PULVERIZER, ABSORBER MANUFACTURING APPARATUS PROVIDED WITH THE SAME, AND PULP SHEET PULVERIZING METHOD

摘要

Provided are a pulverizer that enables to uniformly pulverize a pulp sheet in the axial direction of a rotary shaft, an absorber manufacturing apparatus provided with the same, and a pulp sheet pulverizing method. A plurality of cutter plates are disposed away from each other at an interval in the axial direction of a rotary shaft. Each of the cutter plates includes a plurality of pulverizing blades aligned circumferentially along the outer periphery edge of the cutter plate. At least one of the cutter plates is fixed to the rotary shaft in a state that the cutter plate is inclined with respect to a direction orthogonal to the rotary shaft.
