Frac Sand Dryers

When you’re drying frac sand for oil and gas production, downtime isn’t an option. Malco designs and fabricates high-capacity frac sand dryers that meet demanding production schedules and extreme environmental conditions. Whether you’re operating in the Permian Basin or beyond, we build the systems that keep your process moving, with the responsiveness your project needs.

Choose from rotary or fluid bed drying systems, customized to your site specs and engineered for maximum uptime. From feed to finish, Malco delivers complete dryer systems with high-heat performance, corrosion resistance, and full fabrication in our U.S.-based facility.

Dryers That Drive Production

Frac sand must be dried before it’s transported or used in hydraulic fracturing. With moisture content affecting everything from transport cost to well performance, having the right drying system matters.

Malco builds industrial sand dryers and frac sand drying equipment designed for:

• High-volume processing
• Consistent drying across variable sand sizes
• Reduced fuel consumption and efficient heat transfer
• Long-term reliability in remote and harsh conditions

Choose Your Dryer Type

Rotary Dryers

Rotary dryers are the most common and rugged choice for frac sand drying. Malco’s rotary systems are engineered to handle large volumes of sand with uniform drying, high thermal efficiency, and minimal maintenance.

Best for:

• High tonnage operations
• Coarser frac sand
• Remote job sites

Fluid Bed Dryers

Fluid bed dryers offer excellent control over temperature and airflow, ideal for fine or uniform particle sizes.

Advantages:

• Faster heat exchange
• Energy efficient for smaller throughput
• Consistent product moisture content

Our team will help determine the right drying system based on your operation’s specific flow rates, feed variability, and performance goals.

What’s Included in a Malco Drying System?

Each system is custom-engineered and fabricated in-house for full integration and performance.

Typical system includes:

• Feed and conveying equipment
• Burner and combustion chamber
• Rotary or fluid bed drying chamber
