The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. recommendations vary but it is generally accepted that with mill outlet temperatures of around 110 c – 120 c, cooling to below 80 c is necessary to avoid this reaction.
The milling process generates heat 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.
