Thermal Processing Solutions
for Sand & Aggregates
Welcome to the future of sand processing, where innovation meets necessity. Sand is essential in shaping modern life, from towering skyscrapers – where it adds bulk, strength, and stability to materials like asphalt, concrete, and cement – to the smartphones we use daily, which rely on silica sand. The sand processing journey is complex. Sand extracted from the ground requires thorough cleaning, screening, processing, and drying to meet the high standards of the industrial and construction sectors. This is where advanced thermal processing technology becomes essential.

FAQs
What makes rotary dryers well-suited for sand and aggregate processing?
Rotary dryers are designed for high-volume, continuous operation and can handle the abrasive, dense nature of sand and aggregate materials. Custom internal flighting optimizes contact between material and the heated shell, delivering uniform moisture reduction across high throughput rates.
How does Heyl Patterson address equipment wear in abrasive sand applications?
Our systems are built with heavy-duty shells, abrasion-resistant internal components, and robust drive assemblies engineered to withstand the constant wear of sand and aggregate processing. We also offer custom material selections for flights and liners based on your material’s specific abrasion profile.
Can your systems meet frac sand moisture specifications?
Yes. Our rotary dryer systems are engineered to achieve precise moisture targets required for frac sand and proppant applications, including compliance with API standards. Controlled retention time and heat zone management support consistent, repeatable results.
How do you control dust and fine particle loss during sand drying?
Heyl Patterson systems incorporate advanced sealing technology, optimized airflow configurations, and integration with dust collection systems to minimize fine-particle entrainment and carryover during the drying process.
What throughput ranges can your sand processing systems accommodate?
We design rotary dryers and coolers for a wide range of production scales, from smaller specialty operations to very high-capacity frac sand and aggregate facilities operating 24 hours a day. Systems are custom-engineered to meet your specific production requirements.
