These are: (1) a study based on information from as many plants as possible to see if a pattern of buildup can be related to plant operating parameters and or raw material composition; (2) a laboratory study in which process operating conditions of the kiln ID fan were set up on a small scale to determine if the buildup problem seem in the field could be duplicated, and, if so, how could it be eliminated. Theories as to primary causes for the buildup have been divided into four primary groups: thermal, clinical, electrostatic and mechanical. All are discussed.

The basic system concept is composed of three distinct, but closely interrelated management tasks which are supported by software and hardware information systems. The ELCON (electric load control) module keeps track of usage online and indicates where and when corrective measures are necessary. This can be accomplished through automatic load switching or through preparation of instructions for manual intervention by the control room operator. Computerized energy data collection is the crucial point and a precondition for the second step goal: reduced specific energy consumption. It is shown that an energy cost reduction of between 3 to 6% may be expected.<<ETX>>","PeriodicalId":339195,"journal":{"name":"IEEE Technical Conference on cement Industry","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125275865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The project was conceived and executed during a time when plant utilization regularly exceeded 95% and cement shipments had reached all-time highs. A study was made of the preheater calciner performance with a view toward improving kiln output. The bottleneck in the system was the kiln induced draft fan, in connection with high pressure loss over the preheater. Pressures approached -30\" W.G. The study concluded that it should be possible to reduce the pressure loss over the preheater by introduction of the FLS-LP (low pressure) cyclone. The fact that the cyclones and calciner were replaced in an almost normal planned maintenance and kiln lining outage indicates that it is possible to provide nearly any such system with new cyclones, in one or more stages, to improve output, fuel economy and power consumption.<<ETX>>","PeriodicalId":339195,"journal":{"name":"IEEE Technical Conference on cement Industry","volume":"44 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131192014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This modernization is being accomplished by reorganizing the process around a new 5.4 m diameter by 90 m long rotary kiln with five-stage preheater and precalciner. The plant has thus increased its clinker production capacity from 3600 mtpd by three old kilns to 5000 mtpd with the new kiln in the first phase. It will be increased further to 7200 mtpd by the addition of a second preheater and a fourth grate in the cooler, both of which are provided for in the layout. The new production equipment concept consequently has to address the following particular circumstances: (1) requirement to phase out progressively, over a period of ten years, existing systems such as those for raw meal, fuels, clinker and cement; (2) requirement to integrate and phase in new systems in an optimal fashion; (3) implementation of a new concept including new material handling systems for the 7200 mtpd capacity. The raw mix control and the prompt gamma neutron activation analysis (PGNAA) instrumentation are discussed.<<ETX>>","PeriodicalId":339195,"journal":{"name":"IEEE Technical Conference on cement Industry","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114597197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The various origins of these surges were identified. The three major reasons for unstable operation are discussed. Looking at an unstable operation forced the engineers to look at the overall operation, not only a cyclone or a preheater. Solving this problem provided savings in the plant which included: a high level of reliability (98%) through consistent operation; high uptime on the kiln (reaching 90%); low heat consumption as a consequence of consistent operation; and safe operation by avoidance of tertiary air duct pluggage.<<ETX>>","PeriodicalId":339195,"journal":{"name":"IEEE Technical Conference on cement Industry","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115776059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A two-dimensional graphical method is presented for determining the actual ball charge within the total charge when parameters such as total volume, power draw and total mill charge weight are known. This information can then be used to develop a ball addition program to maintain optimum operating conditions, and to present to the mill operator a graphical description of the effect of the composition of the mill contents on the mill drive system and motor.<<ETX>>","PeriodicalId":339195,"journal":{"name":"IEEE Technical Conference on cement Industry","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122212219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
