Triple drum sand dryer

The machine can be applied in drying raw materials such as yellow sand, slag, clay, quartz sand etc..It's widely used in industries such as dry mortar, cement, building materials, glass, chemicals, and casting etc. The dryer is assembled by three concentric-cylinders which halved joint with different diameters. Computer optimized stock guide and lifting blade with different angles and spacing are installed inside the cylinder, the structure can ensure that the material being dried runs along the direction of screw under the impact of gravitation, stay sufficient time and good dispersion in the cylinder to let the material exchange with the heat airflow from air heating furnace inside of the cylinder. The special three cylinder structure makes the inner cylinder and middle cylinder being surrounded by the outer cylinder to form a self-contained thermal insulation system, the radiated heat from surface of inner and middle cylinder assist heat the material in the outer cylinder, but the outer cylinder is at the low temperature end, so the heat dissipation area and heat loss is reduced significantly. 
Advantage:
1. Triple drum dryer can take full advantage of excess heat, reduce heat loss and increase the heat exchange area, making the unit evaporation intensity of the dryer greatly improved, thereby effectively improving the heat energy utilization rate, reducing the energy consumption and making the heat efficiency of triple drum dryer improved in a wider range. Compared with single-cylinder dryer with the same efficiency, its heat efficiency is improved about *0% and energy consumption saving doubles.
2. Because the cylinder length of the triple drum dryer is one third of single-cylinder dryer and the base area saves about *0% than the single-cylinder dryer, the base investment is reduced correspondingly.
3. The dryer drives by adopting the friction between supporting roller and rolling ring, and the transmission power is low, thereby reducing the noises when the equipment working.
4. The cylinder sealing system of the dryer adopts micro-contact technology, with better sealing effect and reducing the dust pollution.
5.The cylinder and raising material board of the dryer both adopt alloy steel plates which is double service life of common steel plates.
6. Triple drum dryer can use coal, oil, gas or biomass as fuel,can dry different shapes of material, such as lump, granular, powder and various materials.
