Overview
Drum dryer is also called long drum dryer and drum dryer. It is the most common kind of dryer equipment in mining equipment. It has high production efficiency, convenient operation and easy maintenance. The dryer has a reasonable structure, excellent manufacturing process, high efficiency, energy saving, and convenient operation. It provides a one-stop solution for ease and convenience!
The machine uses reasonable operating parameters, the coal consumption and electricity consumption are reduced by more than 10-15% compared with the general dryer, and the output when the machine is increased by more than 10-15%.
working principle of rotary dryer
The rotating drum of the iron powder dryer is a slightly inclined and rotatable cylinder. Wet materials enter from the upper part of one end and dry materials are collected from the lower part of the other end. Hot air enters from the feeding end of the discharging end, and exits from the upper part of the other end. The barrel is equipped with a forward copy board, so that the material is continuously picked up and sprinkled during the rotation of the barrel, so that it is fully contacted with the hot airflow to improve the drying efficiency and move the material forward. The heat source of dry materials is generally hot air, high-temperature flue gas, etc. It can be selected according to the nature and quality requirements of materials.

- Large drying intensity, short drying time and large effective drying area;
- The structure is simple, the area is small, and it is easy to construct and maintain;
- Large processing capacity, thermal efficiency up to 60%;
- The drum dryer adopts “aligning roller device”, which greatly reduces wear and power loss
The drum dryer equipment is a kind of drying equipment that can dry a variety of materials and it’s structure is simple and reliable.
This dryer machine is mainly composed of:
★Rotary body: a rotating cylinder that is slightly inclined to the horizontal line, the wet material rotates with the cylinder in the cylinder, and the wet material flows to the lower end under the action of gravity and is dried and discharged;
★Lifting plate: The material rotates along with the rotating cylinder in the slewing body. During the full contact with the hot air flow, it is continuously sprayed by the lifting plate, so that the wet material forms a uniform curtain in the cylinder body, and the hot air flow Full contact for heat exchange. In order to achieve the purpose of further drying;
★Rotating device: The rotating device drives the rotating drum of the rotating drum dryer to make the wet material fully contact with the inner wall of the drum, and then conduct heat exchange to achieve the purpose of sufficient drying;
★Feeding box: The material enters the rotating body from the feeding box.
