Rosin and rammler
WebThe distribution curve that is widely used in industrial practice was developed by Rosin, Rammler, Sperling, and Bennett in the 1930s (Rosin, Rammler, Sperling, 1997 Rosin and Rammler, 1933 Bennett, 1936). They found out that the size distribution of coal dust and of other crushed and milled materials like cement follows a probability curve ...

WebMar 21, 2007 · Discussions (1) Useful functions for manipulating and fitting data using the modified Rosin-Rammler distribution. These functions are pretty straightforward, and are provided primarily as a simple, useful curve-fitting example. Much of the code is adapted directly from the "fitcurvedemo" detailed in the MatLab help files. WebThe Weibull distribution or Rosin Rammler distribution is a useful distribution for representing particle size distributions generated by grinding, milling and crushing operations. The log-hyperbolic distribution was proposed by Bagnold and Barndorff-Nielsen[5] to model the particle-size distribution of naturally occurring sediments.
