2、imum availability of the kiln installation and to verify that the kiln operates within the load and stress parameters laid down by the kiln designer. Todays state of the art methods of inspection performed during normal operation of the kiln are based on advanced measuring techniques and evaluated b

3、y highly experienced kiln specialists. Although the vast majority of cement plants employ a very experienced maintenance staff, it is not economically and technically viable for the individual plant to invest in the measuring instruments and develop the computer software required, acquire and mainta

4、in the skills necessary to perform these advanced inspections, process the data and evaluate the results. Therefore it is an accepted practice in the cement industry worldwide to call on an outside company to carry out these comprehensive kiln inspections at regular intervals. F.L.Smidth F.L.Smidth

5、is the worlds largest supplier of rotary kilns, spare parts and services to the cement industry. With more that 120 years of experience as kiln designers, F.L.Smidth possesses a huge technical know-how on rotary kilns and employs a group of highly experienced field engineers, who work daily as kiln

6、specialists at cement plants all over the world backed up by the entire F.L.Smidth organisation. The Hot Kiln Alignment method was introduced into the cement industry in 1981 allowing a full inspection of the kiln to be performed during normal operation. Since then, F.L.Smidth has continuously updat

7、ed and improved the method, measuring instruments and computer software to provide our clients with the best possible tools to evaluate the consequences of the kilns present operating condition in respect of the availability. The F.L.Smidth concept The inspection concept innovated by F.L.Smidth focu

8、ses on the following four elements: Kiln axis Kiln shell ovality Axial balance Kiln crank The root causes of the vast majority of the failures of kiln installations originate from one or more of these elements, thus posing a serious threat to the availability of the kiln. In addition, the F.L.Smidth

9、 concept includes a thorough inspection of the drive station, kiln shell profile analysis, and a general inspection of the mechanical condition of the other key kiln components. Very often the load condition of a kiln changes over the years due to e.g. Increased capacity, change of fuel and/or chang

10、es of refractory lining quality. To compensate for such changes, F.L.Smidth recommends that the kiln be recalculated based on the present load conditions and that the optimum kiln axis be determined taking the load distribution between the individual supports and the stress levels in kiln shell,tyre

11、s and rollers, as well as the bearing loads into consideration. F.L.Smidth inspection types F.L.Smidth markets the following three standard inspections covering all types of rotary kilns: Comprehensive kiln inspection Two-support kiln inspection Hot kiln alignment check The F.L.Smidth standard inspe

12、ctions consist of individual modules,most of which are optional, enabling the client in co-operation with F.L.Smidth to tailor an inspection to meet his specific needs.The results of the F.L.Smidth inspection are presented in a written report and/or on a CD-Rom, with recommendations of measures to b

13、e taken. Additionally, any adjustments to the kiln recommended by F.L.Smidth can, at the clients request, be supervised and verified by an F.L.Smidth field engineer in continuation of the inspection. Benefits The comprehensive kiln inspection performed on a regular basis in co-operation with F.L.Smi

14、dth provides the client with the knowledge necessary to prolong the lifetime of the refractory lining and expensive kiln components and reduces the risk of unscheduled stoppages, thus ensuring high kiln availability. Empirically, the payback time of a comprehensive kiln inspection is very short as the expenditure on this inspection is very marginal as compared with the
