What is a three cylinder dryer

The triple drum dryer is an efficient and energy-saving product improved on the basis of the single drum rotary dryer. The following is a detailed introduction to the three cylinder dryer:

Structural characteristics

The three cylinder dryer reduces the external dimensions of the dryer body by replacing the single cylinder with three cylinders stacked together. Its overall structure is compact, reasonable, and simple. In order to facilitate the maintenance and replacement of worn parts, it is designed as an axial split in the middle and connected by bolts.

Working principle

The working principle of a three cylinder dryer is based on the principle of thermal power, and efficient drying of materials is achieved through the structural design of the inner, middle, and outer cylinders. The specific process is as follows:

• Material entering the inner cylinder: The material enters the inner layer of the rotary drum through the feeding device, achieving downstream drying. The material is continuously picked up and scattered under the inner layer of the plate, forming a spiral movement to achieve heat exchange, and then moving to the other end of the inner layer, entering the middle layer.
• Counter current drying in the middle layer: The material is continuously pushed in and out in the middle layer, with two steps forward and one step backward, fully absorbing the heat from the inner and outer cylinders, extending the drying time, and achieving a dry state.
• Multi ring travel of the outer drum: The material travels in a huge multi ring manner in the outer drum, fully utilizing the insulation effect of the outer drum and reducing heat loss. The materials that have achieved the drying effect quickly move out of the drum under the action of hot air, while the wet materials that have not achieved the drying effect cannot move quickly due to their own weight. They are fully dried in this rectangular plate to achieve the drying purpose.

Performance characteristics

• Efficient and energy-saving: The three tube dryer adopts advanced heat recovery technology and efficient heat conduction and hot air circulation design, which can greatly reduce energy consumption and improve drying efficiency.
• Large capacity continuous production: The three drum dryer has a large drying space and can process a large amount of materials simultaneously, meeting the needs of continuous production.
• Multi functional adaptability: The three tube dryer is suitable for drying various materials, such as chemical raw materials, food, medicine, etc. By adjusting operating parameters and equipment configuration, efficient drying of different materials can be achieved.
• Easy to operate and maintain: The control system of the three cylinder dryer adopts intelligent design, making operation simple and easy to understand. At the same time, its equipment structure is compact, with fewer vulnerable parts, making maintenance more convenient.

Application scope

The three tube dryer is widely used in various industries for drying materials such as slag, clay, coal, etc. In addition, it can also be used to dry granular materials within a certain humidity and particle size range, such as yellow sand, molding sand, slag, coal slag, small particle clay, etc. The moisture content of the dried material can reach below 1% -0.5%.

Installation and maintenance

• Installation: The three drum dryer should be installed on a horizontal concrete foundation and fixed with anchor bolts. During installation, attention should be paid to the verticality between the main body and the horizontal.
• Maintenance: Machine maintenance is an extremely important and regular task that should be closely coordinated with machine operation and maintenance. There should be dedicated personnel on duty to conduct inspections and ensure the normal operation of the machine.
