The Effect of Moisture on the Particle Size Characteristics of Knife-milled Beech Chips

The paper presents the effect of moisture on the particle size distribution of knife-milled beech chips. The beech chips of 0.5, 7.5, 15.9 and 30.9 wt % in moisture were milled by a knife mill equipped with a single-bladed rotor under the constant peripheral speed of revolution of 10.2 m·s-1 (1,500...
