similarly, it is important to base the cooler efficiency calculations on realistic clinker temperature references. we normally reference the cooler efficiency at 1450°c for a true, real-world calculation as per the vdz standard. referencing cooler efficiency at lower temperatures, such as 1400°c, artificially increases the cooler efficiency.

at this stage, to preserve the clinker mineral structure, that is, its quality, the clinker has to be cooled very quickly to a temperature of approximately 150°c. a large amount of ambient air is introduced through seven clinker cooler fans to achieve the target temperature outlet. the ambient air is heated up to 290°c.

Cement Clinker Calcination In Cement Production Process

Cement Clinker Calcination in Cement Production Process

clinker calcination is the most crucial part of the whole process of cement manufacturing. at this stage, ground raw materials will be sent into the cement kiln and be heated at a high temperature to produce chemical reactions with each other, eventually forming clinker. in addition, clinkers that just complete the calcination will have a high temperature, thus a cooling machine is usually placed behind the rotary kiln so that the clinker can go directly into the cooler
