 A rotary dryer is a widely used industrial equipment designed to reduce the moisture content of bulk materials through continuous, indirect or direct heat transfer. Characterized by a rotating cylindrical drum, it is essential in sectors such as mining, agriculture, chemical processing, and waste management, where drying is a critical step in material processing, storage, or transportation. Its ability to handle large volumes of diverse materials—from granular ores to sludges—makes it a cornerstone of many industrial drying operations.

The core rotating drum—steel-made with heat/corrosion-resistant linings—is inclined (2°–5°) to aid material flow. Support rollers and trunnion rings stabilize rotation, while a drive system (motor, reducer) controls speed (1–5 rpm). Internal lifters cascade materials to maximize contact with hot gas. Feed chutes, discharge hoods, heat sources (burners/exchangers), and exhaust systems (fans, filters) complete the setup.

Rotary Dryer Features

 Our single-drum rotary dryer delivers versatile drying solutions across industries,

● efficiently handling metal ores like iron ore pellets (moisture reduction for smelting), copper/zinc/lead concentrates (pre-shipment drying), and bauxite/alumina (processing prep).

● It excels with industrial minerals including silica sand (foundry preparation), gypsum (wallboard production), kaolin clay (ceramics), and limestone (cement).

● Specialty applications cover coal (thermal efficiency boosting), mineral sands (ilmenite/rutile/zircon), and salt/potash dehumidification.

● Additionally, it processes byproducts such as slag (construction materials) and mine tailings (volume reduction), ensuring optimal moisture control for diverse material streams.
