The desired particle size may not have been included in the original particle size analysis. The two common models used include: Gates-Gaudin-Schuhmann Model (GGS) Rosin-Rammler Model (RR) The RR model is typically satisfactory for coarse distributions. The GGS model is generally considered more precise for fine particle size distributions. It may be needed to perform model

MoreThe roller mill provides a particle size distribution that’sfrom 50 to 100 percent more uniform, with 50 to 75 per-cent fewer fines, than distributions produced by other at-trition milling equipment. This means that no classifyingstep is required after reduction in the roller mill, and themill produces minimal waste in fines, eliminating a needto discard, reprocess, or sell the waste.

More2016-3-21 The changing particle size distribution of the milled good as a function of time is mosteasy to characterize qualitatively if the material has initially only one particle size. Atthe start of milling the ﬁrst size class is continually diminished, (Curve A Fig. 3) ﬁrstfaster and then slower. An average particle size class is initially built up. With furthermilling time this size class reaches a maximum percentage (Curve B Fig. 3) since thisclass is milled to a smaller particle size class. Very small particle size classes evolvewith time during the milling
