Clinker Coolers
The purpose of a Clinker Cooler is to cool the clinker. From an engineering viewpoint, cooling is necessary to prevent damage to clinker handling equipment such as conveyors.From both a process and chemical viewpoint, it is beneficial to minimise clinker temperature as it enters the clinker mill. The clinker gets hot in the mill and excessive mill temperatures are undesirable. It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials.From a cement performance viewpoint, faster cooling of the clinker enhances silicate reactivity.
The cooled clinker is then conveyed either to the clinker store or directly to the clinker mill. The clinker store is usually capable of holding several weeks' supply of clinker, so that deliveries to customers can be maintained when the kiln is not operating.
