AUTOMATIC BLAINE APPARATUS. MODEL AUTOBLAINE PLUS
Standards: According to EN 196-6, ASTM C204 and equivalent
PRODUCT OVERVIEW The Blaine apparatus is used to determine the fineness of cement (and other powdery products) in terms of specific surface in cm2g-1 or m2kg-1.
The digital Blaine Permeability AUTOBLAINEPLUS model is manufactured according to specifications of the following standards:
- EN196-6 Methods of testing cement Determination of fineness.
- ASTM C 204 “Fineness of Hydraulic Cement by Air Permeametry Method”.
The resistance to air flow is directly proportional to the fineness of grain, as long as the same testing conditions are respected.
The determination of specific surface serves to control the uniformity of the milling process in the cement plant, but can also be applied to control the particle size of other powder materials.
AUTOMATIONThe operation of AUTOBLAINEPLUS is automatic in as concerns to:

VALIDATION OF THE APPARATUS
| The AUTOBLAINEPLUS fulfills the requirements of validation demanded to the automatic methods for the determination of the refinement Blaine, and described in standard ASTM C 204-07, chapter 12. The performance of the AUTOBLAINEPLUS overcome in accuracy and precision to the manual method, because the errors in the measurements of time are much lower. Calibration of the equipment must be done using a cement surface standard reference, as for example the standard reference material NIST 114q. For optimum results testing should be carried out in a room with controlled temperature. |
