Three-drum Dryer

The three-drum dryer is a widely used equipment in the industrial field. It places powdery, granular, blocky or gelatinous materials in the dryer and uses hot air to dry them, so that the moisture in the materials evaporates, thereby achieving the drying effect. The three-drum dryer has the following advantages:

Good drying effect: The three-drum dryer uses three cylinders for drying, which increases the contact area between the material and the hot air and improves the drying effect. At the same time, the dryer is equipped with a stirring device, which can evenly distribute the materials in the dryer, so that the hot air can fully contact the materials and accelerate the evaporation of moisture, thereby achieving a better drying effect.

Wide range of application: The three-drum dryer can be used for drying a variety of materials, including powdery, granular, blocky or gelatinous materials. Different types of materials can choose different dryer cylinders for drying as needed, which is more flexible and convenient.

High drying temperature: The three-drum dryer uses hot air drying to provide a higher drying temperature. High temperature drying can accelerate the evaporation of moisture, shorten the drying time, and improve the drying efficiency.

Large production capacity: The three-drum dryer has a longer cylinder and can accommodate more materials for drying at the same time, so it has a larger production capacity. This is very important for the industrial field and can meet the drying needs of large quantities of materials. Easy operation: The three-drum dryer adopts an automatic control system, which can monitor and adjust the temperature, humidity and other parameters of the dryer in real time, and the operation is simple and convenient. At the same time, the dryer is equipped with lights and cleaning devices, which can easily observe and clean the materials in the dryer, improving the use efficiency of the equipment. Energy saving and environmental protection: The three-drum dryer adopts hot air drying during the drying process, and the hot air can be recycled, reducing energy consumption. At the same time, the dryer is equipped with a dust removal device, which can effectively reduce dust pollution in the material and the impact on the environment, meeting environmental protection requirements. Stable mechanical structure: The three-drum dryer adopts a new design and manufacturing process, with a stable mechanical structure and reliable operation. The equipment is equipped with an explosion-proof device and an automatic fault alarm device to ensure the safety and reliability of the equipment.

Product Details

Three-drum dryer is a common industrial drying equipment, widely used in food, chemical, agricultural products and other industries.

Three-pass dryer is a high-efficiency combined three-drum dryer. Large three-drum dryers are usually 6 to 7 meters long and are divided into two structural forms: straight and conical. The flow of materials is driven by the blades (i.e. guide plates) in the drum that rotate with the drum to move the materials forward. It is suitable for straight or conical structures. The three-pass dryer is composed of three concentric cylinders of different diameters nested together, rather than interlocking, which is a chain. This special structural form determines the size of its output, so this new type of dryer is also called a three-pass dryer. LJSH high-efficiency combined three-drum dryer has a compact structure and a small footprint. It is half the footprint of a single-drum dryer with the same output. It is reliable, has low energy consumption, high thermal efficiency, good material drying effect, is easy to realize automatic control, and requires fewer operators.

The three-drum dryer is mainly used to dry granular materials within a certain humidity range, such as yellow sand used in the dry mortar industry, various specifications of molding sand used in the foundry industry, blast furnace slag used in the building materials cement industry, small-grained clay, and small-grained materials used in the chemical industry that do not undergo chemical changes and are not afraid of high temperatures and smoke. According to the requirements of different industries for the final moisture content of the dried material, the moisture content of the dried material can reach below 1-0.5%.
