AUTOMATIC BLAINE APPARATUS.
MODEL AUTOBLAINEPLUS
Ref. 111-100440/1
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
of the following standards:
> EN196-6 Methods of testing cement Determination of
fineness.
> 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
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.
Automation
The operation of AUTOBLAINEPLUS is automatic in as
concerns to:
> 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
screen.
> Automatic storage of all test data results.
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 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.
