Impact of the Granulation Process on Color Texture of Compacts

摘要

This paper examines the effect of the granulation process on the color texture of compacted powders and granules.The objective is to obtain information to provide for a better comprehension of granulation mechanisms by using a pigment as a texture marker.This requires the establishment of a methodology both to qualify and quantify the spatial variation of color on the compact surface.This is achieved by color image analysis accompanied by both a statistical and a spatial treatment of the color content in the images.
