Grate coolers are widely used in cement industries to recover heat from hot clinker, coming out from the rotary kiln. This study focuses on improving the energy, exergy and recovery efficiencies of a grate cooling system through the optimization of its operational parameters such as masses of cooling air and clinker, cooling air temperature, and grate speed.
continuation of the cement-making process. These two points will lead to the application of a cooler system to provide the both aim. The clinker is then milled by the bullet mills. The powder obtained is sieved by riddling. Coarser particles from the mesh are returned to the mill. The final product is cement .
working in dry process pre-heater towers and on the areas under/around grate or cross bar cooling systems; posed by hot meal (the mixture of raw feed materials used in cement manufacture). Consequently, procedures for clearing and hot working in pre-heater towers systems and coolers, should be modified to take account of its recommendations.
Jul 01, 2017· The best practice of grate cooler for maximum heat recovery from hot clinker is the case with secondary air temperature of 1100 °C. However, examining the case studies indicated that the secondary air temperature has a range of 600–1100 °C. The Pinch Analysis has been implemented in each case study by considering two practices of grate cooler.
Extensively, the grate coolers are used in cement industry in order to recover heat from hot clinkers coming out of rotary kilns. This work focuses on the thermal performance of the clinker cooling system in a cement production plant employing the dry process. The aim is to study how the ambient

Re: GRATE COOLER. Hello Afsal, What you are describing is a common problem in clinker coolers and is generally called a "Red River". I found this passage in a book called "Clinker Coolers" by Hans E. Steuch (Chapter 3.8, p494-495), which may be helpful to you;-
The primary approach to this case study involved walk-through surveys of customer facilities and in depth interviews with customer decision makers and subsequent analysis of collected data. In addition, a basic review of the cement production process was developed, and summary cement industry energy and economic data were collected, and analyzed.
