Cement grinding with Horomill | Industrial Efficiency ...
The Horomill is a compact mill that can produce a finished product in one step and hence has relatively low capital costs. Grinding Portland cement with a Blaine of 3200 cm 2 /g consumes approximately 23 kWh/t and even for pozzolanic cement with a Blaine of 4000, power use may be as low as 30 kWh/t. Development Status.
Influence of Stearic Acid on Portland Cement Performance ...
Different contents of stearic acid were added to mixtures, and the influences of stearic acid as grinding aids on portland cement performances, including specific surface, compressive strength, hydration heat, Ca(OH)2 (CH) content, C-S-H gel and ettringite (AFT) content were discussed in this paper. The results show that the addition of small amount of stearic acid is enough, and excessive ...
