high blaine - high residue - Page 1 of 1 - International Cement Reviewi am currently experiencing short setting time on OPC cement with a blaine of 4000 cm2/g but the residue on a 45 micron sieve is 30%. The ball mill is open circuit. Charge was added but still getting high residue. Can anyone explain to be why the blaine is high and residue also high? what can i do to.blaine raw mill,Trials on high quality cement with a Loesche vertical roller mill .power consumption of the mill drive of 26.5 kWh/t when grinding cement to a fineness corresponding to a specific surface area of 3850 cm2/g Blaine. Test runs carried out to take better account of market conditions established that the Loesche mill can also produce grade III cement as specified in the ASTM standard. This is.
