In conclusion, all above are the fundamental differences between the ring die pellet mill and the flat die pellet mill. As the professional manufacturer of pellet mills, Whirlston always offers you the latest news, the PLASTIC PET MOULD 07 first-class equipment and after-sales service.A pellet mill, also known as a pellet press, is a type of mill or machine press used to create pellets.Pressure adjustmentThe ring die pellet mill adopts the two screws in the middle of the eccentric wheel to adjust the pressure; while, the flat die adopts thread column center adjusting mechanism whose pressure is even.Discharging wayThe speed of the ring die is very high,so the breakage rate of material is high; while, the breakage rate of the flat die is low because of the low speed. Apart from it, the feeding is even. In addition, a large bearing can be chosen, which can enhance the bear ability of the roller. While, the flat die pellet mill make the material enter the pressing room because of its own weight. We will introduce four fundamental differences. The flat die pellet mill was designed around the turn of the 20th century to produce animals feed. Feeding methods The ring die pellet mill adopts mechanical feed system. In addition, we can adjust it in two ways: rotary manual and hydraulic automatic. The material is rotated at high speed and enters the granulating chamber. In addition, there are many differences. While, the ring die pellet mill was not designed until the 1950,s.   Pressure The ring die wheel diameter is limited by the mould, so the pressure is also restricted; while, the flat die mould does not limit the flat die diameter. In addition, it can not only improve the pressing force but also prolong the service life. In addition, the feeding is uneven. It is divided into two main types: ring die pellet mill and flat die pellet mill
