Measuring and controlling the particle size distribution of cement is important both in order to achieve the desired product performance and to control manufacturing costs. Laser diffraction is the more popular method to determine the particle size distribution as the technique is quick, easy, reproducible, and provides a complete picture of the full size distribution.

In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.

The specific surface area of the cement (area per unit mass) can be calculated from the particle size distribution parameters. The greater the slope, the narrower is the distribution. For equal specific surface area, cements with a narrower distribution have a smaller position parameter x' and thus a higher proportion of the fine particles.

Cement can be a problematic material in the application of particle size analysis. First, the size distribution itself is extremely broad, extending in most cases over two to three orders of magnitude, from about 100 µm down to below micrometer size. In general, sizing techniques work best over a limited size range.
