Turnkey industrial drying solutions with rotary dryer
1.Product Introduction
The core equipment of this solution is the Rotary Dryer, also known as a rotary cylindrical dryer or drum dryer. Its structure consists of a slightly inclined horizontal rotating cylinder equipped with internal lifting flights to agitate the material. This ensures thorough contact between the material and hot air or flue gas for high-efficiency dehydration. Widely utilized in coal, biomass, minerals, chemicals, and animal feed industries, this equipment can process materials with initial moisture content as high as 70%–75%, delivering a dried product with uniform and stable moisture levels.
2.Application
The rotary dryer is designed to process an extensive range of materials, primarily categorized into the following sectors:
1. Minerals Metallurgy
- Ores: Iron ore sand, metallic concentrate powder, flotation concentrates.
- Electronics: Hard magnetic ferrite powders.
- Coal Industry: Coal, coal gangue, coal slurry, and tailings.
- Building Materials: Cement raw materials, clay, gypsum, slag, and limestone.
2. Chemicals Fertilizers
- Agriculture: Compound fertilizers, phosphate fertilizers (raw materials
and finished granules).
- Industrial Waste: Chemical residues, municipal sludge, and industrial
waste for environmental treatment.
- Specialty Chemicals: Active Pharmaceutical Ingredients (APIs), pesticide
formulations, and high-purity chemical products (suitable for
Vacuum Rotary Dryers).
3. Food Bio-products
- General Food: Fish meal, feed additives, yeast, and fruit juice concentrates.
- Heat-Sensitive Materials: Probiotic powders, spices, tea, and coffee
where flavor or bio-activity must be preserved (suitable for
Rotary Vacuum Dryers).
4. Agriculture, Biomass Bulk Solids
- Biomass: Straw, forage, and other biomass raw materials.
- Bulk Materials: Yellow sand, dry-mixed mortar, and various aggregates.
3.Working Principle
The rotary dryer is a continuous drying system. Its core operational principle relies on an inclined rotating drum that integrates multiple heat transfer mechanisms, including conduction, convection, and radiation. As the wet material is agitated, it maintains thorough contact with the heat source for high-efficiency dehydration. The drum is typically installed at an inclination angle of 0.5° to 5° and rotates slowly. Wet material is fed from the elevated end and is continuously lifted and showered by internal flights under the combined forces of gravity and rotation, creating a uniform "material curtain."
As the material advances toward the lower end, high-temperature hot air or the heated drum wall transfers heat to the material, driving moisture evaporation. The resulting vapor is extracted by an induced draft fan, and the final dried product is discharged from the outlet.
