Features

1. Material refining technology makes high purity and low harmful element content (such as S,P ).
2. Through roll forging, material is processed and strengthened and material fibre is complete and uniform, which increases

integrated mechanical performance of material.
3. FDSP Company has the world advanced forging equipment and technology, electronic data processing systems and

perfect quality control system.

4. Ring die blank, generally chromiumalloy roll forgings, some factories use 45 ordinary carbon steel.
5. Hardness of blank must be controlled, ranging from HB170 to HB220. If the hardness is too high, the drill is easy to break

and happens with die hole when drilling. If hardness is too low, the surface finish of die hole will be not good.

6. In order to control blank inner material uniformity, every blank must be carried out with fault detection, which can avoid

defects such as flaw, pore-free, crackle and inclusions etc.
7. After machining and heat treatment process, hardness of ring die can be up to HRC 52-58 (inner diameter less than

350mm), HRC50-56 (inner diameter more than 350mm), more wearable and anti-corrosion.

8. In order to control hardness uniformity of ring die after heat treatment, we choose more than three points in each part of

trisection of peripheral direction to test hardness and take average. The difference of hardness value between each part

should not be higher than HRC4.

9. According to the principle of metal material science combined with gas quenching and C, Cr, Mn, Ni, V elements content is

optimized, forming the standard of ring die.

Production process:

1. Precision Machining:
CNC machining center
CNC machining center assure high dimensional accuracy, geometric tolerance and surface roughness.
2. Hole Machining
Germany gun drill
The quality and service life of die is guaranteed.
3. Vacuum Hardening

Relations between die hole structure and pelleting:

Straight hole and release stepped hole is suitable for compound feed processing.
External conical hole suitable for the processing of high-fibre feed like de-fat chaff.
Internal conical hole and compression-type stepped hole 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.

Other Spare Parts

We can customize all the spare parts for the pellet machinery. Like roller shell, hammer mill, bolts etc.
