Product Description
Introducing our state-of-the-art Customizable Fluidized Bed Sand Cooler, designed to revolutionize your sand cooling processes with unparalleled efficiency and precision. This continuous cooler seamlessly integrates cutting-edge technology to transform old, loose sand into a uniformly cooled state. Utilizing a powerful high-pressure fan, it creates a boiling sand bed that advances over strategically arranged coil cooling pipes. This setup ensures optimal heat exchange and film removal, delivering consistently cooled sand ready for reuse.
In the intricate realm of foundry sand regeneration, our cooler shines by swiftly cooling old sand and effectively stripping away film residues. This is pivotal for enhancing sand mold reusability and casting quality. Our equipment pioneers the continuous boiling cooling methodology and incorporates an advanced spiral tube heat exchange system, marking significant progress with old sand cooling to ≤40ºC and achieving a resin film removal rate exceeding 95%. We delve into how this equipment sets a new industry benchmark with its robust processing capacity of 20-50t/h and commendable energy efficiency of ≤1.8kW·h per ton - exploring its technical sophistication, unique advantages, diverse applications, and economic impact.
1. Technical principles and core design breakthroughs
Harnessing the inherent cooling characteristics of old sand (initial temperatures spanning 80-120ºC and film content between 3-8%), our equipment champions innovation through a dynamic, fluidized bed heat exchange coupled with a complex multi-stage wind-water synergy system:
Continuous fluidized cooling technology:
A robust high-pressure fan (operating at 6-10kPa) elevates the sand layer into a dynamic boiling state, achieving sand particle suspension heights of 50-150mm. The resultant heat exchange area is quintupled compared to a static bed, expeditiously reducing sand temperatures from 120ºC to a cool 45ºC in an astonishing 3-5 minutes;
Ingeniously arranged spiral cooling tubes, crafted from 316L stainless steel, meander in a serpentine pattern. These tubes facilitate reverse flow contact with cooling water (maintained between 5-25ºC), achieving an impressive 85% heat exchange efficiency—surpassing traditional shell-and-tube configurations by 30%.
Film efficient removal system:
Our centrifugal stripping module ensures sand particles, in their boiling state, scrub against tube walls, attaining a resin film breakage rate of over 90% and leaving a minuscule residual film thickness of ≤0.02mm;
Through a dual-stage system of cyclone dust removal and water film adsorption, we achieve exceptional purification (dust removal efficiency >99%), eliminating micro-powder particles (≤75μm) and film debris concurrently, with exhaust gas emission concentrations maintained below 10mg/m³.

2. Core advantages and industry value
By integrating continuous operation capacity with energy consumption optimization, our equipment supersedes traditional vibrating cooling beds, offering multi-faceted upgrades:
Efficiency and quality advantages:
Boasting a continuously adjustable processing capacity of 20-50t/h, our cooler delivers enhanced cooling uniformity (sand temperature standard deviation ≤2ºC), outperforming intermittent equipment by 50%;
The reduced loss on ignition (LOI) of regenerated sand, from 3.5% to under 1.2%, coupled with minimal tensile strength fluctuation of sand molds (≤0.2MPa), exemplifies our commitment to energy-saving and eco-friendly innovations.
Our closed design (ensuring leakage rates <3mg/m³) aligns with GB 16297-1996 standards, maintaining working environment dust concentrations below 1mg/m³.
Maintenance and adaptability:
Our modular spiral tube group, featuring a quick-release design, is engineered for rapid maintenance, allowing replacements in under 4 hours and curtailing average annual maintenance costs by a significant 60%;
Versatile enough to integrate seamlessly with vibrating screens and magnetic separators, forming a comprehensive 'cooling-purification-regeneration' production line, it is adept for use across resin sand, water glass sand, and other processes.
