A strong, successful and healthy relationship with the original equipment supplier (OEM) has allowed the Company to implement new technologies to drive the operation of the equipment throughout the 30 year history of the production line. Recently, the Company chose the OEM in undertaking a number of upgrades to achieve an increase in capacity and improved efficiency. This paper highlights the steps taken during a 2-phase upgrade to achieve 2,200 STPD (2,000 MTPD) of clinker and allow the Company to remain at the forefront in implementing new technologies in the industry.","PeriodicalId":422446,"journal":{"name":"2014 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114737710","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}

Long used for providing leading kVARs for PF improvement and helping with the device switching in Load Commutated Inverter (LCI) drives, these machines are efficient prime movers for large Mill applications. Both in motor efficiency and in low base speed configurations the synchronous motor has advantages of lower current and higher efficiency. Often used in large Mills in the cement and mining industry, these motors were driven by LCI variable-frequency drives (VFDs) or used with direct start with a clutch system that would synchronize the motor first to overcome low starting torques. This paper reviews various Mill drive configurations and improved synchronous motor characteristics when used with more advanced Current Source Inverter (CSI) drives. It will also review the different synchronous motor excitation types and resulting performance characteristics with VFD control for new or retrofit installations.","PeriodicalId":422446,"journal":{"name":"2014 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127941736","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 new regulations called for continuous monitoring for mercury, particulate matter, total hydrocarbon emissions, and hydrochloric acid. The company took the strategy to install equipment in anticipation of a September 2013 compliance date and use any additional time that might become available to refine techniques. These installations were being commissioned in the fall of 2012 and early in 2013. This paper discusses the process utilized to design and install various continuous emissions monitoring systems (CEMS), lessons learned since the installations, and developments in how industry is attempting to comply with regulations where the Performance Specifications still are not fully developed, or the technology is not commercially available to demonstrate compliance.","PeriodicalId":422446,"journal":{"name":"2014 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"275 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123716250","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}

Many of the electrical regulations, which are set out at 30 C.F.R. Part 56.12, can be fairly characterized as simplistic, broad, dated and confusing. MSHA often reads requirements or prohibitions into its regulations that are not evident from the language of the regulations. Mine operators need to understand that the regulations are essentially interpreted by MSHA using a “reasonably prudent person” standard. An operator's failure to anticipate MSHA's changing expectations for a reasonably prudent person can result in substantial penalties, closure orders, abatement predicaments and even penalties against its management. Supervisors and managers with responsibility for electrical systems, particularly those using newer technologies that are beyond MSHA's expertise, need to be proactive in anticipating, avoiding and addressing creative MSHA enforcement.","PeriodicalId":422446,"journal":{"name":"2014 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128512002","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}

Early introductions were in the metallurgical and power industries beginning in the late-seventies and early-eighties. By the second-half of the nineties, LPHV baghouses were being installed on cement kilns and clinker coolers. And by 2005 cement kiln ESPs were being converted to LPHV pulse-jet baghouses. Lower maintenance and operating costs have been significant factors in selection of this technology approach. Details of operation and maintenance with LPHV pulse cleaning are presented in this paper.","PeriodicalId":422446,"journal":{"name":"2014 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125561762","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}

Important reserves of high quality limestone guarantee long life for the new installation which is designed to fulfill both the present and future needs of a sustainable production - in particular related to the minimization of local environmental impacts and total energy consumption. The new line combines several innovative solutions, some of which have a limited number of installations (such as the installation of a roller press in the finishing configuration of the raw meal grinding installation) while some are entirely unique to the cement industry (such as the installation of a ceramic bag filter for the direct dedusting of the cooler vent air and the reuse of its hot, clean air for multiple energy recovery systems).","PeriodicalId":422446,"journal":{"name":"2014 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132592679","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 case study indicates how a rigorous QC based approach to the production of solid alternative fuels in cement kilns was developed that contributes to maximum TSR. PEF differs from conventional solid alternative fuels in that production begins with the best material possible as the main feedstock and then selected industrial and commercial by-products of known and consistent composition are added to improve the overall mix and thus achieve the desired quality specifications. The PEF concept allows for maximum thermal substitution rates at either a main burner or in a calciner because the product is matched to the specific cement kiln needs and limits.","PeriodicalId":422446,"journal":{"name":"2014 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129823751","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}
