This paper is concerned with the power required to crush wood and bark, as well as with the size distribution and volume of the crushed particle.
The crushers used were of the hammer, grinder, and blade types.
The sphere equivalant diameter, dv, determined by the volume of the particle, was set as the size index for the particles crushed by the hammer and grinder-type crushers. The specific surface area Sw, was chosen as the size index for the particles crushed by the blade-type crusher. The power requirement followed Kick's law for the hammer and grinder type crushers where dv was used as the variable, and Rittinger's law was used for the blade-type one where Sw, was used as the variable.
