Operating for extended periods under significant stress, rotary kilns don’t have it easy. FLS rotary kilns take it in their stride, offering unparalleled reliability and longevity across the full range of operating conditions and applications.
Ranging in diameter from 1m to 6.5m and in length up to 200m, our rotary kilns deliver effective thermal treatment of a wide range of materials. We also offer a comprehensive selection of kiln system auxiliaries, allowing us to deliver complete rotary kiln systems tailored to your specific needs and application.
FLS is your single-source supplier of pyroprocessing equipment and systems. Our in-house test centre is home to a wide range of test and pilot-scale equipment, allowing us to simulate complete processes and ensure the best possible system design and equipment selection. Various analysis options are available at the test centre, providing rapid results to support your test campaign.
We provide commissioning/installation support and supervision to ensure optimal system start-up. A comprehensive range of aftermarket services continues to ensure your pyro-equipment maintains market-leading performance over its operating life. These include equipment inspections, troubleshooting and optimisation, high-quality spare parts, replacement of worn components, retrofits, modifications, and training. We also support conversions to alternative energy systems, such as hydrogen firing, oxyfuel combustion, and electing heating.
Rotary kilns feature guards, heat shields, thermocouples, and control systems to protect personnel and equipment.
Engineered for reliability and long-lasting performance.
The simple, heavy-duty construction and design of our kilns requires minimal maintenance while ensuring efficient performance. Shell internals are designed to optimise heat transfer, whatever the process, while mid-kiln fuel/air injection allows effective control of the reaction temperature.
A fully floating cast or forged riding ring ensures smooth operation while proprietary sleeve bearings minimise vibration and hydraulic/mechanical thrust devices maintain alignment. Shell materials are also tailored to the application to control wear. The result is lower operating stress and a rotary kiln that lasts 25 years or more.
FLS rotary kilns incorporate a range of safety features to effectively protect your people and equipment, including drive/coupling, girth gear, and support roller guards, heat shields, kiln drive roll back control and maintenance brakes, support bearing thermocouples, and kiln position indication.
