Structural Composition:
It is mainly composed of a rotary body, lifting plates, a transmission device, a supporting device, sealing rings, and other components.
Working Principle:
The rotary dryer is a cylinder slightly inclined to the horizontal direction. The material is fed from the higher end. Depending on the drying characteristics of the material, high-temperature flue gas can enter the drum either in co-current flow with the material or in counter-current flow. The inner wall of the drum is equipped with many lifting plates. As the drum rotates, the material is continuously lifted and evenly scattered, bringing the material into contact with the high-temperature flue gas. The moisture continuously absorbs heat and turns into steam, which is discharged from the drum along with the flue gas through the dust removal system. Under the action of gravity, the material gradually moves toward the drum outlet during the scattering process and is discharged from the drum.
Product Performance Features:
1. Wide range of applications: Widely used in mining, mineral concentrate powder, tailings, coal, metallurgy, chemical industry, light industry, building materials, food, and other industries. Suitable for powdery, granular, and highly viscous, high-moisture materials with strong adhesion. The company can tailor and design different drying solutions for different materials.
2. High heat exchange efficiency: Reduces energy consumption and heat loss. The rotary dryer produced by our company adopts full-machine insulation materials for thermal insulation, improving thermal efficiency and reducing heat loss. Based on the properties of the material, the internal lifting method and zones of the drum are scientifically configured to extend the residence time of the material inside the machine body, improve thermal efficiency, and reduce the loss of high-temperature gas.
3. High operational flexibility: The single machine adopts an automatic control system, which can adjust the feeding and discharging speed, heat and temperature supply, main machine speed, and exhaust fan, etc., at any time according to different material properties, easily achieving optimal working conditions.
