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 cement plant, located in Baishan City, Jilin Province, was equipped with new dry process clinker production line, and the production capacity was 3800 tons per day. As shown in Fig. 1, the field measurements was conducted in the flue gas from the preheater and the hot air out from the clinker cooler.
The Xuan Thanh Cement plant, located 75km south of Hanoi, has had the energy-efficient Cross-Bar Cooler operating successfully since 2017 when it produced its first clinker. Since then, the Cross-Bar Cooler has helped the cement-producing giant to achieve its production and energy efficiency goals, as well as keep maintenance to a minimum.
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
Apr 01, 2020· The grate cooler in the cement plant presented in Fig. 1 is investigated to demonstrate the applications of the HCM for moving packed beds. The cooling process of the cement clinker in the grate cooler satisfies Eq., where n = 9. 4.1. Boundary conditions.
In the cement manufacturing process large fans draw air through the kiln, precalciner, mills and filters to an ex-haust stack. Many smaller fans push the air into the grate cooler to reduce the temperature of the hot clinker leaving the kiln 1. All these airflows have to be adjusted and controlled as atmospheric conditions, process con-
