Among the wet materials drying equipment, the three drum dryer has improved on single-tube rotary dryer as high efficiency and energy saving product. Three drum dryer is mainly used for drying certain moisture and particle size of the materials, applied in a number of enterprises and industries, it has achieved good results. Three drum dryer improves the internal structure of original single-tube rotary dryer, and prolongs the time of pre-drying of wet materials and wet materials in the machine, coupled with the seal, moisturizing and reasonable supporting measures, so that its production capacity has improved 50-80% compared with the original single-tube rotary dryer, and unit volume evaporation strength is up to 120-180kg/m3, standard coal consumption is not more than 6kg/t. It has advanced technology, reasonable operating parameters, simple and feasible operation. Widely used for drying various industries of slag, clay, fly ash, iron powder, mineral powder and other admixtures, especially used for drying all kinds of sand in cement building materials, dry-mixed mortar, glass, chemical, foundry and other industries.
2. To ensure final moisture of materials is 0.5% or less, and it is the preferred product for dry-mixed mortar and slag powder production line.
3. Self thermal insulation efficiency of cylinder is up to 70% (traditional single-tube rotary dryer thermal efficiency is only 35%), to improve the thermal efficiency of 35%.
4. The fuel can be coal,oil, natural gas, etc. Massively dry granule and powder materials of less than 20mm size.
5. Comparing with single cylinder rotary dryer, three drum dryer occupys 50% land areas, reduces construction investment by 50% and reduces powder consumption by 60%.
6. Finished product moisture can be adjusted based on requirements of clients.
7. Outlet temperature is lower and the working life of dust collector is longer.
8. Use riding wheel to transmit instead of big and small gears.
Processed Materials: River sand, artificial sand, silica sand, yellow sand, mineral sand, mineral powder, slag, coal ash, coal slag, etc.
Application: Dry-mixed mortar industry, cement, building materials, glass, foundry industry, chemical industry, etc.
