The role of the press roller in the press roller granulator


The correct use of the press roller is one of the most critical factors affecting the use of ring mold cattle feed plant. We found in the long-term production and service, there are a lot of ring die in the use of uneven working face, low hole rate, productivity decline, new ring mold cattle feed manufacturing plant can not produce material, and so on, most of the reason is due to the use of the pressure roller caused by the irregularities.



New ring die in the use of ring die animal feed business pellet machine is characterized by: face level off, but the smoothness of eye hole and guide in the mouth, did not meet the requirements of normal granulating smoothness, the eyes of the new ring die hole to the material resistance and friction are large (especially the small aperture ring die), and the old roller shell at both ends are serious wear and tear, and the material easily from two head and wear of roll shell sliding into relief groove, make new eye on both sides of the ring die orifice discharge confusing or discharge. Therefore, the new ring die must be used with a new roller shell. Ensure that the matching use of more than 100 hours, ensure that the new ring die face pressure uniform, hole rate and polishing rate meet the requirements. In order to play out the ring of the best use of efficiency. In principle, each ring die must be used at the beginning of a separate roller, can not be used in other ring die series with the same roller shell.
