Mar 20, 2016 Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids or liquid-to-solid ratio in a sample of pulp. This figure is valuable in two waysdirectly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.

The number of openings is the mesh size. 5 mesh screen means there are five little squares across one linear inch of screen. A 200 mesh screen has 200 openings, and so on. As the number describing the mesh size increases, the particle size decreases. Higher numbers equal finer powder. Mesh size is not a precise measurement of particle size.
