Abstract

The invention relates to an improved circular die which comprises a circular die body, wherein the circular die body is a hollow cylinder; two rows of pelleting holes are formed in the die wall of the circular die body; a nonporous die wall is arranged between the two rows of pelleting holes; two pelleting holes are formed in each row of pelleting holes in the same horizontal line; four pelleting holes which are vertically adjacent are formed in a stagger manner. Compared with the prior art, the improved circular die has the remarkable advantages as follows: the structure is simple; the two rows of pelleting holes are formed in the die wall of the circular die body, and the nonporous die wall is arranged between the two rows of pelleting holes to enhance the overall intensity of the circular die, so that the service life of the circular die is prolonged; a connecting edge is adopted to enable the connection to be firm; the modified circular die is excellent in pelleting effect and satisfies the practical using requirements.

Description

[0001] technical field [0002] The invention relates to a ring die, in particular to a granulator ring die. [0003] Background technique [0004] At present, the working principle of the ring die granulator is that the crushed material that has been quenched and tempered is evenly fed into the pressing area in the ring die by the feeding mechanism through the die cover. Due to the strong extrusion of the pressure roller and the ring die, the material It is gradually compacted, extruded into the die hole of the ring die and formed in the die hole. Due to the continuous extrusion of the material between the die rollers, the formed material is continuously discharged from the die hole in a columnar shape, and then cut by the cutter. into particles of desired length. In the prior art, the die holes are distributed on the entire side wall of the ring die. This type of ring die has problems such as insufficient strength, which is easy to cause damage to the ring die, and will ...
