Rotary drum dryer is one of the traditional drying equipment, and it has reliable running, flexible operation, strong adaptability, and high production capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin and sugar. Its diameter is 1000 4000, and the length is depended on the dry requirements. In the center of the rotary drum dryer, increasing the dispersion mechanism can be avoided; The wet material entering into the drying cylinder is repeatedly copied and left off by the copying plate on the cylinder wall, then in the process of falling, the material is broken into fine particles by dispersator. In this way, the contact area increases greatly, and the material fully contact with the hot air, thus the effect of drying is achieved.
The rotary drum dryer is mainly composed of rotary body, lifting blade, transmission device, supporting device and sealing ring. Dry wet materials are sent to hopper by belt conveyor or bucket elevator, and then by hopper feeder the material enters the feeding end through the feeding tube. The slant of the feeding pipe is larger than the natural inclination of the material, so that the material flows into the dryer smoothly. The cylinder of dryer is a rotating cylinder slightly tilted to the horizontal line. The material is added from the higher end, the heat carrier is entered at the low end with the material in reverse contact; there are also heat carriers and materials that flow into the tube together. With the rotation of the cylinder the material is operated by gravity to the lower end. In the process of moving forward, the wet materials can be directly or indirectly heated by the heat carriers, so that the wet materials can be dried and then be sent out by belt conveyor or spiral conveyor to the discharge end.
Weve built a reputation on building the best rotary dryers in the industry. All of our dryers are custom designed to suit the unique processing needs of your material. Whether you require low or high inlet temperatures, short or long residence times, counter current or co-current flow, FEECOs design team can design a rotary drum dryer for your application.
Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.
The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency. When working with agglomerates, the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules.
All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.
Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include:
Unlike direct dryers, indirect dryers do not rely on direct contact between the material and process gas to dry the material. Instead, the rotating drum is enclosed in a furnace, which is externally heated. Contact with the heated drum shell is what dries the material.
