HMK-22 Fisher Sub Sieve Sizer – 11 – Test Powder-Particle Size Measurement
11.Test Powder-Particle size measurement
-Take the filled sample tube upright off the sample tube stand
-Put it on the base block assembly
-Turn the sample pressure calibrator until it reach 14
-When the sample pressure calibrator is fixed,move the calculator chart
-There is a sample height curve
-Point the red needle onto the sample height line
-Then we got the porosity of this sample 0.xx such as 0.72
-Remove the sample tube and put it onto test base
-Press tightly and the water level goes up
-When the level becomes stable the level valUe is the particle size of this powder sample.
-If the powder is coarser and the water level goes too high we can use range control II
-When turn to II, the water level comes down
-Read the value
-Mutiply by 2 and get the particle size of this powder.For example, if 6.4,then 6.4 x 2 = 12.8
