Description of key information

MMD= 325 µm
D10= 44 µm
D90= 1245 µm

Additional information

The measurement was using laser diffraction method according to ISO 13320.

The test item was sieved using a sieving machine with a 2 mm mesh sieve. Particles with a size <2 mm were applied to the laser diffraction instrument.

In addition, the values [vol%] for the particle size fractions are as follows:

Particle size fraction


<4 µm


<10 µm


<100 µm
