Influence of Fine Grinding on the Hydrolysis of Cellulosic

The relative influence of ball milling for various time periods on the course of enzymatic and dilute acid hydrolysis was investigated. The response of enzymatic hydrolysis to the extent of milling was quite dramatic. Cotton linters pulp was totally hydrolyzed in 10 days with 60 min of milling. The carbohydrates of red oak were 93% converted to sugar in the same time after 240 min of milling

Fine Grinding an overview ScienceDirect Topics

For very fine grinding (< 10 μm) of dry plant material, we use a device made up of a cylindrical rotor turning at 3,000 rev.mn − 1 in a stator with a slightly bigger diameter. Rotor and stator surfaces are equipped with parallel corrugations along the vertical axle. Fines are pulled toward the top. Pin mills have two discs equipped with pins that are parallel to their axle. One
