A rotary dryer is a type of industrial dryer used to reduce or minimize the moisture content of materials. It works by tumbling material in a rotating drum while hot air is passed through.
A direct rotary dryer transfers heat through direct contact between the hot gases and the material, making it ideal for high-moisture bulk materials like ores and coal. An indirect rotary dryer, on the other hand, uses a heat exchanger or external heating to avoid contact between gas and material—suitable for fine, dusty, or temperature-sensitive materials.
Rotary drum dryers are suitable for a wide range of materials in mining and mineral processing, including:
Copper ore
Iron ore
Phosphate rock
Coal and lignite
Silica sand
Zinc and lead concentrates
We offer rotary dryers with drum diameters from 1 ft to 20 ft, extendable up to 24 ft upon request. Capacities range from 1 to 200+ tons per hour, depending on material properties, moisture content, and drying requirements.
Installation time depends on the dryer size and site conditions. For most mining applications, the average installation period ranges from 2 to 4 weeks, including commissioning and test runs. Our technical team offers full on-site support to ensure a smooth setup.
Yes. All rotary dryers can be fully customized, including drum dimensions, materials of construction (for corrosion or abrasion resistance), type of heat source (gas, coal, thermal oil), dust control systems, and PLC automation. We tailor each solution to your process.
Our dryers are engineered for maximum thermal efficiency, featuring optimized airflow paths and insulation. Compared to traditional drying methods, energy savings of up to 30% can be achieved, depending on the material and heat source used.
We provide full lifecycle support, including:
On-site installation and commissioning
Spare parts supply
Technical training
Remote troubleshooting and system upgrades
Maintenance packages for long-term reliability
30+ years of experience in drying technology
Exported to 20+ countries across Africa, Southeast Asia, and South America
