P-21　Examination of the Pulverizing Force Threshold in Acetylating of Lignocellulose Powder using Vibration milling with Ring Media

Abstract

In this study, the pulverizing force acting on lignocellulose powder was varied arbitrarily in the preparation of acetylated powder using a ring media mill, and the pulverizing force threshold in the preparation of acetylated powder was examined. By changing the ring medium mass and chamber frequency, the pulverizing force was arbitrarily changed. As a result, the pulverizing force threshold was found to be 27.36 MPa.
