GRATE COOLER<\/h1>\n\n\n\n

Achieve efficient cooling<\/h3>\n\n\n\n

The aim of any cooling system is to cool the clinker as quickly as possible, to set and maximize C3S content. Simultaneously, it is important to capture and re-use the heat liberated by this process. In the grate cooler, the clinker enters at a temperature of around 1,200\u00b0C, rapidly spreading its heat into the grate and surrounding refractories. High refractoriness, high abrasion resistance and resistance to thermal shock are necessary, especially at the clinker downfall and bull nose.<\/p>\n\n\n\n

The cooler is effectively divided into two zones \u2013 the \u2018hot\u2019 zone and the \u2018cold\u2019 zone.<\/p>\n\n\n\n

In the \u2018hot\u2019 zone, from the clinker downfall to the bypass duct and partition wall, the goal is to rapidly liberate heat and route it back to the preheater via the tertiary duct.<\/p>\n\n\n\n

In the \u2018cold\u2019 zone, when clinker temperature has dropped below 800\u00b0C, it is most important to achieve a uniform temperature decline throughout the clinker body. Abrasion is the worst problem here.<\/p>\n\n\n\n
