Image analysis provides a very useful method for the measurement of the size distribution of granular materials. The method is very useful when the grains to be measured are very small (1 ？ 25 μm), or are imbedded in a solid matrix. The techniques of measurement are described and the analytical methods for the transformation of random chord measurements made on section to three-dimensional size are provided in a convenient form. An example is given using data obtained from a modern automatic image analyser. Traditionally, this technique is applicable only to spherical particles, but the method presented in this paper can be used for particles of irregular shape which enhances its utility considerably. |
