Red rivers of segregation

09 March 2016, Published under Cement News

This month’s Technical Forum ponders the tendency of particulate solids to segregate at various stages of the cement manufacturing process with critical implications, especially in the clinker cooler. Red rivers are caused by particle segregation in the cement production process and can cause premature equipment failure As this month’s Technical Forum focusses on the phenomenon of segregation in the cement manufacturing process, let’s start with a definition of segregation. ...

The modern cooler

16 November 2015, Published under Cement News

Clinker cooling is a key step in the pyroprocessing system. The cooler is essential for recuperating heat from the clinker and cooling it sufficiently for the cement milling operation. However, the primary objective of the cooler is to transport hot clinker from the kiln. During this process, the cooler fulfills a range of functions and its design needs to take into account the requirement to transport clinker efficiently as well as help to recover waste heat and obtain the optimum clinker p...

Thinking ‘inside the box’

24 September 2012, Published under Cement News

The increased size of preheaters and pyrolines has significant repercussions for the clinker cooler element of the cement production stage. Clinker coolers often need to be modified or changed when expansion projects could lead to potential bottlenecks. To ensure stable and efficient clinker cooling at UltraTech’s Grasim South cement plant, FLSmidth retrofitted a Cross-Bar™ cooler which has enabled the Indian cement producer to increase capacity while reducing downtime and improving energy s...
