101-What is D90
D90 is particle size distribution D90, it represents the particle diameter corresponding to 90% cumulative (from 0 to 100%) undersize particle size distribution. In other words, if particle size D90 is 117.8um, we can say 90% of the particles in the tested sample are smaller than 117.8 micrometer, or the percentage of particles smaller than 117.8 micrometer is 90%. D90 is a typical point in particle size distribution analysis. D90 is also divided into Dv90, Dw90 and Dn90. Dv90 means volume D90, whereas Dw90 is mass D90 and Dn90 is number D90
HMK-200 air jet sieve measures D10/D50/D90 working on air jet sieving method accuractely. During this periodl, 3 meshes are used to represent particle size distribution D10, D50 and D90.
