摘要： In a process for producing a particulate polysaccharide derivative by dry-grinding a moist polysaccharide derivative the median length of the particles after dry-grinding is controlled by controlling the moisture content of the polysaccharide derivative prior to dry-grinding. Advantageously the median length of the particles after dry-grinding is adjusted to a first value by a first moisture content of the polysaccharide derivative prior to dry-grinding and is adjusted to a second value by a second moisture content.
