The machine can be applied in drying of 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 together
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 losses are reduced significantly.
Main Technical Parameters:
Theoretical production output(t/h)
Coal consumption(Each ton of dry sand/standard coal)(Kg)
1. Three-cylinder 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 three-cylinder dryer improved in a wider range.
Compared with singlecylinder dryer with the same efficiency, its heat efficiency is improved about
50% and energy consumption saving doubles.
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, and double the service life than 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.
