Abstract

The utility model provides a circular die for a hay pelleting machine, which is mainly used for processing hay pellets. The circular die is formed by a circular die body (4), wherein a plurality of die holes are formed in the circular die body (4), and each die hole consist of an effective pelleting section (2) and an outlet (3); a conical inlet (1) is formed in one end of each effective pelleting section (2), and the rest part of each effective pelleting section is a straight hole; the ratio of the length L of each effective pelleting section (2) to the diameter D of each effective pelleting section (2) is 7-8; the taper angle of each inlet (1) is 12-16 degrees; the taper angle of each outlet (3) is 8-10 degrees, and the height h of each outlet (3) is 0-3mm. The circular die has the beneficial effects that: the molding effect and efficiency can be improved when the hay pelleting machine is used for pelleting hay powder, the processing cost can be reduced, and the service life of the circular die can be prolonged.

Description

Herbage circular mold for granulator

Affiliated technical field

The utility model relates to a kind of herbage circular mold for granulator, is mainly used in processing in the ring die pelleter of herbage particle, belongs to granulation technical field of processing equipment.

Background technology

At present, ring die pelleter is widely used in the industries such as feed granules, biological particles processing.Different material is selected different granulators, but its core component is ring die of granulator.It,, to improving product yield and quality, reduces energy consumption, and reducing cost has important impact.Common ring mould nib mainly contains straight hole, male-tapered hole, internal tapered hole etc., because the density of herbage grass meal is little, shatter value is high, not runny feature, make to be difficult to extrude herbage particle with the ring mould of common compacting feed granules, and energy consumption is high, the wearing and tearing of ring mould are large, therefore, need to change ring mode structure, make it be more suitable for the processing of herbage particle.

Summary of the invention

The purpose of this utility model is that a kind of ring mould that is applicable to herbage granulator will be provided, and granulating efficiency is good, and efficiency is high, while overcoming tradition ring mold pressing herbage particle processed, and the difficulty that is shaped, energy consumption is high, the situation of serious wear.

In order to reach the technical scheme that the purpose of this utility model takes, comprise:

A kind of herbage circular mold for granulator; ring mould body, consist of, on ring mould body, offer some nibs, the shape of nib comprises effective granulation section and grain export; the feeding mouth that described effective one end of granulating section is taper; remainder is straight hole, and grain export is also taper, and described effective granulation segment length is L; diameter is D; feeding mouth cone angle is α, and discharging opening cone angle is β, and discharging opening height is h.

The beneficial effects of the utility model are that forming effect and efficiency in the time of can improving ring mold pressing herbage grass meal processed, cut down finished cost, and increases the service life of ring mould.

Fig. 2 is the structure chart of nib in Fig. 1.

Below in conjunction with drawings and Examples, the utility model is further illustrated.

In Fig. 1: 1. feeding mouth, the section of 2. effectively granulating, 3. grain export, 4. ring mould body

The specific embodiment

At Fig. 1, in Fig. 2, for the ring mould of herbage ring die pelleter, by ring mould body (4), formed, on ring mould body (4), there are several nibs.Nib consists of effective granulation section (2) and grain export (3), the feeding mouth (1) that described effective one end of granulating section (2) is taper, and remainder is straight hole, described grain export (3) is also taper.

For guaranteeing the curring time of herbage particle in nib, described effective granulation section length L of (2) and the ratio of its diameter D are 7～8.

For improving the mobility of herbage grass meal, guarantee the pan feeding of nib, feeding mouth (1) cone angle is 12 °～16 °.

For guaranteeing that particle has good forming quality, improve the service life of ring mould, the grain export of nib (3) cone angle beta is 8 °～10 °, height h is 0mm～3mm.

It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement novel technical scheme, and the spirit and scope that do not depart from technical solutions of the utility model should be encompassed in the middle of claim scope of the present utility model.

Claims (3)

1. herbage circular mold for granulator; by ring mould body (4), formed; on ring mould body (4), have several nibs, nib consists of effective granulation section (2) and grain export (3), it is characterized in that: effectively granulate the section length L of (2) and the ratio of its diameter D are 7～8.

2. herbage circular mold for granulator according to claim 1, the feeding mouth (1) that described effective one end of granulating section (2) is taper, is characterized in that: feeding mouth (1) cone angle is 12 °～16 °.
