We can provide a rotary drum dryer for many industrial drying application. We have been manufacturing and installing dryers for many years, and have the knowledge and experience required to provide a cost effective drying solution that not only works but works well.

Sludge rotary drum dryer is widely used to dry materials in industries like coal, sludge, mine, construction, chemical, ceramsite, etc. Thermocouples are installed in feeding and discharging units to control temperature. Temperature change of the dryer also can be indicated by the thermometer, which is convenient for temperature control inside the dryer ( it’s usually 250-350 ℃).

Powder & particle: Limestone, ore, clay, mineral filter cake, coal, iron sulphate, fly ash, gypsum etc.
Damp and sticky material: Coal slime, sewage sludge, bentonite, kaolin etc.
Corrosive material: Slag etc.
