That is, the die 14 formed of a disc-shaped perforated plate is mounted horizontally with respect to the ground line, and has a structure in which a plurality of rollers 13 revolve on the upper surface thereof and rotate by friction with the die surface. The revolution of the roller is performed by a shaft inserted in the center of the die. The raw material is supplied to a hopper 10, kneaded into a fluid suitable for extrusion granulation by a paddle mixer 11, and the supply amount is adjusted by a slide-type adjusting orifice 12 to be supplied onto a roller 13. The raw material is sandwiched between the die and the rotating roller, extruded into a filament from the hole of the die, cut into appropriate lengths by the rotating knife cutter 14, and granulated.

Therefore, when the dies are replaced due to obstacles such as abrasion and breakage, even the portions where such dies do not occur are replaced. It was extremely uneconomical. In order to solve this problem, the dies should be assembled so that only the parts where the above-mentioned obstacles frequently occur can be replaced.However, as in the case of fertilizer granulation, strong vibration and large In the case of granulation involving pressurizing force, there is no prior art which clearly indicates an assembly structure capable of preventing troubles such as dropping of a die.

As shown in FIG. 2, a housing 21 for housing a split perforated plate, and a communication hole 22 through which an extruded product of a striated body passes.
And a shaft insertion hole 23 through which a shaft for transmitting power to the roller is inserted. A side wall 211 on the center side of the housing portion 21 is provided with means for preventing floating of the split type perforated plate. In addition, a communication hole 22 is formed in the bottom surface 212 thereof. Reference numeral 24 denotes a female screw for inserting a push-in bolt for reliably preventing floating or rattling of the split-type perforated plate when granulation conditions such as vibration and pressure are more severe.

The depth is such that the split perforated plate is not easily damaged by the pressure from the roller.
The size varies depending on the pressure, material, and the like that the split-type perforated plate receives, but when granulating fertilizer using SKD-11 alloy as the material, it has a depth of 5 to 20 mm and a frame thickness of 10 to 20 mm. It is desirable to set it to 50%.

Means for preventing the split perforated plate from lifting are provided. One example is a wall taper structure generated by enlarging the bottom surface of the housing portion from its opening surface as shown in FIG. 2, but the present invention is not limited to this. Like the gear structure, a structure in which the side wall of the housing portion and the side wall of the divided perforated plate are meshed with a plurality of teeth may be used. In the tapered structure, the side wall 211 and the bottom surface 2
By making the angle between 12 and 85 to 89 °,
The balance between the floating prevention effect of the split perforated plate and the ease of replacement thereof is extremely improved.

通し押圧を加えることもできる。The outer side wall of the housing 21 is normally perpendicular to the ground line. If the granulation conditions are severe and the floating or rattling of the split-type perforated plate is concerned, in order to further ensure the floating preventing means, insert a pushing bolt from the outside of the frame and press it. Can also be added.

慮した適宜数と径の大きさが選択される。A communication hole 22 for guiding the striated body extruded from the split perforated plate to the cutting step is formed in the bottom surface 212 of the housing portion 21. The number of communication holes may be singular or plural. However, since the bottom surface 212 also functions as a mounting table for the split-type perforated plate, if it is a single unit having a size substantially equal to the area of the bottom surface 212, the supporting force of the split-type perforated plate depends on the granulation conditions. Since there is a shortage, the number and the size of the diameter are appropriately selected in consideration of this.

11 has a fitting structure corresponding to the lifting prevention means. In the case of the lifting prevention means shown in FIG. 2, the center side wall of the divided perforated plate has a tapered structure with an enlarged bottom surface. Further, if the lifting prevention means is a meshing structure, the toothed structure conforms to the meshing structure.

An appropriate material is selected from metals or alloys such as typical mechanical structural steels according to the type of granulation raw material and the granulation conditions. Under granulation conditions with severe wear, a split-type perforated plate made of a material having high hardness and toughness is desirable, and under granulation conditions with large damage such as breakage and cracks, a material having high toughness is desirable.

If the molding cannot be performed or the dimensional accuracy of the molded product becomes a problem, only the defective portion needs to be replaced, so that economical granulation can be performed. Such an effect becomes more remarkable as the size of the extruder increases, because ordinary dies are difficult to process.
