Rotary Drum Kiln

what is rotary drum kiln?

AGICO is a well-known global provider of high-temperature industrial kiln solutions, specializing in creating rotary drum kiln systems that are both durable and highly effective for customers. We have been actively involved in the sector for decades, providing our global clients with reliable, efficient, and long-lasting core equipment for solid material thermal processing thanks to our exquisite engineering design and outstanding production skills.

The primary component of our rotary drum kiln, which is based on well-established drum technology, is a large rotating drum that is held up by a supporting roller system and an accurate ear shaft. The smooth and reliable rotation of the drum is guaranteed by a high-torque driving mechanism. The kiln body's layout is a little off-balance. Gravity and rotation work together to move the materials uniformly forward while tumbling and stirring, ensuring that any chemical reactions or physical changes are completed within the specified temperature curve and residence time.

High temperatures and heavy loads are common operating conditions for rotary drum kilns, placing a great deal of strain on the equipment's structural soundness and heat resistance. Using technologies like heavy steel plate rolling, special alloy welding, and advanced refractory material lining, AGICO, which has extensive experience in materials science and mechanical manufacturing, makes sure that the kiln body can sustain constant mechanical loads and thermal stress, ensuring the equipment's long-term stable operation.

We provide two technological options: direct heating and indirect heating, depending on the needs of the process. In situations when the material is permitted to come into touch with the flame, the direct heating type is very effective and appropriate. Through radiant walls or heat exchangers, the indirect heating type provides pure heat treatment, satisfying the needs of unique reactions or high-purity products. Based on your process objectives and the properties of your materials, AGICO will suggest the most dependable and economical option for you.

The five primary mechanical indicators of the kiln body materials-tensile strength, yield strength, elongation, impact toughness, and cold bending performance-are rigorously ensured by the use of 20G (GB5310) boiler steel plates and Q235-B (GB/T700) carbon structural steel in the main body of the rotary drum kiln. A crucial guarantee for your production, the whole rotating drum kiln uses an automated welding technique to guarantee the equipment structure's long-term use and reliable operation under high temperature loads around-the-clock.

The composite sealing technique of flexible graphite and rigid steel plate is used in the kiln tail of a rotary drum kiln. The high sealing performance of the kiln cylinder can be continuously maintained by this device's self-regulating function, which can effectively compensate for the axial and radial deformation of the kiln body. Its modular design directly lowers the system's air leakage rate, increases thermal efficiency, and guarantees operational safety while drastically lowering the complexity of equipment installation and subsequent maintenance.

For optimum performance, the rotary drum kiln system incorporates essential cutting-edge technology. While high-precision metering pumps and control valves maintain a steady fuel supply for reliable combustion, a hydraulic thrust wheel guarantees exact kiln alignment. Modern graphite block seals greatly increase the airtightness of the system. When combined, these developments lower energy consumption per ton of output, boost manufacturing capacity, and improve thermal efficiency.
