A three tube dryer is an efficient drying equipment widely used for drying various materials.
1、 Working principle
A three cylinder dryer consists of three concentric cylinders of different diameters nested together. The material enters the innermost cylinder from the feeding end, and as the cylinder rotates, the material is continuously lifted and scattered, fully contacting with hot air for heat exchange. Hot air enters from the inner cylinder, passes through the middle cylinder and the outer cylinder in sequence, exchanges heat with the material, and is discharged from the discharge end, taking away the moisture in the material, thus achieving the drying of the material.
2、 Main features
Efficient and energy-saving: The unique three tube structure design increases the contact area between materials and hot air, improves heat exchange efficiency, and reduces energy consumption. The hot air forms an effective circulation between the three cylinders, fully utilizing the heat energy and further reducing the drying cost. Small footprint: Compared to traditional single drum dryers, triple drum dryers have a smaller footprint with the same processing capacity, saving space.
Strong adaptability: It can adapt to materials of different properties, including various forms such as powder, particle, block, etc. It also has a good drying effect on materials with high humidity and high viscosity. Stable and reliable operation: The equipment has a compact structure, good coordination between various components, and low vibration and noise during operation. Adopting advanced transmission and idler devices to ensure long-term stable operation of the equipment.
High degree of automation: Equipped with advanced control systems, it can achieve functions such as automatic feeding, automatic temperature and wind speed adjustment, easy operation, and reduce manual intervention.
3、 Application Fields
Mining field: used for drying materials such as ore, mineral powder, tailings, etc., to improve the quality and added value of minerals.
In the field of building materials: drying building materials such as cement, gypsum, fly ash, sand, etc. to provide good conditions for subsequent processing and use.
Chemical industry: drying chemical raw materials, fertilizers, pesticides and other materials to ensure product quality and stability.
In the field of agriculture, it is used to dry agricultural products such as grains, feed, seeds, etc., extend their storage time, and improve product quality.
4、 Precautions
Material characteristics: When using a three cylinder dryer, it is necessary to fully understand the characteristics of the material, such as particle size distribution, humidity, viscosity, etc., in order to select appropriate drying parameters and equipment models.
Hot air temperature and wind speed: Controlling the temperature and wind speed of the hot air is the key to ensuring the drying effect. Excessive temperature may cause material deterioration or damage to equipment, while low wind speed can affect heat exchange efficiency.
Equipment maintenance: Regularly maintain the three drum dryer, check the operation of the transmission device, supporting wheel device, sealing device and other components, timely clean up the accumulated materials and debris inside the equipment, and ensure the normal operation of the equipment.
Safe operation: When operating equipment, it is necessary to strictly follow the safety operation procedures to prevent accidents from occurring. For example, during the operation of the equipment, personnel are prohibited from approaching rotating parts to avoid mechanical injuries.
