Fineness - Blaine Permeability BLAINE PERMEABILITY - AUTOMATIC APPARATUS AUTOMATIC BLAINE APPARATUS. MODEL AUTOBLAINEPLUS The Blaine apparatus is used to determine the fineness of cement (and other powdery products) in terms of specific surface in cm2g_1 or nr^kg-1 The digital Blaine Permeability AUTOBLAINEPLUS model is manufactured according to specifications > EN196-6 Methods of testing cement Determination of > ASTM C 204 "Fineness of Hydraulic Cement by Air Permeametry Method". In this test, cement is compressed under conditions defined by standard, taking a certain amount of air through the powder compacted. The resistance to air flow is directly proportional to the fineness of grain, as long as the same testing 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. The operation of AUTOBLAINEPLUS is automatic in as > Automatic calibration with calculation of the K contant of the equipment according to EN and/or ASTM. >Test performing: fluid aspiration, timing of the fall and detecting pass between the glass tube marks. > Making all calculations, showing the test results in the > Automatic storage of all test data results. 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 overcomes 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. Operating menus of touch screen Elements included in the standard supply Cement Catalogue
