Cement mill particle size distribution

  • 101 What is Particle Size Distribution D50, D50 Pa.

    What is Particle Size Distribution D50, D50 Particle Size Distribution If D10=3um, it means 10% of particles smaller than 3um As you know we show particle size from smaller to bigger, from 0 to 3um, 3um to 5um, then bigger and biggerAs a result the D50 value is always bigger than D10 You can treat particle size value as a mesh aperture size,all
