With conventional grinding tools of this type, great effort has been made to select wear-resistant materials and blade shapes that provide good cutting and friction properties in order to increase the beating ability, but in any case, the work is difficult. As a result, wear of the blade material occurs, and even if the material has a long service life, there will be continuous minute wear.Also, since the material is made of the same material, uneven or uneven wear can easily cause the blade surface to become a slippery surface, reducing cutting performance and reducing the beating. There were problems such as a sudden decline in performance, which was not completely satisfactory, and the cutting tools had to be replaced, which shortened the replacement period and led to a drop in operating efficiency.

に考慮してある。 As the foreign material 4, a ceramic sintered body,
Ceramic fibers or the like are used, but any material that wears preferentially to the blade material 3 and has a roughened surface that increases the number of unevenness and edges formed on the blade surface can be effectively used. In this case, it is preferable that the foreign material 4 is provided in the form of a lattice, a line, or a thin strip or corrugated sheet in the thickness direction, which is cast into one or more blade portions 2, and the blade material 3 and the foreign material 4 are It is designed so that unevenness is appropriately formed on the blade surface due to abrasion due to the mixture.

もよい。 Further, the blade material 3 with the blade part 2 is a disk blade made of an aggregate of divided members arranged and combined in a ring with the direction of the blade part 2 slightly shifted as shown in the first figure, or an annular body of an undivided one piece. It is preferable that it is detachably attached to the support member 1 by fixing means such as screws 5, but instead of the disk type, it can be arbitrarily selected to be constructed as a conical type or a cylindrical type suitable for refining of various paper stocks. . Further, the support member 1 to which the cutter material 3 is attached is disposed inside the casing as a movable plate via a runner or the like, but it may also be disposed as a fixed plate in the casing opposite a sliding plate.

Therefore, the raw material is supplied from the raw material supply port 7 to the casing 6.
When introduced into the runner 9, it passes between the blades 2 of the refiner cutter that is rotating, and is beaten and discharged from the discharge port 8. Even if the change occurs due to slight wear, the presence of a foreign material 4 buried in the blade part 2 causes the blade surface to always be rough due to the difference in the degree of wear with the blade material, and there are many edges, making it easy to apply paper material. , the state where numerous cuttings and frictions are applied allows optimal beating processing to be performed from the initial stage to just before the time to replace the blade, and the beating capacity can be increased without creating fine fibers, reducing the driving force required for beating work. Compared to conventional blades, it can be reduced by 25%, contributing to energy savings.

In the present invention, a different material exhibiting abrasiveness different from that of the cutter material is continuously buried in the cutter material at a predetermined depth from the surface of the cutter, so that even continuous slight wear of the cutter material can be avoided. It is possible to constantly maintain the uneven surface that increases the beating capacity suitable for refinning, and the driving force required for beating work can be significantly reduced.
In addition to contributing to energy savings, the blade surface is always rough, has a large number of edges, and holds the paper material well, and continuously applies a lot of cutting and friction, making ideal beating work possible and increasing the operation rate. There is a practical effect that can greatly improve the performance.
