Rotary-drum-dryer

Product Description:

Drum drying is a method used to dry out liquids of wet materials. The rotary drum dryer is used to reduce or minimize the liquid moisture content in the biomass material(wood, wood chips, sawdust, straw, stalk, etc.). it is handling by bringing it into direct contact with hot gas. The totary drum dryer is widely used to dry various materials in the mineral industry such as sands, ores, fertilizers, wood chips, coal, limestone, stones and soil, iron sulphate, filter cakes, sewage sludge, etc.

Features of Rotary Drum Dryer:

1. Large intensity of drying, high dispersion of the material, all the surface area of particles can be effective drying area.
2. Short drying time.
3. Simple structure, small footprint, easy to build and repair.
4. Large capacity, high thermal efficiency. When drying combined no water, the thermal efficiency can reach 60%.
