Thanks for your responses. Particle size is uncertain at this time. I am trying to make an excel spreadsheet to determine the velocity needed for any given size. The expected range is 100um to 1mm. The particulate is very dense (4000+ kg/m^3) and it is in diesel fuel. Again, this isn't really a slurry but instead a small amount of it in suspension.

needed to find out if the slurry particle size would be reduced as the slurry trav­ eled down the line. Perhaps most impor­ tant, the degree to which pressure would drop along the pipeline had to be deter­ mined, so that when a full-scale line was built, pump stations would be properly placed and would include sufficiently powerful pumps.

Choose accordingly with our sandpaper grit chart and by following the nuances in grades and material. What does the grit number on sandpaper mean? The grit of sandpapers is a rating of the size of abrasive materials on the sandpaper. The higher the grit number is equivalent to a finer abrasive, which creates smoother surface finishes.

Figure 6 – Particle size distributions from ball mill and vertical mill circuits. Since the automatic sampling system from concentrator II takes samples only from the combined streams on the regrinding circuit, a series of manual sampling campaigns were conducted along the year of 2012 to make this study possible. Figure 7 shows the results.

Granular materials in geotechnical engineering is generally considered to be mixtures of clay, sand, and gravel that commonly appear in slopes, valleys, or river beds, and they are especially used for the construction of earth-rock-filled dams. The complexity of the constitution of granular materials leads to the complexity of their properties. Particle size distribution (PSD) has a great ...

How the solid-particles behave in the mixture—whether they distribute evenly, and move suspended in the carrier-flow or segregate and deposit, depends as well on the solid properties (grain size, shape, density), on the properties of the carrier liquid (density, viscosity), on the operation parameters of pipe flow (velocity, pipe diameter, solid concentration) and on flow direction.
