Sand Coolers

Cool hot sand in foundries and aggregate processing operations to desired temperatures.

Efficient sand cooling with low energy consumption

Consistent outlet temperatures for downstream processing

Heavy-duty design for reliable, continuous operation

Carrier Vibrating Fluid Bed Sand Coolers

Carrier’s sand coolers are designed to cool hot return sand to temperature and moisture levels that are ideal for mulling. The drilled fluidizing decks evenly distribute air into the sand bed, preventing hole pluggage and maximizing thermal efficiency. The special hood design minimizes dusting for uniform exhaust velocities. The result is consistent return sand temperature and moisture content.

These coolers are ideal for foundry and processing applications and utilize a three-stage system to cool sand evenly. While our sand cooler systems can be designed to meet your needs and application, the processes involve three basic steps:

Water addition

Mixing

Cooling in Fluid Bed

Features & Benefits

Evaporative sand cooling process provides maximum thermal efficiency.

Fluidization with vibration mixes and turns the sand bed to eliminate hot spots resulting in uniform temperature.

Because the sand moisture is evaporated while cooling, the cool sand is consistent in temperature and moisture.

Air volume controls regulate and maintain supply and exhaust air volumes at a constant pre-set level to prevent fines entrainment and sand weepage.

Continuous plenum discharge incorporates a double seal to discharge weepage sand if loss of supply air should occur.

Special sand dryer hood design minimizes dusting and produces more uniform exhaust velocities.

Consistent return sand temperature and moisture content.

Since no moving parts are in contact with the sand, minimal sand dryer system maintenance is required.

Equipment Options & Accessories

Three-stage Sand Cooling Systems

Specifically designed for foundries, this system utilizes controlled water addition, aggressive mixing, and fluid bed cooling to lower hot return sand to ideal mulling temperatures.

Fluidized Deck Designs

Over 100 deck designs ensures the proper fluidizing deck for precise airflow and consistently distributed heat.

Water-Addition Systems

Water addition systems raise the moisture level of sand as needed in order to enable evaporative cooling to function.

Predictive Controls & Automation

Optional PLC-based controls with high-speed temperature transmitters monitor multiple points in the processing zone, automatically reacting to product conditions to prevent wet or overheated sand discharge.

Materials of Construction

Equipment can be fabricated from carbon steel, stainless steel, or other specialized alloys, and outfitted with abrasion-resistant liners or material coatings to reduce product adhesion.

Access Manways & Doors

Access the plenum and deck with a variety of customized manway and door configurations.

Safety Features

All dryer system components can be designed with fire and explosion prevention, detection, and suppression systems.

Applications

Foundry Green Sand

Specifically designed for handling green sand to reduce temperature, remove dust, and manage moisture. Cools return green sand using controlled airflow, vibration, and water addition to achieve consistent discharge temperature and moisture. Uniform conditioning prepares sand for reliable molding and reuse.

Frac Sand

Process frac sand by taking extremely hot sand straight from drying or calcining kilns and cooling it down to safe, manageable storage or packaging temperatures. Prevent the sand from scorching or degrading while ensuring uniform temperature control.

Industrial & Aggregate Sand

Used for cooling sand and aggregated materials after thermal processing, including dried powders and hot granular materials. Featuring controlled airflow and vibratory material movement with uniform bed conditions promote consistent heat transfer and stable discharge temperatures for downstream processing.

Silica Sand

Provides uniform cooling of silica sand through controlled airflow and vibration. Consistent bed depth maximizes heat transfer while achieving predictable discharge temperatures for classification, storage, or downstream processing.

Sand Coolers FAQs

Why are dedicated sand coolers needed in foundry operations?

Hot sand from processes like foundries or aggregates requires controlled cooling to achieve consistent moisture and temperature before reuse or downstream handling.

How do fluid bed sand coolers improve efficiency?

They evenly distribute air across the material, ensuring consistent cooling while preventing pluggage and maximizing heat transfer efficiency.

Can sand coolers handle high throughput and variable feed conditions?

Yes. Carrier systems are designed to manage surges, varying moisture levels, and inconsistent feed rates without disrupting performance.

What are the benefits compared to traditional cooling methods?

Fluid bed sand coolers provide more uniform cooling, better moisture control, and lower energy consumption than many conventional cooling approaches.

Can these be integrated into existing sand processing lines?

Yes. Carrier engineers design sand coolers to integrate with existing dryers, conveyors, and reclamation systems.
