Shortened cement retention time in the mill leads to a less intensive use of the grinding system, therefore reducing mill maintenance cost per ton of cement. Moveover, the reduction of the mill media coating and the improvement of pack set prevent the mill stoppage due to blockage (diaphragm and outlet grit cleaning, silo blockage ...

With coal as a fuel the recommended retention time in calciner should be at least of 3.3 seconds to ensure fuel combustion in calciner. With the development of cement technology, 60% of the fuel required is fired in calciner and 90 to 95 % of calcination duty is done outside the kiln.

As less grinding energy is used in producing a cement of a required fineness in an OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently
