Opportunities clearly exist for cost reduction, increased productivity and greater profitability. Increasingly sophisticated process control and plant optimization systems provide raw data in great abundance. Yet, too often, individual process control systems amount to isolated \"information islands\" that lack a means of integrating related data. At the same time, powerful business computer systems are providing an increasingly detailed picture of financial and marketing conditions. New cement-specific information management systems (IMS) are being developed to integrate production, process, energy, environmental, quality and key business information into a consistent relational database. By compiling, condensing and providing access and analysis tools, IMS systems overcome traditional barriers of information access within automation and information systems. Process, production and business managers can have the information they need presented to them in the most useful form on their desktop personal computer. IMS provide tools for plant managers that are unavailable from the process control system. Similarly, they provide a detailed database for use by enterprise managers that cannot be provided by the business control computer system. This way IMS systems close the functional gap between these two systems.","PeriodicalId":373006,"journal":{"name":"Proceedings of 38th Cement Industry Technical Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116881086","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}

Standen","doi":"10.1109/CITCON.1996.506011","DOIUrl":"https://doi.org/10.1109/CITCON.1996.506011","url":null,"abstract":"Large dual electromechanical drive systems have been shown to often experience vibration problems due to both the high inertia of the components of these systems, and the large number of resonant frequencies experienced by these drives. Hydraulic drives, by comparison, are extremely low inertia drives, that have fewer resonant frequencies and benefit from the damping characteristic of the hydraulic oil used to transmit power. Additional benefits include the ability to isolate components while operating the drive and smooth speed control starting at extremely low speeds and full rated torque. This paper outlines the vibration problems that were experienced in a dual drive of a 655' long with 22' and 19' diameter section rotary cement kiln between 1979 and 1993. A number of analytical and empirical studies were performed and various modifications were made or considered to reduce the vibration in the drive train. Finally, in 1994 when the existing drive reached the end of its life, it was replaced with a hydraulic system. The methods both used and considered to reduce the vibration are discussed, as well as the critical elements in deciding on a hydraulic drive and the design issues encountered including questions of drive efficiency, reliability, maintenance and control. Results to date of the hydraulic drive are discussed, including the elimination of the vibration problem and added flexibility in speed control.","PeriodicalId":373006,"journal":{"name":"Proceedings of 38th Cement Industry Technical Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130967151","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 short-term needs of the facility must be satisfied as well as the long-term strategies of the organization. The Lafarge Corporation Alpena Plant was faced with such a decision regarding their Kiln 19 clinker cooler. A change in raw materials was expected to increase production rates by 10%. The existing oscillating grate cooler did not have the capacity to handle the additional capacity. Other factors involved in the decision to replace the clinker cooler were escalating maintenance costs, obsolete parts, and poor operational efficiencies. The new clinker cooler utilizes air beam technology and has proven to meet all the requirements of the plant. The anticipated production increase was exceeded without negatively impacting the performance of the air beam cooler. Audited cooler losses were excellent at 207 MJ/t/sub KK/ (49 kcal/kg/sub KK/). Power consumption results were 6.6 kWh/t/sub KK/. Clinker discharge temperatures after the breaker are lower than 56/spl deg/C above ambient. The fuel consumption reduction resulting from the cooler installation was approximately 3%.","PeriodicalId":373006,"journal":{"name":"Proceedings of 38th Cement Industry Technical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131222411","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}

Today, a retail electric customer still purchases a bundled product (delivered electric energy) from its native electric utility. However, in a truly competitive retail environment, an end-user will be able to competitively source its purchase of various unbundled products from different suppliers. Types of unbundled products that should be available include demand and energy, load following, operating reserves, reactive power, and others. Electric energy storage, which is being developed using superconductor technology, could play a vital role in the developing competitive electric market. Superconducting magnetic energy storage devices can presently store electric energy up to several megawattseconds, but new advances are creating the possibility of storing thousands of megawatthours. This increased energy storage would enable end-users to peak shave and displace traditional sources of power when economically appropriate as is currently done with gas storage.","PeriodicalId":373006,"journal":{"name":"Proceedings of 38th Cement Industry Technical Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126685336","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}

Dramatic increases in participation by the industrial sector have been in evidence. However, the cement industry, including cement manufacturers, equipment manufacturers, and related organizations, has not yet become an active participant. Why should the cement industry embrace the Internet? What are the potential benefits, both economic and otherwise? Electronic mail, providing efficient communications among its members, is only one. Others include the sharing of research and promotional information; educational programs (distance learning) on cement and concrete via the Internet; access to timely information, including regulatory and industry information; and electronic discussion groups in which technical problems and ideas can be addressed and discussed. Before participation becomes a reality, several things need to occur. Industry leaders must be convinced that there is sound economic reason to invest the time and money in their companies' participation. They also need to be educated on its use and to see how other related industries are using it. And they need to provide input on the specific types of information and services that are needed. This presentation outlines the potential benefits of the Internet, demonstrates both existing and developing applications, and describes specific efforts toward a unified presence by the cement and concrete industries.","PeriodicalId":373006,"journal":{"name":"Proceedings of 38th Cement Industry Technical Conference","volume":"562 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126718324","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}
