the heat efficiency can be up to 80%, save fuel. Shorter length, save cover space, fewer maintenance.
Three cylinder 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:
2. Because the cylinder length of the three-cylinder dryer is one third of single-cylinder dryer and the base area saves about 60% than the single-cylinder dryer, the base investment is reduced correspondingly.
3. The dryer drives by adopting the friction between supporting roller and belting leather, 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. Three-cylinder dryer can use coal, oil, gas as fuel,can dry different shapes of material, such as lump, granular, powder and various materials.
