环模制粒机是饲料机械四大主机之一,在很大程度上决定饲料加工产量,在饲料加工过程中占有非常重要的地位。环模是颗粒机的主要零件之一,又是颗粒机的主要构成部分。环模工艺参数质量,直接影响颗粒机产量和饲料质量,从而影响动物生长性能。不同品种饲料对环模的压缩比及模孔直径要求有所不同,压制不同品种的饲料,需要选用相应的压缩比和孔径,以获得所需质量的饲料颗粒。制粒机环模的孔径和压缩比等技术参数能明显影响动物颗粒料品质,颗粒的顺利出料主要与环模模孔表面的光洁度有关,采用相同孔径压缩比不同环模成形的颗粒,颗粒料的硬度随着压缩比的增大而明显增大;高压缩比对颗粒品质有利,颗粒外观光滑且有光泽,粉化率低,但会增加产品的生产成本,因此,环模作为颗粒机的关键部件,要求其具有良好的机械性能,研究综述环模主要结构参数的概念及环模主要参数对颗粒料质量和动物生产性能的影响。
Ring die granulator feed machinery is one of the four hosts, to a large extent, determine the feed processing output, feed processing occupies a very important position. Ring die is one of the main parts of the particle machine, but also the main part of the particle machine. Ring mold process parameters of quality, a direct impact on particle machine output and feed quality, thus affecting animal growth performance. Different varieties of feed on the ring mold compression ratio and die hole diameter requirements are different, pressing different types of feed, you need to select the appropriate compression ratio and pore size to obtain the desired quality feed particles. Granulator ring die diameter and compression ratio and other technical parameters can significantly affect the quality of animal pellets, the smooth discharge of the main particles and die cavity surface roughness of the hole, the same aperture compression ratio of different ring-shaped particles, particles The hardness of the material increases obviously with the increase of the compression ratio. The high compression ratio is good for the particle quality, the particle appearance is smooth and shiny, and the powdering rate is low, but it will increase the production cost of the product. Therefore, Of the key components required to have good mechanical properties, the research review of the main structural parameters of ring mode and the main parameters of the ring mold on the pellet quality and animal production performance.
