machine for pellets of two series

As we all know, particle machine divided into two series - Series with flat die ring mold series.
Everyone should be familiar ring nmb machine pellet, because in many domestic and foreign enterprises are using a ring mold feed granulator. Because do feed raw materials are refined, such as corn, soybean meal, cottonseed meal, etc., bonding rate, another former granulation quenched with steam, you can forage briquetting machine
Play a softening of the material in advance, cured, thereby better granulation and increased gloss particles. But like straw, wood chips and other crude fiber, low adhesion itself, difficult to shape, and if used as pellet mill machine, the need for high density, so they need a lot of pressure to achieve the density of the particles, which invisibly increase the difficulty. Renewable energy in recent years gradually rise, the market is being promoted as a fuel particles are ring die pellet mill to do feed evolved from the ring mold machine, so there are still many shortcomings to us to improve.
