2.0 * 5.0 m Big Sale Sand Drying Machine, Three Drum Rotary Dryer

Three Drum Dryer

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 thecylinder, 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.

Charteristics 

1.Energy saving, the heat efficiency can be up to 80%,

2. Save space, just the 1/3 of single cylinder dryer.

3. Friction transmission, lower noise

4. Low dust pollution

5. The cylinder and flying plate use alloy steel, double service life than normal steel.

6. Can use coal, gas or oil as fuel.

Working Principles

1.The material first goes into the inside drum, because there are the spiral shape boards fixed in the drum, when the dryer make rotary working, the spiral shape board will stir the material and make the material do movement. three return dryers

2.When the material reaches the right side of the drum, it will go into the second drum for further drying.

3.The same working principle, the material then goes into outside drum, during the drying working process, thematerial will make three times drying, so the material can be dried completely in this process.
