| Abstract | For many years modifications to grate cooler technology have continuously developed. Many of the grate coolers supplied for the cement industry over the last 50 years include hydraulic drives. Continuous developments for the clinker cooler hydraulic drive have achieved a considerable improvement of operation, reliability and capacity. The following two plant modifications are good examples of the continued development of the hydraulic drive meeting the expectations of cement plant operators. The Cemento Votorantim S.A. Fabrica Santa Helena, Brazil decided in January 2001 to make a modification to their grate cooler drive on the 2nd grate. The plant replaced the existing mechanical drive with hydraulic drive including a grate motion control, compact swing supports and a moving frame guide. The Lafarge Cementos Maua, Matozinohos plant, Brazil also decided to make an improvement on their 2nd grate cooler drive to eliminate continuous kiln shutdowns due to grate mechanical problems and improve performance. The plant replaced the existing mechanical drive with a hydraulic drive including a local control box and compact swing supports in June 2000. Comparison is made for various parameters before and after modifications for: power consumption; air volume; clinker temperature; reliability; and grate control. Special discussion for different arrangements of grates in conjunction with hydraulic cylinders complete this paper. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
