AUTOMATIC BLAINE PERMEABILITER AUTOBLAINE

AUTOBLAINE PERMEABILIMETER

Standards: According to EN 196-6, ASTM C204 and equivalent

PRODUCT OVERVIEWThe Blaine apparatus is used to determine, through materials testing, the fineness of cement (and other powdery products) in terms of specific surface in cm2/g.

The device enables to determine quickly and automatically the fineness of cement avoiding boring calculations and checking charts, reducing human errors in the timing, obtaining immediate reliable and repetitive.

PERMEABILIMETER CONTENTS

  • A frame or support in steel plate where all the device elements are located.
  • A “U” manometric glass tube, with 3 marks, according to the standard requirements, in which the manometric liquid is poured.
  • A stainless permeability cell, with 12,7 mm inside diameter with a perforated disc according to the standard and a piston or ram to compact the sample.
  • An electric vacuum pump with air flow control.
  • A Pt 100 probe, to measure automatically the temperature during the test.
  • Two photoelectric cells, to determine the falling time in seconds of the manometric liquid between the two marks.
  • A sensitive keyboard to calibrate the cell, introduce data and calculate automatically the results, by means of an internal microprocessor.
  • A digital indicator with 6 digits to read directly the specific surface in cm2/g.

FUNCTIONS PERFORMED AUTOMATICALLY

1. Sealing check of the system.
2. Controlled aspiration of the manometric liquid until the upper mark.
3. Determination of the falling time of the manometric liquid between the test reference marks with a resolution de 0,01 s.
4. Simultaneous measure of the temperature.
5. Process of the data introduced in the memory: time in seconds and temperature.
6. Direct application of the mathematical formulae specified in the standard with an automatic   correction of air viscosity and the display of the specific surface result in cm2/g.
