RTD Series – Heavy-Duty Rotary Dryers for Industrial Applications

The RTD Series rotary dryers are designed for continuous, high-capacity drying of bulk materials such as ores, slag, phosphates, clays, limestone, fly ash, and fertilizers. These robust systems operate by rotating a large, cylindrical shell at a low speed, allowing material to gradually pass through a hot gas stream for effective moisture removal.

Featuring customizable lengths, diameters, and internal configurations (such as lifting flights or lifter paddles), the RTD dryers can be tailored to handle a wide range of feed materials—from coarse granular solids to fine powders. Depending on the application, the dryers can operate in co-current or counter-current flow arrangements, optimizing thermal efficiency and product consistency.

RTD dryers are engineered for long service life, with wear-resistant liners, hardened support rollers, and sealed drive assemblies. Their ability to process abrasive, high-moisture, or temperature-sensitive materials makes them a preferred solution across the cement, mining, chemical, and energy sectors.

Key characteristics:

• High throughput and consistent drying performance

• Configurable gas flow (co-current or counter-current)

• Durable steel shell with customizable internals

• Designed for abrasive, heavy, or cohesive materials

• Compatible with direct or indirect heating systems
