Embodiment 1

[0017] Such as Figure 1 to Figure 3 As shown, a ring die for a granulator includes a ring die body 1, a plurality of ring die holes 1-1 are opened on the ring die body 1, and the ring die holes 1-1 are through holes, and the adjacent The central connecting lines abcd of the four ring die holes 1-1 are square. That is, the arrangement of the ring die holes 1-1 in the horizontal and vertical directions is parallel and equidistant, the ring die holes 1-1 are aligned in each row, and the ring die holes 1-1 are also aligned in each row. The effective aperture diameter ΦD of the ring die hole 1-1 is 3.0mm.

Embodiment 2

[0019] Such as Figure 1 to Figure 3 As shown, a ring die for a granulator includes a ring die body 1, a plurality of ring die holes 1-1 are opened on the ring die body 1, and the ring die holes 1-1 are through holes, and the adjacent The center line abcd of the four ring die holes 1-1 is rectangular. That is to say, the ring die holes 1-1 are arranged in parallel horizontally and vertically, the ring die holes 1-1 are aligned in every row, and the ring die holes 1-1 are also aligned in every row. The effective aperture diameter ΦD of the ring die hole 1-1 is 3.5mm.

Embodiment 3

[0021] Such as Figure 1 to Figure 3 As shown, a ring die for a granulator, this embodiment is the same as Embodiment 1, the difference is that the effective aperture diameter ΦD of the ring die hole 1-1 is 2.5 mm.

Abstract

The invention relates to a circular mold granulator, and particularly relates to a circular mold for the granulator. The circular mold for the granulator comprises a circular mold body (1), a plurality of mold holes (1-1) of the circular mold are arranged on the circular mold body (1); and connecting lines of centers a, b, c and d of four adjacent mold holes of the circular mold are in a rectangular shape. Due to the adoption of the structure, the number of the mold holes of the circular mold is greatly increased, the number of the mold holes of the circular mold within the effective area on the work surface of the circular mold is increased, the hole-opening percentage of the circular die is high, the production efficiency is high, and the yield is high. Moreover, the effective aperture phi D of each mold hole of the circular mold can have any value smaller than or equal to 3.5mm. Therefore, the hole-opening percentage and the production efficiency are improved, and the cracking phenomenon of the circular mold is avoided, so that the circular mold for the granulator can work in the optimal state, and the service life of the circular mold is prolonged.

Description

technical field [0001] The invention relates to a ring die granulator, in particular to a ring die for the granulator. The invention belongs to the technical field of mechanical equipment manufacturing. Background technique [0002] At present, the ring model pellet mill is widely used in feed, grain, food, medicine, chemical industry and other industries. The ring die is an important working part and wearing part of the granulator. The ring die has a direct impact on the power consumption, output and quality of the granulator, so the ring die plays an important role in the granulator. The structure of the ring die includes a ring die body, which is provided with a number of ring die holes, and the powdery materials in the ring die are extruded from the ring die holes to granulate the powdery materials into pellets. The opening ratio of the working surface of the ring die has a great influence on the production of the ring die. On the basis of ensuring that the ring die h...
