Three Cylinder Drum Dryer & Features of ABC Machinery Dryer

What is a three-cylinder drum dryer?



A three-cylinder drum dryer is built with 3 concentric cylinders combined together according to some mathematical structure. By applying the heat-work principle, the lifting flights mounted on the inner wall and the feed guiding plates have been sophisticatedly designed. The wet material is moving in a spiral way by gravity, staying for a longer time inside the dryer while enhancing the heat exchange with hot air by fully spreading. In the specially designed three-cylinder structure, the inner and middle cylinders are wrapped by the outer one, forming a heat insulation system. The heat emitted by the inner and middle cylinders is again functioning in the heat exchange for material in the outer cylinder. The three-cylinder rotary dryer therefore realizes in decreasing the heat loss and increasing the heat exchange efficiency.

Advantages of a three-cylinder dryer:

1. Fast drying process, strong drying capacity As mentioned above, the scientifically designed lifting flights and the special three-cylinder arrangement guarantees that the wet material has a fully contact with the hot air, the innovative new drying process is applied to this dryer, the capacity can reach 5 tons dried material output per hour.

2. Energy saving, low cost Wholly automatically controlled, non-stop drying, overheated vapor makes possible to save 15%-20% more energy compared to the traditional dryer. You can choose fuel oil, gas and coal for the hot stove. As an example, the coal consumed for drying 1 ton material is 150kg-500kg.

3. Favorable drying result Speed adjusting feeder guarantees an even material feeding, ratio control burner for oil and gas, dynamic controller for coal burner, the temperature can be regulated, higher dried material quality.

4. Safe to people and environment Explosion protection device equipped to the pipeline; self extinguisher, negative pressure operation, no dust, no noise, high reliability, sound working environment.
