Ring die pellet mill working principle
The basic structure of the pelletizing chamber is mainly composed of these parts: the die, the rollers, feeding scraper and cutting knives.
When the machine is started, the electric motor will drive the ring die to rotate. And the rollers will also revolve on its own axis due to the friction between itself and the die. By means of gravity and the centrifugal force generated by rotating of the ring die, material will be firmly attached to inner surface of the ring die. The feeding scraper will ensure the material to be continuously and evenly pushed forward along the die to be prepared for pelletizing.
Then the material is squeezed by the roller and the die, and with the gradually increasing pressure, the density of the material also becomes higher. Thus the material temperature will rise, which softens the lignin in it and makes it easier to be shaped. At this time, the material is compressed into the die holes and shaped into small cylindrical strips with diameters of 2 - 12 mm (depending on the size of the holes).
Die Materials
1. Alloy dies
This is the choice for many feed processors because of their good abrasion and breakage resistance.
2. Carbon steel die
They have superior corrosion resistance, making them the choice for processing operations involving corrosive chemicals.
3. Stainless steel dies
They have the best abrasion and breakage resistance as well as good corrosion resistance.
Ring die Customization:
We (FDSP) can manufacture the ring dies of different materials, types and hole diameters which are suitable for all top brand pelletizers, such as FDSP, ANDRITZ, CPM, BUEHLER, ZHENGCHANG, MUYANG, SHENDE etc.
Please offer the drawing and specifications of ring dies if you need.
