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).
1. Alloy dies
This is the choice for many feed processors because of their good abrasion and breakage resistance.
2. Stainless steel dies
They have the best abrasion and breakage resistance as well as good corrosion resistance.
Process Of Ring Die
CNC machining center :assure high dimensional accuracy,geometric tolerance and surface roughness.
Our company's die is made by international advanced German gun drill, tools and drilling hole software.Which ensures process conditions as drilling required, therefore high pelleting output, quality and debugging convenience
American vacuum furnace:High vacuum degree, no oxidation reaction in ring die surface, ensuring original smoothness of die hole inner surface ,has long service life and high quality. High cooling speed ensures more even distribution of carbide hardenability and uniformity of ring die.
Relation between die hole structure and pelleting
1,Straight hole and release stepped hole
It is suitable for compound feed processing.
2,External conical hole
It is suitable for the processing of high-fibre feed like de-fat chaff.
3,Internal conical hole and compression-type stepped hole
This applicable for the process of herbage powder feed of light proportion.
We should try to avoid using release stepped hole(pressure-relief vent)
Because discharing is not easy for holes in the rows of the edge of ring die, pressure-relief vent is designed there.
