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 38, p494495), which may be helpful to you;In the present process, the system starts at a reduced capacity until such time as hot pellets enter the cooler The bypassed kiln gases are utilized for thermally balancing the system operating conditions until heat from the cooler is available The combination of cooler heat and burner heat results in lower process gas required through the kilnGrate preheater kiln system AllisChalmers Corporation
Unlike in ‘Straight Grate’ process a ‘Grate Kiln’ process employ only one burner situated at the discharge end of the Rotary Kiln Forced ‘Annular coolers’ are located at discharge end to uniformly cool pellet by an updraft of ambient air before transporting to storage siloProcess flexibility Pelletization process There are two main processes for producing iron ore pellets: The GrateKiln system and the straight grate system In the straight grate system, a continuous parade of grate cars moves at the same speed though the drying, induration and cooling zones get priceiron ore straight grate Rumes
