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.
