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 (9) are disposed away from each other at an interval in the axial direction of a rotary shaft (8). Each of the cutter plates (9) includes a plurality of pulverizing blades (9b) aligned circumferentially along the outer periphery edge of the cutter plate. At least one of the cutter plates (9) is fixed to the rotary shaft (8) in a state that the cutter plate is inclined with respect to a direction orthogonal to the rotary shaft (8).
摘要:
A paper shredding mechanism (10) has two rows of shredding units (400) mounted for rotation in opposite directions, each of which has a flat body (410) with a periphery (412) and left and right sides, at least one piercer (430) projecting from the periphery (412) for piercing and cutting a paper sheet (P) fed through between the two rows, cutting in a first direction transversely of the paper feeding direction, and a shearing edge (422) on each of the left and right sides alongside the periphery (412). The piercer (430) has a cutting edge (432) which extends across the left and right sides of the body (410). The shearing edge (422) bears laterally against the same of an adjacent unit (400) of the other row. The two shearing edges (422) together act as shears for cutting the paper sheet (P) in a second direction parallel to the feeding direction.
摘要:
The invention relates to a comminution device for the production of particles (16) from a strip-shaped material (17), said device comprising a longitudinal cutting device (1) having a first cutting roller (2) and having a second cutting roller (3), and a transverse cutting device (4), which is disposed downstream from the longitudinal cutting device (1), wherein the first cutting roller (2) and the second cutting roller (3) each have special profiles according to the invention.
