To provide a method for efficiently pulverizing a fibrous material containing fibers to obtain an easily reusable powdery product of the fibrous material.
The method for pulverizing the fibrous material containing fibers enables to obtain an easily reusable powdery- or a chip-like product of the fibrous material. The method is carried out on a roll press 1, and comprises a step of roll-compressing/pulverizing the fibrous material between a pair of metallic rolls rotatably driven in a mutually-approaching directions in the roll press 1. In pulverizing the fibrous material, the step of roll-compressing/pulverizing is carried out on the press so that the pair of metallic rolls are energized and driven to apply a compression force to the fibrous material, whereby the fibrous material is spreaded out in its discharged direction due to rotation of the rolls. As a result, fibers contained in the fibrous material are torn, without flocculating, into small fiber pieces to make it possible to efficiently pulverize the fibrous material.
