving and environmentally friendly attributes:
Boasting a tightly sealed structure with a leakage rate of <3mg/m³, it adheres to the stringent GB 16297-1996 standard, ensuring a dust concentration in the working environment of less than <1mg/m³.
Maintenance and adaptability:
Our modular spiral tube group, designed for quick-release, can be replaced effortlessly in less than 4 hours, slashing the average annual maintenance cost by an impressive 60%.
Innovatively, it can integrate vibrating screens and magnetic separators to form a comprehensive "cooling-purification-regeneration" production line, perfectly suited for resin sand, water glass sand, and other processes.
