Minimization of variation in clinker quality

clinker in a coal mill. Recent studies have shown that the cement clinker variations have a greater effect on the workability and strength of cement. The unexpected variations may lead to serious disturbances in production in the form of poor compaction, too low early strength and strand slippages.
