Blaine Air Permeability Apparatus/Blaine apparatus

This instrument is made according to the ASTM204-80 ventilation method of the United States.The basic principle is measured by using a certain amount of air through different resistances when passing through a compacted powder layer with a certain porosity and a certain thickness. It is widely used in the specific surface area of non-porous powdery materials such as cement, ceramics, abrasives, metals, coal rock, gunpowder, etc. Executive standard: GB / T 8074-2008Technical Parameters:1. Diameter of the inner cavity of the breathable cylinder: Φ12.7 ± 0.1mm2. The height of the sample layer of the ventilated circular simple cavity: 15 ± 0.5mm3. Number of holes in perforated plate: 354. Perforated plate aperture: Φ1.0mm5. Thickness of perforated plate: 1 ± 0.1mm6.Net weight: 3.5kg
