Pellet Mill Accessories Ring Die for Sale/Ring Die Stainless Steel Price

Brief Introduction of Ring Die

Ring die is the key part of Ring Die Pellet Mill in the large scale pellet plant to produce animal feed, wood pellets, poultry feed, livestock feed, aqua feed, bio-mass pellet and other granules.

The quality of ring die plays an important role in making high quality pellets and high output, also can save much maintenance cost for pellet manufacturers.

• FDSP is specialized in the production of dies for all the main brands of pellet mills. 
• We have rich experience in manufacturing ring die, and supply tailor-made ring dies with all kinds of models to satisfy clients' different requirements. 
• Our plant realizes full automation and adopts top technology, the ring dies manufactured to be exported to all over the world.

Working Principle of Ring Die in Pellet Mill Machine

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).

Different Materials of Ring Die

• Alloy Steel Dies

        This is the choice for many feed processors because of their good abrasion and    

        breakage resistance.

• Carbon Steel Dies

        They have superior corrosion resistance, making them the choice for processing

        operations involving corrosive chemicals.

• Stainless Steel Dies

        They have the best abrasion and  breakage resistance as well as good corrosion

        resistance.

Main Process of Ring Dies

• Precision Machining (CNC Processing)

        CNC machining center: assure high dimensional accuracy, geometric tolerance

        and surface roughness.

• Hole Machining (German Gun Drill)

       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

• Vacuum Hardening

        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.

We need to maintain and check the pellet mill's spare parts: ring dies, roller assembly,roller shell, gear shaft,screws, bearings, coupling etc. Because they are take up about 8% of the machine cost every year (primary for such as wood chipper, hammer mill and pellet mill.)
