The rotary dryer, as a material heating and drying device, realizes drying process by making materials inside the coaxial rotary drum move back and forth between the inner and external wall driven by the spiral vane and interrupted spiral raising plate.

Rotary dryers or kiln dryers are mainly used to dry slag, clay and coal powder in the construction and metallurgy industries, and leaching residue of the metal processing industry. Rotary dryer is widely used for drying materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control drier temperature. The temperature change of drier's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350oC)

There are many kinds of dryer machines in mining industry. The commonly used equipment is roller dryer. This machine has many advantages. The rotary dryer is mainly composed by the revolving body, lifting plate, driving device, supporting device, sealing ring and other components. So it has the advantages of reasonable structure, perfect workmanship, high yield, low energy consumption and convenient operation.

Rotary dryer uses reasonable operating parameters, and its coal and electricity consumption is 10-15 % lower than ordinary dryer. Hongji rotary drying machine is suitable for drying coal, slag, sludge, clay, fly ash and other powdery, massive or granular materials. Hongji Mine Machinery is a professional rotary dryer manufacturer in China, our rotary dryer has reasonable price, good quality, high productivity and low energy consumption.

The Main Components of Rotary Dryer

Rotary drum dryer mainly consists of rotary body, lifting blade, rotating device, supporting devices, sealing ring and other components. Rotary body is supported by the front and back supporting wheels, feeding and discharging devices, gearings, gear cover and other devices. Hongji rotary drying equipment is associated with ancillary equipment such as combustion chamber, feeding and discharging equipment and dust collection device.
