Three drum Dryer is an improved version based on a single drum dryer with advanced German technology, mainly composed of three concentric circles, and is used to dry granular materials with certain moisture and particle size.
three-drum dryer is also known as a three-cylinder dryer or a three-drum dryer. It is an improved version based on a single drum dryer and is supported by modern and advanced German technology. The three-cylinder dryer is mainly composed of three concentric circles of different diameters. Compared with the traditional drum dryer, the three-drum dryer has better sealing technology and is equipped with a more scientific machine. This dryer is usually used to dry granular materials with a certain moisture and a certain particle size range. For example, a three-drum dryer can be used to dry clinker, sand, molding sand, slag, cinder, fine-grained clay, high-temperature resistant and dusty particles.
Three-drum dryer is widely used in building materials industry, metallurgical industry, mineral processing industry, chemical industry, cement and other industries. It is suitable for the drying of various granules and powders in the above industries. After drying, the humidity of the material can reach below 1%. Some application examples of three-drum dryers:
Radiation, convection, and heat conduction are mainly used in the drying process. The dryer is set at an angle to take advantage of gravity. When the hot air in the oven reaches the set temperature, the dryer works according to the order of the PC system. The wet pellets are then evenly fed into the inner layer by the feeder and carried away by the gale. The wet material is spirally conveyed through the fixed shovel plate. Next, the material moves to the other end of the oven and into the middle layer. This time, the wet powder inside leaned against the blower and moved forward, taking two steps back. In the middle layer, the heat from the inner and middle layers is fully utilized, which increases the drying efficiency to the optimum. Finally, the dried material reaches the other end of the middle layer and enters the outer layer in a rectangular and multi-loop pattern. Drying to solidify the moisture of the granular material is blown out of the dryer. The rest move more slowly due to their weight and dry again in the outer layer to the desired humidity. In this way, the drying process is realized.
Working Principle of Three-Cylinder Dryer
Compared with traditional dryers, three-drum dryers have obvious advantages;
There are types of drum dryers, such as single drum dryers, double drum dryers, triple drum dryers, and air dryers. It’s always confusing for customers to make decisions. Take a single-drum dryer and a three-drum dryer as an example to clarify how to choose the right dryer.
