Improving particle size distribution in cement production
Jun 17, 2019 Assessing cement fineness. In the past, cement producers gauged cement fineness (i.e., cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill.

Particle Size Distribution: Particle Analyzers MICROTRAC
The example below shows a particle size distribution with 5% oversize. Here, 95 % of the particles are below 1 mm, the oversize has a size of 1 1.25 mm. This can be quantified by Q3 (1 mm) = 95% or 1-Q3 (1 mm) = 5%. This example also shows that the addition of oversize increases the mean particle size, while the median remains unchanged.

Apr 27, 2019 The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions. For light ball loads the ball mill is less efficient as might be expected.

Perfecting Particle Size Distribution (PSD) for Tableting
Oct 23, 2020 The particle size distribution relating to tableting is often expressed as the weight distribution at the following percentiles: 90th (d90), 50th or median (d50) and 10th (d10). One critical parameter is the width of the particle size distribution. This is often measured as a ratio of d90 / d10. In general, a bell normal particle distribution
