[0002] Grate cooler is an important main machine in the clinker burning system of cement plant. Its main function is to cool and transport cement clinker, and provide hot air for rotary kiln and decomposition furnace, etc. It is the main equipment for heat recovery in the burning system. Grate cooler is a quenching cooler. After the clinker enters the cooler from the kiln, it is spread on the grate plate to form a material layer of a certain thickness. The cold air blown in passes through the material layer moving on the grate bed in a perpendicular direction to cool the clinker quenchly.
