Three Drum Rotary Dryer

Application
The three drum rotary dryer is a machine designed based on upgrades to the single drum rotary dryer. It dries materials in the form of lumps, granules, and powders as long as the material diameter is under 20mm. Compatible materials include slag, clay, coal, sand, etc. Three cylinder rotary dryers can be the ideal choice when looking for auxiliary equipment for mixed mortar and slag production lines widely used in building materials production, chemical processing, and foundry applications.

Applicable materials
The materials which can be dried by the three drum rotary dryer are mixed mortar, sand, slag of cement plants, clay, coal, mixture and iron powders.

Advantages
The final moisture of the materials is sure to be less than 0.5% after drying. The drum of three drum rotary dryer has an insulation design and the thermal efficiency can be up to 80%. Coal, oil and gas can be used as fuels of the three drum rotary dryer. The three drum rotary dryer is able to dry the materials in the form of lump, granule and powder as long as their diameters are under 20mm. Compared with single drum rotary dryers, the three drum rotary dryer economizes on floor space about 50%, investment in land about 50% and power consumption about 60%. The three drum rotary dryer can control the final moisture of the materials easily according to customers’ requirements The air outlet temperature of the three drum rotary dryer is less than 60% and the dust removal of which is durable. Additionally, it can produce packing continuously. The three drum rotary dryer is transmitted to tug and there is no need of gear and pinion set.
