determination of the particle size in the classifier

Particle Size and Strain Analysis by XRay Diffraction. Particle Size and Strain Analysis Application Note Particle Size and Strain Analysis by XRay Diffraction Background When crystallites are less than approximately 1,000 D in size, appreciable broadening in the xray diffraction lines will occur. These regions may in fact correspond to the

The Sizing & Selection of Hydrocyclones

Historically, classification has been defined as the particle size of which 1% to 3% reports to the cyclone overflow with coarser particles reporting to the cyclone underflow. Recent investigations have defined classification as the particle size of which 50% reports to the overflow and 50% to the underflow, or the so-called D50 C point.
