The SZB-9 Automatic Blaine Air Permeability Apparatus perform the test for determining the fineness of cements, limes and similar powders expressed in terms of their specific surface according to the above testing standards. The fineness of cement can be automatically measured as specific surface by observing the time taken for a fixed quantity of air to flow through a compacted cement bed of specified dimensions and porosity.The method is comparative rather than absolute and therefore a reference sample of known specific surface is required for calibration of the apparatus.
1.Power supply voltage: 220V±10%
2．Time count range: 0.1second to 999.9 seconds
3．Time count precision: <0.2 second
4．Measurement precision: ≤1‰
5．Temperature range: 8-34℃
6．Ratio surface area number S: 0.1-9999.9cm2/g
7．Use range: use range described in standard GB/T8074-2008
Accord with GB/T8074—2008 state standard we develop the new model SZB-9 Auto Ratio surface tester. The machine is controlled by computer, and operated by soft touch keys, auto control total test process. Auto remember the coefficient, display the ratio surface area value directly after test work finished, it also can auto remember the test time.
The Automatic Blaine Air Permeability Apparatus is used to determine particle size of powder materials such as portland cement and lime in terms of their specific surface according to the Blain technique.The microprocessor-controlled Automatic Blaine Air Permeability Apparatus is with a manometer column operates with 1 or 2 cells.After enter the specifications of sample to control unit, the device makes the test automatically and post the results to printer.The device has an interface for a generally commercially available printer.
This automatic electronic apparatus with microprocessor is equippedwith an automatic airproof device.The apparatus consists of a flat enclosure with a manometer columnand with 4 components stainless steel measuring cell.Depending to the cement porosity and its density, the equipmentcalculates automatically the masse that you have to test, determinesthe constant K according to standard cement, records the test resultswith possibility to elaborate an average value of different tests.RS 232 port. The defining of final Blaine value is automatically givenby the apparatus. Supplied complete with accessories
