Rotary drum dryer machine
Details
Product Description
Rotary drum dryer is one of the traditional drying equipments. It has reliable operation, large operational flexibility, strong adaptability and large processing capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin, sugar and other fields. Its diameter is Φ1000-Φ4000mm, the length is determined according to the drying requirements.
Application

working principle
The drying machine is mainly composed of rotating body, lifting plate, transmission device, supporting device and sealing ring etc.
The dryer is a cylinder which is slightly inclined to the horizontal direction. The materials are fed from the higher end. And the high-temperature hot gas flows into the cylinder with the materials. As the drum rotates, the materials run to the lower end due to the effect of gravity. Lifting plates are installed on the inner wall of the cylinder, and the materials will be picked up and sprinkled to increase the contact surface between the materials and the airflow to improve the drying rate and push the materials forward. The dried materials can be collected from the bottom of the drum.
Advantages
- The raw material of drum is boiler steel, which is more resistant to high temperature, has a long service life and is not easily deformed.
- The ring gear, ring roller and gear box, etc, are all made from qualified raw materials. Furthermore, these important components are all heat treated. After heat treating process, the properties such as hardness, toughness and abrasive resistance are all improved. Besides, these important components are produced via CNC machine tools, to keep better accuracy.
- Strong scalability, even if the output increases slightly, there is no need to replace the equipment.
- Wide range of applications
- Different type heat sources for customer option
