Effects of Mill Speed and Air Classifier Speed on …
which results in improved Blaine and cement strength. However, too fine grains could halt Blaine quality due to cause agglomeration [11]. Ghiasvand et al. [12] reported that the increase in milling time increases the Blaine for almost all types of cements. Typically, the increase in Blaine, measured in cm. 2 /g is twice as compared to time
FINENESS OF CEMENT BY BLAINES AIR PERMEABILITY METHOD (IS …
Coarse cement particles settle down in concrete which causes bleeding. Approximately 95% of cement particles are smaller than 45 micrometers, with the average particle around 15 micrometers. In the early 1900s, cement fineness was expressed as the mass of cement per fractional size (percent weight retained on specific sieve sizes).
Blaine value vs position parameter
If you (really) want to evaluate the Blaine from the Rosin-Rammler parameters, you can do that with a bit of algebra. Here the formula: [1] Blaine = Shape * 6/ro/xo *

cement blaine and residue on 45 micron control? -Page 1 …
Hello Raju, Since both are a measure of particle size, residue is normally linked to Blaine. But not always. It depends on the particle size distribution of the cement and this is driven by several things including mill design, ball charge (or grinding pressure in a roller mill), clinker hardness, gypsum content, and the quantity and hardness of mineral fillers used (eg limestone).

To perform this test, NIST Portland Cement #114q is required by the ASTM standard for calibration. The Semi-automatic Blaine Apparatus provides more accuracy and precision than provided by the manual Blaine Apparatus. Calibration of this unit is done using a cement sample reference, such as NIST 114q.
