Pdfgrate Cooler In Cement Plant In Plate Types. We manufacture this critical heat resistant castings component for the cement plants . these heat resistant castings are used for working temperature upto 1100 degree celcius. following are the various types of castings that are needed by the cement plant cooler grate plate
(75.53%) at this stage of the clinker production process. This study revealed that the grate cooler efficiency estimated through heat consumption balances conformed to the designed standard. Also, the cooler optimal performance has made more heat available for drying of material at the pre-heater and Vertical Roller Mills (VRM) during grinding.
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.
The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.
We supply complete automation systems based on DC drives, AC drives, Slip Power Recovery Systems, process controllers, HMIs, Instrumentation and plantwide network. DC drives for kiln.. AC drives for cooler fans, grate coolers, separators, stacker reclaimers.
Providing details of the processing equipment of cement kiln systems – Safety and Process Control of Cement Kiln ... burners and grate coolers ... The course consists of theoretical classroom training, exercises, case study, work section and calculations. Documentation.
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.
The course content will be suitable for a wide range of personnel within a cement manufacturing company including junior/middle management, technicians, production and control room staff, etc and also for others who wish to gain a comprehensive understanding of the complete cement manufacturing process.
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

2. Cement Industry: An Introduction
An energy intensive industry consuming about 4GJ per tonne of cement produced.
In dry process cement plants, nearly 40 percent of the total heat input is rejected as waste heat from exist gases of pre-heater and grate cooler.
In India, .
Energy audit and waste heat recovery system design for a cement rotary kiln in Ethiopia: A case study 2985 grate cooler to cool the clinker. The cooled clinker is then transported to the clinker concrete silo for storage. The current study focuses on this sub-process [9]. Figure 2. Typical clinker production sub-process.
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.
Techno-Economic Study of CO2 Capture Process for Cement Plants Carbon dioxide is considered to be the major source of GHG responsible for global warming; man-made CO2 contributes approximately 63.5% to all greenhouse gases. The cement industry is responsible for approximately 5% of global anthropogenic carbon
