Three-drum Dryer

A three-drum dryer, also known as a three-cylinder 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.

• Capacity: 5-100 t/h
• Dried Moisture(%): 12-15% (Adjustable)
• Heat Source: biomass, natural gas, diesel, coal, etc.
• Application: Suitable for drying the sand, silica sand, fly ash, mineral slag and other material.

What is Three-Drum Dryer?

 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.

Applications of Three-Drum Dryer

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:

• Yellow sand in the dry mortar industry and full-size artificial sand in the foundry industry
• Sandblasted surface slag, limestone and quartz/silica sand in the building materials and cement industries
• Chemical industry residues, concentrates and tailings
• Coal slime, raw coal, flotation coal concentrate and blended coal in the coal industry
• Other wet granular materials such as metal powder, fly ash, river sand, gypsum, etc.

How Three-Cylinder Dryer Works?

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

The structural advantages of the zoned three-drum rotary dryer

Compared with traditional dryers, three-drum dryers have obvious advantages;

• The discharge temperature is less than 50 degrees, and it can directly enter the base without cooling. In addition, the low emission temperature will extend the life of the dust collection system.
• There is no air leakage, which completely solves the difficulty of sealing. It can be installed in 2 hours.
• The thermal efficiency is up to 80% (compared to 32% for conventional single-cylinder dryers), an increase of 48%.
• Compared to a single-drum dryer, the occupied area is reduced by about 50%, so the land investment is reduced by about 50%.
• The coal consumption is 1/3 of that of a single-cylinder dryer, and the energy saving is 40%. The standard coal consumption per ton of material processed is less than 9 kg. Small dryers save 50-100 million yuan per year, and large dryers save 100 million-200 million yuan per year.

How to Choose a Suitable Dryer?

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.
