The Rosin-Rammler distribution can be transformed to ln ln 1 1 P(D). ln(D) . ln(D ) (2.7) which shows that a plot of the log log reciprocal of 1-P(D) against the log of D will produce data points that lie on a straight line whenever the data follow the Rosin-Rammler distribution. This defines the Rosin-Rammler coordinate system.

In the cement industry, natural raw materials are processed to produce an end product which is a fine powder. As shown in the flow diagram, several size reduction processes are needed. The major raw materials are usually quarried, so that they begin the process as geological strata.


Plot of this function is linear in case of special axes used - logarithmic vs. double logarithmic scale. Diagram consisting of such scales is called Rosin-Rammler Diagram and MATLAB® tool for plotting size distribution data using such a diagram is proposed. Functions for determining the specific parameters are part of the tool as well. 2.
