High-efficiency cement cooling
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 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction. The ideal temperature to further avoid moisture attraction while in storage (due its hygroscopic properties) is in the range of 50ºC to 60ºC.
Solex moving bed heat exchange technology is capable of handling any relatively free-flowing powder or crystalline bulk solids, making it the perfect candidate to cool cement, while using up to 90% less energy compared to direct cooling methods.
With a heat transfer area of almost 10 times that of traditional vertical powder coolers combined with up to 75 per cent less water usage, our plate-based technology offers high efficiency, effectiveness and reliability.
Proven technology through pilot testing
Extensive pilot testing carried out at the Lafarge cement plant in Exshaw, Alberta, Canada has proven that Solex technology can effectively and efficiently cool cement as part of the finish grinding process, and can provide designs for full production capacities of 50 to 200+ tons per hour.
