GRATE COOLER - Page 1 of 1 - International Cement Review

It is recommended that the cooler inlet grate width not exceed 2.5 m for kiln capacities up to 2,500 metric tons per day of clinker. Figure 3.8.17 shows that some air holes in corner grates are blanked off. Corner areas often have a low clinker load which results in heavy air channeling and bypassing the clinker load.
